如何在不取消触摸的情况下启动动画？

Question

I have a UIView nested in a UIView . When I animate the frame and alpha of the inner view, touches in the outer view get canceled. Can I stop that from happening?

Answer 1

You can use block based animation methods.

[UIView animateWithDuration:1.0 
     delay:0.0 
     options:UIViewAnimationOptionAllowUserInteraction
                   | UIViewAnimationOptionCurveEaseInOut 
     animations:^{
          //your animation code
     } completion:^(BOOL finished){
          //your code when animation finished..
}];
