Here you are creating a pointer to an empty string. This consumes memory.

I'm sure you are correct.

I don't know but it annoyed us at SeatMe. Apple stole our SM prefix for
ServiceManagement.framework in 10.6 and we banged into a few classes.
We need namespacing in Cocoa so bad.

If you are going to assign another value to 'theString' before you use it, then
doing this is pointless.

I usually use the sample in line 1 when declaring vars inside my methods.
NSString *theString = [NSString string];
NSString *theString = nil;
NSString *theString;
I thought lines 2 and 3 were the same thing. I was wrong. What is the
difference and when do you use the style shown in line 3?

Hello,
I would also profile it with the Core Animation instrument. Make sure you
select the "Color Blended Layers" checkbox in the Debug Options area. This will
apply a colored overlay to each view (green is opaque and red is transparent.)

I wonder if someone could point me to the right way to profile
poorly-performing custom-drawn UITableView cells. I've come across this problem
several times, and usually manage to figure out how to solve it, but my process
is not very scientific—there's far too much trial and error involved, and
Does anyone out there use SMJobBless to interact with the Mac OS X to
create/destroy, and load/unload launchdamons/agents?
Really looking for sample code to make sure I'm doing things
correctly...sometimes my jobs go wonky.
Apple docs have not been updated in about 2 years time...
Thanks,

Hello,
I'm posting this here because quartz-dev seems dead. I have a layer
hosting view where I use a -compositingFilter with a CIColorBlendMode
filter (default settings). It's constructed and applied to the layer
like this:
CIFilter *cf = [CIFilter filterWithName:@"CIColorBlendMode"];
Thanks for replying,
to tell you the truth I thought of this before the post and i tried using
[view performSelectorOnMainThread:@selector(remove_view:) withObject:nil
waitUntilDone:YES];
where remove_view method calls 'removefromsuperview' however the application
still came to a Not Responding
I wonder if you should move that removeFromSuperview back onto the main thread?
I know when I was doing lots of cross language stuff with java in the past that
that was usually my problem.

I've had a similar problem to this in the past. I never bottomed it out.
The workaround I used was to check validity of the row index for every data
call and, if the index was invalid, return a
suitable easily visible debug string ( "bad index") and post a timed update
0.25 second later.

Dear Peter,
Thank you for your reply. Here is the requested code (see below).
After more investigations, I would like to take back a previous statement, that
the tableview was perfectly aware that the number of rows in the DS was
changed. This is due to my inexperience in stepping through the c
Can you post your code for numberOfRowsInTableView:

Hi,
I am currently working on making an iOS browser which will have
provision to set proxy in it. I am making browser as wrapper around
UIWebview. But as NSURL / NSREQUEST doesn't support setting proxy, so
I got struck here. I know that we can set proxy in CFURL, so is there
any way we can capture
