iPhone-Development - EXC_BAD_ACCES after UIView beginAnimations -> didStopSelector
    [UIView beginAnimations:nil context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(scrollViewScrolled)];
    
[scrollView setContentOffset:scrollToPosition];

[UIView commitAnimations];

//////////////////////////

- (void)scrollViewScrolled {
    [self putScreenShotToScrollView];
    [self loadImageStack];
}

//////////////////////////

- (void)putScreenShotToScrollView {
    UIImageView *scrollViewScreenShotView;

    float scrollViewScreenShotPositionX;
    float scrollViewScreenShotPositionY;
    CGRect scrollViewScreenShotFrame;
    
    scrollViewScreenShotView = [[UIImageView alloc] initWithImage:usedImageStack.screenShot];
    // So, always when the app try to access the usedImageStack.screenShot the exception EXC_BAD_ACCES determines the app
    // usedImageStack and the property screenShot have an address, so not 0x0
}

Do you know what's the problem?

Thanks!
