Question

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    NSLog(@"will rotation");

    for (UIButton *button in self.view.subviews) {
        [button removeFromSuperview];
    }

}

I have a problem with this code. I need to remove only UIButtons from my view. But this code also remove all subviews of my self.view. How can I solve this?

Answer 1

Do this:

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
NSLog(@"will rotation");

   for (id subview in self.view.subviews) {
    if([subview isKindOfClass:[UIButton class]]) //remove only buttons
    {
      [subview removeFromSuperview];
    }
   }

}
