Question

I have some animation that does some rotation using beginAnimations.
I want to hide the UIview in question, of course I tried changing the hidden property but nothing happened.
Here is the code

 CGAffineTransform rotation = CGAffineTransformMakeRotation( angelToRotate(-90));
[UIView beginAnimations: @"" context: NULL];
self.view.hidden = TRUE;
[UIView setAnimationDuration: 0.4];
self.view.transform = CGAffineTransformConcat(self.view.transform, rotation);
self.view.hidden = FALSE;
[UIView commitAnimations];

I also tried changing the alpha on the view, but still nothing.

Any ideas?

Answer 1

CGAffineTransform rotation = CGAffineTransformMakeRotation( angelToRotate(-90));   
[UIView animateWithDuration:0.4 animations:^
{
    self.view.transform = CGAffineTransformConcat(self.view.transform, rotation);
    self.view.alpha = 0.0;
}
completion:^(BOOL finished)
{
    self.view.alpha = 1.0;
}];

Or:

---

CGAffineTransform rotation = CGAffineTransformMakeRotation( angelToRotate(-90));
[UIView beginAnimations:nil context: NULL];
[UIView setAnimationDuration:0.4];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
self.view.transform = CGAffineTransformConcat(self.view.transform, rotation);
self.view.alpha = 0.0;
[UIView commitAnimations];

---

- (void) animationDidStop: (NSString *) animationID finished: (NSNumber *) finished context: (void *) context
{
    self.view.alpha = 1.0;
}
