什么是Swift相当于UIGestureRecognizerStateEnded？

Question

我正试图检测平移手势何时结束.在Objective-C下,我会做类似以下的事情:

- (void)panGesture:(UIPanGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateEnded) {
        ...
    }
}

在我的Swift项目中,它无法识别UIGestureRecognizerStateEnded......也许我只需要导入不同的东西(？)

Answer 1

相当于

gesture.state == .Ended

或者如果你喜欢

gesture.state == UIGestureRecognizerState.Ended
