Question

For example, I have a button, when click this button, it call an action: doAction1.
And an View: when touch in it, it call an action doAction2.

When clicked in this button, I touched in view, too.
Is it have any property to set priority to call doAction1 or doAction2?

I assume that you you put a Tapgesturerecogniyer to container view.You can ignore the tap gesture if user has tapped on the button.Just overwrite the fooling method

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
// test if touched view is unbutton

    if ([touch.view isKindOfClass:[UIButton class]]) 
    {

        return NO; // ignore the touch
    }

return YES; 

}
