Hi all, I have two functions increase and decrease which control the number of sides of a polygon. I want to call a - (void)function that disables the buttons if the current number of sides are equal to the maximum number of sides. 1) One problem is that "button.enabled=YES/NO" does not get cal

Re: NSTimer never being deallocated

Hi Paul, You said 'an object you don't manage' -- If I alloc/init an instance of NSTimer I am responsible for this object, in my opinion. That's why I tried to do everything properly. You see I am actually really just trying to prevent memory leaks and I see lots of leaks in sample code I a

Re: death in dealloc

This is almost always caused by releasing an object earlier than you expected to, and then trying to release it again later (similar to "double free"). Look around in your class's code for a place where you autorelease an ivar, but don't add it to a collection, or where you release an ivar but don'

Re: NSTimer never being deallocated

I don't understand all the confusion on this issue. The NSTimer documentation makes the life-cycle of this object very clear. Until it goes away, it is probably retained by the runloop. As Joar says, you often can't make any concrete predictions about when an object you don't manage yourself m

Re: NSTimer never being deallocated

I haven't followed this whole thread, but my experience is that an NSTimer (especially a repetitive one) is an easy thing to leak, even in a GC environment (which I use). To prevent it, you have to make sure you keep a reference to the timer so that you can actually invalidate it, taking it out of

Re: NSTimer never being deallocated

For the benefit of the OP, according to the docs (and this fits in with my own experience), calling [NSTimer invalidate] will release the timer at some future point in the run loop and is in fact the only way to get rid of it. So there is really nothing to worrry about. Trust in Papa Cocoa, al

I have some code that is throwing EXC_BAD_ACCESS. It does so when an object is deallocating, in its -dealloc method on a call to [super dealloc]. The object's class's superclass is NSObject. Here's the (relevant part of the) stack trace: #0 0x7fff872e016d in _class_hasCxxStructorsNoSuper #1
