Delimit UISwipeGestureRecognizer

Question

有一种方法可以仅在特定项目上划分滑动吗？

以这种方式随处可见

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];

谢谢！

Answer 1

您可以将滑动识别器仅添加到要滑动的视图中。或者，你可以这样做：

swipeRightRecognizer.delegate = self;
//...


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