UITableView/UIScrollView 不能响应TouchBegin 的处理 及窥见 hitTest:withEvent：

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    
    static UIEvent *e = nil;
    
    if (e != nil && e == event) {
        e = nil;
        return [super hitTest:point withEvent:event];
    }
    
    e = event;
    
    if (event.type == UIEventTypeTouches) {
        NSSet *touches = [event touchesForView:self];
        UITouch *touch = [touches anyObject];
        if (touch.phase == UITouchPhaseBegan) {
            NSLog(@"Touches began");
        }else if(touch.phase == UITouchPhaseEnded){
            NSLog(@"Touches Ended");

        }else if(touch.phase == UITouchPhaseCancelled){
            NSLog(@"Touches Cancelled");

        }else if (touch.phase == UITouchPhaseMoved){
            NSLog(@"Touches Moved");

        }
    }
    return [super hitTest:point withEvent:event];
}
