I'm using this block to animate a pulse on my text and when I do, the text moves to the right some and jerks back. Seems like it is due to some padding or something being added by interface builder. 

```
[UIView animateWithDuration:0.5 animations:^{
    // grow the label up to 130%, using a animation of 1/2s
    myLabel.transform = CGAffineTransformMakeScale(1.3,1.3);
} completion:^(BOOL finished) {
    // When the "grow" animation is completed, go back to size 100% using another animation of 1/2s
    [UIView animateWithDuration:0.5 animations:^{
        myLabel.transform = CGAffineTransformIdentity;
    }];
}];

```
