Please help my animation is not working ios

I have an issue. I'm using animation block, but the second animation simultaneously animates with the first animation.

This is my code.

[UIView animateWithDuration:2.0f
                      delay:0.0f
                    options:UIViewAnimationOptionCurveEaseOut
                 animations:^{
                     self.scrollView.frame = CGRectMake(63, 59, 437, 289);
                 }
                 completion:^(BOOL finished){
                     if (finished) {
                         [UIScrollView beginAnimations:nil context:NULL];
                         [UIScrollView setAnimationDuration:0.6];
                         self.scrollView.frame = CGRectMake(63, 2, 437, 289);
                         [UIScrollView commitAnimations];
                     }
                }]

Thanks in advance..

Add an NSLog that displays self.scrollView.frame before the first animation. If you don't actually change anything in an animation, I think it will just get skipped.

Maddy told you what to do. The nested block syntax can be hard to figure out, so cheat:

[UIView animateWithDuration:2.0f
                      delay:0.0f
                    options:UIViewAnimationOptionCurveEaseOut
                 animations:^{
                     self.scrollView.frame = CGRectMake(63, 59, 437, 289);
                 }
                 completion:^(BOOL finished){
                     if (finished) 
                     {
                         [self secondAnimation];
                     }
                }]


- (void) secondAnimation:
{
  [UIView animateWithDuration: 0.6
    animations: ^
    {
      self.scrollView.frame = CGRectMake(63, 2, 437, 289);
    }
  ];
}
