Question

Working with an array of UIViews and UIImageViews ([[[UIApplication sharedApplication] window] subviews]). I need to remove only the object of the highest index of the UIImageView type.

Answer 1

another block-based solution

[window.subviews enumerateObjectsWithOptions:NSEnumerationReverse 
                                  usingBlock:^(id view, NSUInteger idx, BOOL *stop) 
    {
        if ([view isKindOfClass:[UIImageView class]]){
            [view removeFromSuperview];
            *stop=YES;
    }
}];

non-block solution:

for (UIView *view in [window.subview reverseObjectEnumerator])
{
    if ([view isKindOfClass:[UIImageView class]]){
            [view removeFromSuperview];
            break;
    }
}

I published some demo code, that shows both solutions.
