Question

In my app, I have a scrollview with “paging enabled” and when I chose a page an imageview start its animation in this way

- (void) beginWinAnimation{
[UIView animateWithDuration:2.5
                 animations:^{successView.alpha = 1.0;}
                 completion:^(BOOL finished){ 

                 [UIView animateWithDuration:2.5
                 animations:^{successView.alpha = 0;}];
                 }];}

During this animation I can see the scrollview under this successView and I can move scrollview page; I want that during animation you can’t move the scrollview but only when animation is finished, is it possible?

Yes it’s possible. When the animation starts set [scrollView setScrollEnabled:NO]; After your animation is complete set it back to YES.

So in your code, it will look like –

- (void) beginWinAnimation{

[scrollView setScrollEnabled:NO];

[UIView animateWithDuration:2.5
                 animations:^{
                     successView.alpha = 1.0;
                 }
                 completion:^(BOOL finished){ 
                     [UIView animateWithDuration:2.5
                         animations:^{successView.alpha = 0;}
                         completion:^(BOOL finished){ 
                             [scrollView setScrollEnabled:YES];
                         }]; 
                 }];}

See if this works.
