double free error
I was receiving malloc double free errors when a view removed itself, so all
of the releases I was doing in the view I commented out, the view killing
itself after it animates from visual view:
- (void) killMe:(NSString *)animationID finished:(NSNumber *)finished
context:(void *)context {
[self.view removeFromSuperview];
}
I no longer receive the malloc double free errors. I was creating NSStrings
and NSDateFormatters (init type stuff), all of which I previously was
releasing myself. Does it sound reasonable that the removeFromSuperview was
cleaning all that up already and thus the releases caused the errors? I am
trying to still get my head around memory management.
Thanks,
Eric

removeFromSuperview
Unlinks the receiver from its superview and its window, and removes it from the
responder chain.
- (void)removeFromSuperview
Discussion
If the receiver’s superview is not nil, this method releases the receiver.

If you plan to reuse the view, be sure to retain it before calling this method
and be sure to release it as appropriate when you are done with it or after
adding it to another view hierarchy.
