title: animateWithDuration setFrame not working
body: <p>Hi I have piece of code which only one line is not working...</p>
  
  <pre><code>[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{
      [label setFrame:CGRectMake(0, 0, frame.size.width, kStandardLabelHeight)]; //working
      [self.currentLabel setFrame:CGRectOffset(self.currentLabel.frame, frame.size.width, 0)]; //not working 
      [self.currentLabel setAlpha:0.0f]; //working
  } completion:^(BOOL finished) {
      [self.currentLabel removeFromSuperview];
      self.currentLabel = label;
  }];
  </code></pre>
  
  <p>I'm running out of ideas what is wrong...</p>
