Ummm, is this really hard?

You can't pass a method so you'll have to write a C function as your callback
function. If the library allows you to pass a parameter to the function which
will be in turn passed to the callback, then you would pass your view
controller to the function and then call the method from the function.

I have been experimenting with the new iOS 4 block-based UIView animation,
and I cannot find any situation where the option
UIViewAnimationOptionAllowAnimatedContent makes any difference. What I
expect from the documentation is that this should cause drawRect: to be
called repeatedly, but it doesn'

Many thanks for the reply, much appreciated. I figured the "re-entry" probably

Hi,
I've got a lot of code that depends on 10.6's use of NSView's animator and
setAlphaValue for showing and hiding animations. Now, i need to bring this to
10.5. On 10.5, to animate the alphaValue, i learnt that the NSView needs to be
backed by a layer. I tried doing that and it created mayhem
The iOS 4 syntax for using Objective-C blocks with UIView animation (instead
of the old-style UIView "animation block", love the confusing terminology
here) is delightful, but some features are missing:
* You can't designate a delegate, so you can't get a notification when the
animation is about t
That usually means drawRect: is being called while the table is already inside
its own drawRect: method.
I've had to deal with this recently. One possible way to find out where it's
happening is to subclass your table view and override drawRect:, then setup a
counter to check to see if the re-e

Hello,
I have an NSOutlineView with variable row heights, as determined in

Hello,
This problem was introduced in Mac OS X 10.6 and has remained unsolved
ever since.
I've got a timer that polls iTunes for its player position every
second. I used to use ScriptingBridge for this task:
if ( [iTunes isRunning] ) {
if ( [self isPlaying] ) return [iTunes playerPosition];
}
