Hi,
I'm trying to implement a logging facility for an app that should behave quite
the same as OS X's Console.app in terms of displaying the log, i.e. an
NSTableView with varying row heights. I got it working so far, but there are
major drawing glitches when resizing the window or scrolling
Then the bug is somewhere in your changes. The only thing you
should do is remove the retain calls. If you also remove the
release calls, you will still have the memory leaks.
Here's what openStreams should look like:
- (void)openStreams {
[inputStream setDelegate:self];
[outputStream
I'm trying to calculate the width of a text
Cocoa: NSAttributedString(AppKitAdditions) implements a method named -
size which gives you the size as if the string was drawn with the
attributes set.
Cocoa Touch: NSString(UIStringDrawing) has some methods starting with -

I'm just building my own application based on the CocoaEcho sample
from Apple. But the CocoaEcho Client is full of memory leaks. These
leaks occur, when you select and deselect a CocoaEchoServer some
times by clicking on them and again next to them Leaked Objects are:
SCNetworkReachability
P.S.: I just tested NSGradient's -getColor:location:atIndex: method
(the only one I could find that returns an object by reference) and
here too, the first parameter (an NSColor **) has a retain count of
1 and is not autoreleased.
How do you know that it isn't autoreleased?
I don't know
Sorry about any confusion that I may have caused! The color I got from
the NSGradient's -getColor:location:atIndex: actually was
autoreleased, but the NSGradient was not. Therefore, the color always
had an retain count of 1.
Sorry about that.
If you are trying to find a leak, then use

Hi!
In Quartz Composer, published input ports of type index or number have
a text field and a circular NSSlider in the viewer's parameter panel.
This NSSlider behaves exactly like I would like mine to behave, but I
can't figure out how to do that.

I would like to be able to use an SSL certificate, but, beyond that,
my needs aren't exotic. Ease-of-use and reliability would be a big
plus. I've also considered a Ruby class that would handle the TCP
messaging and pass responses back to the Cocoa-based app. Any
suggestions?
Maybe
Two words. Un Do.
But of course. Thanks.
I don't know how I could not figure that out, considering that I am
disabling enabling the undo manager and grouping actions together in
other parts of my app already.
For future reference:
I want to make a simple filter that takes the output of ls -la and
reformats it to appear more like the MS-DOS directory listing. So, I
would do something like ls -la | mydosfilter and get a directory
listing with the filename first, the # bytes second, then the
timestamp (leaving out
I have a boolean set for my preferences to check whether the user
wants to backup the database at each start. My only question is how
should I do it? I already log whether they want it or not, so I have
got that far.
Should I read the contents of my backup file? How could I find that
So what's the correct form of weak linking to avoid retain cycles?
Please be aware that weak has a different meaning depending on the
context (GC vs non-GC).

Note: In memory management, a nonretained object reference is known as
a weak reference, which is something altogether
but in the above added tableColumn data is not populated and an
opening brace is shown in each row of that column.
To me, this sounds like some data is being read and displayed in the
table, but it's not quite what you want. If you do an NSLog(@%@,
someArray), the -description method will
I'm trying to make a stopwatch application, and I'm having trouble
getting the Timer to fire, and then having the Text field being
updated.
Here's the code:
The essential part is missing: the method in which you are updating
your text field.
- (IBAction)startWatch:(id)sender
{
Thanks. That solved many issues.
However, I still have another question.
How about if I wanted the Timer to start at from 0, and then go to
1, 2, 3, etc..., not from January 1st like -
timeIntervalSinceReferenceDate does? I tried doing
timeIntervalSinceDate:, but it wouldn't work, and
I'm planning on making a stopwatch where the timer fires and then
the text field updates by each second.
I read online that I should use NSTimeInterval for this, as well as
NSDate, and NSTimer.
My main question is, how do you use NSTimeInterval?
NSTimeInterval is just a typedef for
Should I also use NSRunLoop?
Whether you have to do something with run loops depends on what
exactly you want to do. Maybe the default behaviour you get by using
one of the -scheduledTimer... methods is already what you need.
Take a look at the docs for NSTimer and NSRunLoop:

I drag and drop a row from the table view to the textfield.
Now, after drop, i would want to have a database transaction.
I would want to validate the text that i have dropped onto the text

Once it is pushed it stays pushed - pushing it again does not revert
it back to unpushed state.
You could simply hook up an appropriate kind of a standard NSButton to
an IBAction that disables the button. That way, you can't click it
anymore and it stays pushed.

I just added a panel to my program. I do not want that the panel
closes on command-W. I did setBecomesKeyOnlyIfNeeded:YES. So It does
not close if there is a document window. But if the last one is
closed (with keyboard: command-W) also the panel closes.
I'm taking a stab in the dark here,
