即使按下按钮子视图，如何使滚动视图滚动

Question

There are countless questions about UIScrollView s, touch events and subviews, but I couldn't find one that solved my dilemma. I have a UIScrollView with delayed and cancellable content touches in which I have added UIButton s. I can scroll the view wherever I touch (including the buttons), but if my finger lingers on a button for too long, it registers as touching the button, as I want and is expected. However, if I then move my finger as if trying to scroll, the scroll view does not scroll - how can I make it do so? The basic effect I am trying to achieve is like a UITableView handles touches for the cells.

Thanks for your help.

Try implementing the following in your UIScrollView subclass:

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {   
    return YES;
}
