AVFoundation joining Audio files
Hi All, In our specific market video app we take videos and merge them together and they are used for advertising. We can add music or a voice over to the video before publishing. Now we have a way of adding a intro to the video that was previously kept in the photo roll. The issue is if we have a intro we can no longer add a mp3 music file to the video. I worked around this by changing the .mp3 files to .caf files, this works only problem is that the app now is huge as the files are 10x bigger than the mp3 files were. I need a way of adding compressed audio to uncompressed audio. Is there a way of doing this in AVFoundation (perhaps AVAudioMix) Can someone guide me in the right direction here please.

Re: Application size growing
For completeness sake. I thought I would share the answer. I realised that this was a good problem when I saw others were complaining about the same thing with no answers, it turns out that when capturing the video, iOS stores these files in the /tmp directory and does not remove them immediately or when app is restated or even the phone is restarted for some reason. So I cleared this out also after the video is marked for upload and the problem is completely resolved. Thanks guys for your assistance.

If this reproduces in the simulator, you can locate the app’s directory (buried way down in ~/Library) and examine the hierarchy to see where the 200MB is and what the file(s) look like. That should provide a clue. If it only happens on a real device, you can write a bit of code to recursively iterate the directory tree and log the files and amount of space. Or use the Devices Explorer in Xcode for a development version of the app and dump the contents of the app directory, or iExplorer which does a remarkably good job of inspecting most things on a real device (without jailbreaking it). ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Application size growing
Hi All, I write a video app for the auto industry basically, you shoot several short “segments” of your car and combine them then add a tune in the background. I take them in 1280X720 and then resize them and add the audio using AVFoundation. I store all the files I save into Documents/video and optionally save the final video to the photo roll. After the user has uploaded the video they clear the cache (documents/videos) and move on to the next vehicle The problem is the app is gaining about 200Mb after each movie and the only cure is to delete the app. Where is this all going if I write all my stuff into one place and delete the directory later? Does something I save into the photo roll count towards storage for my app? IS AVFoundation using some caches or creating files in some temporary directory? Anyone else seen anything like this?

Video bit rate
Hi All, I am taking video on in my iPhone app at 1280x720 this turns out at about 40Mb/min What I want is to drop the bit rate not the size using AVAssetWriter/AVAssetReader, is this possible or even the right way of doing this? I am able to get what I want by dropping the bit rate in an external app so can I achieve this on the phone?

Unicode chars in string
Hi all, I am pulling my hair out here trying to replace the unicode (r) symbol with \\00ea in a string. Is there a way of doing this as the NSString is a unicode String so it is interpreting it. As convenient that might be to most people it is killing me here. Any suggestions?

Re: Keychain issues with public key on iOS

Is there any chance you could share the ComputeSHA1 message with me? I know
you said it was only a wrapper for commonCrypto but I am so lost in this stuff
I want t check everything.

Oh dear. Any time I have to deal with the iOS keychain APIs I get either
enraged or sick to my stomach or both. Seriously.
So I strip the begin and end markers plus remove all the \n (is this
correct?)
And also base64-decode it, right? It definitely won’t work unless you do that
too.
(This looks like a PEM-encoded key; to make sure, you could look up the docs
on that format. But I think you’ve basically got it right.)
The SecItemAdd succeeds but I can never get it out again as
SecItemCopyMatching always returns null in the ref pointer but returns
errSecSuccess so I am really confused.
Yeah, this is a good example of where my rage/ulcer reactions come from. The
SecItem API is one of the worst things ever: it’s incredibly vague and
under-documented, and just does not seem to behave in reasonable ways or
return informative errors.
Here’s some code I have for this purpose. It’s been about a year since I’ve
worked with it so I’m no longer clear on all the details.
One thing to note is that the app this is for is using the SHA-1 digest of
the key as the “application tag” property for looking up the key afterwards,
thus the usage of the digest in the parameters to SecItemAdd.
Also, the weird stuff about converting the persistent ref to a regular one is
to work around a bug(?) in the keychain code, where you apparently have to
request a persistent ref when adding a new item, but then can’t work with
that ref unless you convert it to a regular one.
This code is the boiled-down end product of literally about ten cumulative
hours of frustration and experimentation, so it may be messier than it needs
to be. If someone knows how to do this more elegantly, I’m all ears.

Auto resize due to personal hotspot blue bar
Hi all, I have a perplexing issue where I think I know the answer but can not make it work I have a custom UINavigation controller with a custom titlebar This is achieved in the UINavigationController subclass in the - (void)viewDidLoad UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,49)]; imageView.image = [UIIMage imageNamed:@some_image]; [self.view addSubview:imageView]; in the same method I added the following self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleTopMargin; this works fine. if I turn on Personal hotspot or put a phone call in the background, I get a 20px extension to the status bar. what happens is the new bar extension pops over my image and the view drops down 20 px. what I wanted was my image in the titlebar to drop down with the view. So I tried to add to the imageView the following: imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleTopMargin; This had no visible effect. So I went to the ViewController that was to populate the navigation controller and set the auto-resize flags on the View to be the same as the UINavigationController subclass. Still no improvement. Can someone please point me in the right direction. Or have I got this right but something is wrong somewhere else?

Problems linking json-framework with ios application
All, I am building a library to be used by other apps. I have included the json-framework in the library project and used the -ljson flag as directed. Now this all works fine, until my app uses one of the JSON categories that the library implements. if I add the json-framework to the app it works, so it appears I am doing something wrong as the categories and objects created by the json-framework are not being exported. Has anyone done something similar or can anyone see what I am doing wrong?

really no idea where to look next. Can anyone assist me please?

Re: core data issues iOS 4.0.2
Fritz,
Thanks for the pointer, I had over looked this document in my own search. The
issue was that I had deleted the record ok, but just a few lines further down I
had referenced one of the fields of the deleted record... (only idiots do that!
) So the clue was from the document you pointed me to and specifically the
line Fail to break all relationships from other objects to that object. So I
went looking for a mistake like I found.
Once again thanks for your time
Regards
Damien

Core data backed UITableView
Hi all,
Here is the dumb question for the day.
I have a coredata backed UITableView. I populate a NSFetchedResultsController
and use that to source the rows and sections etc. All works well.
That is until I go to delete an item from the table.
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@commitEditingStyle called);
TheEntity *myEntity = (VideoEntity *) [fetchedResultsController
objectAtIndexPath:indexPath];
NSManagedObjectContext *context = [[self fetchedResultsController]
managedObjectContext];
[context deleteObject:myEntity];
//commit the delete
NSError *saveError = nil;
if (![context save:saveError]) {
NSLog(@CoreData save Failure);
}else {
//all good removed from coredata
//now delete from tableView
[self.myTableView deleteRowsAtIndexPaths:[NSArray
arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
Then I get an error like
*** Assertion failure in -[UITableView _endCellAnimationsWithContext:],
/SourceCache/UIKit/UIKit-984.38/UITableView.m:774
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of
rows in section 0. The number of rows contained in an existing section after
the update (3) must be equal to the number of rows contained in that section
before the update (3), plus or minus the number of rows inserted or deleted
from that section (0 inserted, 1 deleted).'
This appears to mean I need to remove it from the fetchedResultsController
before I remove it from the table. So as NSFetchedResultsController has no
remove facility I reload it. Is there a more efficient way of achieving this?
Regards
Damien

some advice on asynchronous control please
Hi All,
I have a situation where I am using a 3rd party library to manage content on
their service. When I delete an entry the method requires a call back all
good. Now I need to wait for that call back to be called to know if it was
successful or not. In the call back I can set a boolean to indicate success or
not but waiting for that to be set is my issue. What is the right way to wait
for it?
I think
while(!done)
{
[NSThread sleepForTimeInterval:1];
}
Just blocks the main thread which is not what I want at all as this also blocks
the run loop also.
Can anyone give me some guidance on the best practice for this situation?

Ok so I go to the source of the assertion failure

//
GDataHTTPFetcher* fetcher = nil;
if (isUploadingDataChunked) {

NSUInteger uploadChunkSize = [self serviceUploadChunkSize];
if (uploadChunkSize kMinimumUploadChunkSize) {
uploadChunkSize = kMinimumUploadChunkSize;
}
Class uploadClass = NSClassFromString(@GDataHTTPUploadFetcher);
GDATA_ASSERT(uploadClass != nil, @GDataHTTPUploadFetcher needed);
NSString *uploadMIMEType = [objectToPost uploadMIMEType];
fetcher = [uploadClass uploadFetcherWithRequest:request
uploadData:uploadData
uploadMIMEType:uploadMIMEType
chunkSize:uploadChunkSize];
} else {
fetcher = [GDataHTTPFetcher httpFetcherWithRequest:request];
}
So it appears the Class uploadClass =
NSClassFromString(@GDataHTTPUploadFetcher); line fails. This tells me that
there is no instance of the GDataHTTPUploadFetcher class at this time.
Ok so what did I miss in my method I can not find any definition of a
GDataHTTPUploadFetcher in the sample project.
I have provided my method below hoping someone can assist me by comparing mine
to theirs and showing me where I have gone wrong. I really appreciate your
assistance.

NSURLConnection POST issues
Hi All,
I have a solution for this problem that I am not at all happy with. I have
appended all of my html form variables into a single variable using ||| as the
field separators. This is a rubbish solution. I am looking for a more elegant
solution that is less like a dodgy hack.
Here is the problem and I am sure there is a reasonable and simple explanation
for my problem that I have over looked but I can not see it yet.
The Java servlet I am connecting to expects 6 variables:
String strProdName = request.getParameter(ProdName);
String strProdVersion = request.getParameter(ProdVersion);
String strProdBuild = request.getParameter(ProdBuild);
String strUserEmail = request.getParameter(UserEmail);
String strUserComment = request.getParameter(UserComment);
String strUserDevice = request.getParameter(UserDevice);
here is my code to send this data
- (void) transmitMessageToServer
{
NSMutableData *appendedData = [[NSMutableData alloc] init];
[appendedData appendData:[[[NSString
stringWithFormat:@ProdName=%@,[self applicationName]]
stringByAddingPercentEscapesUsingEncoding: NSASCIIStringEncoding]
dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]];
[appendedData appendData:[[[NSString
stringWithFormat:@ProdVersion=%@,[self productVersion]]
stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding]dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES]];
[appendedData appendData:[[[NSString
stringWithFormat:@ProdBuild=%@,[self productBuild]]
stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding]dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES]];
[appendedData appendData:[[[NSString
stringWithFormat:@UserEmail=%@,[self userEmail]]
stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding]dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES]];
[appendedData appendData:[[[NSString
stringWithFormat:@UserComment=%@,[self userComment]]
stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding]dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES]];
[appendedData appendData:[[[NSString
stringWithFormat:@UserDevice=%@,[self userDevice]]
stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding]dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion:YES]];
NSString *dataLength = [[NSString alloc] initWithFormat:@%d,
[appendedData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL
URLWithString:@http://somesite.com:8080/addcomment;]];
[request setHTTPMethod:@POST];
[request setValue:dataLength forHTTPHeaderField:@Content-Length];
[request setValue:@application/x-www-form-urlencoded
forHTTPHeaderField:@Content-Type];
[request setHTTPBody:appendedData];
[appendedData release];
[postLength release];
[request release];
NSURLConnection *messageConnection = [[NSURLConnection alloc]
initWithRequest:request delegate:self];
[[UIApplication sharedApplication]
setNetworkActivityIndicatorVisible:YES];
if(messageConnection)
{
responseData = [[NSMutableData data] retain];
}else
{
NSLog(@No network connection available?);
}
}
When I send this all of the data appears as a single string attached to html
variable named ProdName. I suspect this is because all of the data is appended
together. I have tried many variations including dictionaries etc the problem
appears to be that body is NSData and not an Array or collection of some type
which would have made more sense to me. (please correct me if I am wrong in my
thinking) So how do I send multiple pieces of data using POST and have a non
Cocoa aware application separate it at the other end? If some one could assist
me understand how this is supposed to work I would be grateful. Or is
NSURLConnection and NSMutableRequest the wrong set of classes for this purpose?
Regards
Damien

Re: iPhone: load cell from XIB slows down tableview?
John,
I had a similar issue. For me the problem turned out to be that the
reusableId was not being set as it was imported from the nib. Thus the
call dequeue one was always retuning nil. I solved this by building
the cell by hand and calling the correct init method so the reusableid
was being set and all works well now. Let me know if there is a better
solution.

Hello, all ...
I'm trying to determine why my tableviews scroll so jerkily on
non-3GS devices. The datasource only has perhaps 170 records, so I
think it may have something to do with how i'm instantiating the

I create the view for the cell programmatically, and alloc / init
the cell if I can't dequeue it. However, in this app, I have the
cell's view loaded from a XIB. Is there a better way of defining my
cell's view with IB that still results in a performant tableview?
- (UITableViewCell *)tableView:(UITableView *)tableViewIn

extending automatic core data entity classes
Hi All,
I have a problem with core data. Probably caused by my lack of understanding.
Below is the header file for the attribute I am bringing in from core data. I
want to add a convenience method to this class indicated as -
(ADDITIVE_WARNING_TYPE)returnAdditiveWarningByType below.
The issue is when this method is called I get the error below
iPhone Simulator 3.1 (139.1), iPhone OS 3.1.2 (7D11)
*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '*** -[NSManagedObject returnAdditiveWarningByType]: unrecognized
selector sent to instance 0x3a2d580'
It is called like this in the code
AdditiveEntity *additiveEntity = (AdditiveEntity *)[fetchedResultsController
objectAtIndexPath:indexPath];
if ([additiveEntity returnAdditiveWarningByType] ==
ADDITIVE_WARNING_TYPE_WARNING)
{
}
This indicates that despite the fact I have cast the object to an
additiveEntity the class I am trying to apply this to is of type
NSManagedObject not my class at all. So my questions are am I a complete idiot
and have missed something simple? Am I able to add convenience methods to the
classes that core data generates for use as the entity classes if so can
someone tell me what am I doing wrong? Is there something stopping me from
casting the result of [fetchedResultsController objectAtIndexPath:indexPath] to
a AdditiveEntity which is a subclass of NSManagedObject anyway?
This is a very perplexing problem as I am sure it is something dumb I am doing
but can not see it. Thanks in advance for any assistance.
Regards
Damien

Re: [iPhone] Custom UIView like in iPhone Messages App
Tharindu, I did this by subclassing UITableView and overriding - (void) setBackgroundImage:(UIImage*)image This gives me a static background that the tableView will scroll over the top. Next you need to create a custom cell for your messages and pop them into the UItableView subclass in the method - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath Someone will probably correct my approach if it is inefficient or incorrect. I hope this helps. Let me know if you still can not get there.

Search on Core data Table issue?
Hi All, Not sure if this is the right place (I am sure someone will let me know if it is not) I have a iPhone application that has a UITable view that is backed by core data. I want to perform a reducing search so that only the items starting with the characters entered into the search bar are shown. This is normally done with delegate - (void) searchBar:(UISearchBar *)searchBar textDidChange:(NSString *) searchText no problem. I am a little confused as I am new to Core Data how to do this. One of the big problems as I see it is going to be updating the interface to let it know what to present. I assume an alternative NSFetchedResultsController needs to be sent to the UITableView. So here are my issues: 1) I assume I need to create a NSFetchedResultsController with only the correct items in it then tell the UITableView to use this as the dataSource and reload the table? 2) is there a better way than executing a full sorted fetch and removing those objects that do not conform. ie is there a way of doing a select where type fetch?

Programatically selecting items in a NSTableView
Hi All,
I have a NSTableView in a dialogue box (NSPanel subclass) I am passing
in a value that I want to be the item that is selected when the
dialogue opens.
I fully populate the Datasource Array then I do this
//select the item passed in
for(unsigned arrayCounter = 0; arrayCounter [diaMediaItemsArray
count]; arrayCounter++)
{
if([(DCOViewItem *)[diaMediaItemsArray objectAtIndex:arrayCounter]
keyID] == itemToSelect)
{
[diaItemsTableView selectRowIndexes:[NSIndexSet indexSetWithIndex:
(unsigned)arrayCounter] byExtendingSelection:NO];
}
}
This does not work and I was wondering if
1: can I programatically select an item in a NSTableView?
2: have I done something stupid?
3: This is part of the init of the NSPanel subclass should it be
somewhere else (awakeFromNib does not work either).
Thanks
Damien

Re: Transparency with PNG on NSImageView
Thanks David, I am not sure that this will work for me in this instance as the smaller image needs to be in a NSImageView so I can drag n'drop other images in there.

Enum advice please
Hi all,
I have the following code:
typedef enum _DCDBTypes
{
DCOItemType = 0,
DCOCategoryType = 1,
DCORegionType = 2
}DCDBTypes;
It gives me this error message.
error: expected specifier-qualifier-list before 'typedef'
If I try to use it like this
- (void)setItemType:(DCDBTypes) newType;
I get this error message
error: expected ')' before 'DCDBTypes'
I have stared at this piece of code for so long, I know it is
something stupid I have assumed or done, please glance over it and
point me in the right direction if possible.

Thanks, as it turns out if I put it above the @interface statement in
