Is there a way to change the speed of scrollRectToVisible?

Is there a way to change how quickly scrollRectToVisible animates when scrolling a UIScrollView?

Solution

  • No, not with public methods. The duration is fixed at 0.3 seconds.

    There is a private, undocumented API to change the duration:

    @interface UIScrollView(UIScrollViewInternal)
-(void)_setContentOffsetAnimationDuration:(NSTimeInterval)duration;
@end

    but as all undocumented API, using this will lead to rejection from AppStore.
