How to let a view rotate forever?

Question

Is there a way to let a view rotate forever, with an specified speed? I need that for an indicator kind of thing. I know there is this weird Lxxxxx00ff constant (don\'t reme

Answer 1

my bet is:

-(void)animationDidStopSelector:... {
  [UIView beginAnimations:nil context:NULL];
  // you can change next 2 settings to setAnimationRepeatCount and set it to CGFLOAT_MAX
  [UIView setAnimationDelegate:self];
  [UIView setAnimationDidStopSelector:@selector(animationDidStopSelector:...)];
  [UIView setAnimationDuration:...

  [view setTransform: CGAffineTransformRotate(CGAffineTransformIdentity, 6.28318531)];

  [UIView commitAnimations];
}

//start rotation
[self animationDidStopSelector:...];

ok better bet:

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationRepeatCount: CGFLOAT_MAX];
[UIView setAnimationDuration:2.0f];

[view setTransform: CGAffineTransformMakeRotation(6.28318531)];

[UIView commitAnimations];
