分隔UISwipeGestureRecognizer

Question

有没有办法只在一个特定的项目上划线？

通过这种方式，它在任何地方都可以工作。

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

您可以将卷帘识别器仅添加到要卷帘的视图。或者，您可以这样做：

swipeRightRecognizer.delegate = self;
//...


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