ios - 如何以编程方式设置 UIGestureRecognizer 的状态？

Question

我使用 UIGestureRecognizer:

panGestureRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)];
panGestureRecognizer.delegate = self;

现在，我希望能够将 GestureRecognizer 的状态设置为 UIGestureRecognizerStateEnded，这样当我输入时

- (void)foldToGallery:(UIPanGestureRecognizer*)gesture

它将执行下面的代码:

if (gesture.state == UIGestureRecognizerStateEnded

并忽略其余的手势，直到我开始一个新的手势

Answer 1

也许你可以设置gesture.enabled = NO
这将导致状态 `UIGestureRecognizerStateCancelled ( documentation )。也许您可以检查此状态并在之后再次启用它。
