Removing a view from it's superview causes memory error - why?
- by mystify
Xcode is throwing an error at me:
malloc: * error for object
0x103f000: pointer being freed was not
allocated
* set a breakpoint in malloc_error_break to debug
I tracked down the code until a line where I do this:
- (void)inputValueCommitted:(NSString *)animationID finished:(BOOL)finished context:(void *)context {
// retainCount of myView is 2! (one for the retain-property, one for beeing a subview)
[self.myView removeFromSuperview]; // ERROR-LINE !!
self.myView = nil;
}
When I remove that errorful line, the error is gone. So in conclusion: I can't get rid of my view!
It's an UIImageView with nothing else inside, just showing an image. What I do is this: I create an UIView Animation Block, create that UIImageView, assign it to an retain-property with self.myView = ..., and after the animation is done, I just want to get rid of that view. So I remove it from it's superview and then set my property to nil, which lets it go away - in theory.
Did anyone else encounter such issues? iPhone SDK 3.0.
