Delimit UISwipeGestureRecognizer

Question

有一種方法只能在特定項目上劃過滑動界限？

這樣它的工作原理無處不在

UIGestureRecognizer *recognizer; 

//RIGHT 
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRight:)]; 
self.swipeRightRecognizer =(UISwipeGestureRecognizer *)recognizer; 
swipeRightRecognizer.direction = UISwipeGestureRecognizerDirectionRight; 

[self.view addGestureRecognizer:swipeRightRecognizer]; 
self.swipeRightRecognizer = (UISwipeGestureRecognizer *)recognizer; 
[recognizer release]; 

的感謝！

Answer 1

您可以將滑動識別器添加到您想要滑動的視圖。或者，你可以這樣做：

swipeRightRecognizer.delegate = self; 
//... 


- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer 
     shouldReceiveTouch:(UITouch *)touch { 
    return (touch.view == myViewThatShouldReceiveSwipes); 
}
