ios - SpriteKit 和 UISwipeGestureRecognizer

Question

在我的 viewDidLoad 函数中，我设置了一个滑动手势识别器:

var swipeRecognizer:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("move"))
swipeRecognizer.direction = .Right
view.addGestureRecognizer(swipeRecognizer)

然后我设置移动函数:

func move(swipe:UISwipeGestureRecognizer) {
    NSLog("swiped")
}

但是，当我向右滑动时，我不断收到以下错误:

[_TtC8swiftris9GameScene move]: unrecognized selector sent to instance 0xc81c200
2014-06-03 14:52:57.560 swiftris[45440:6777826] 
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '-[_TtC8swiftris9GameScene move]: unrecognized selector sent to instance 0xc81c200'

可能是什么问题？

Answer 1

您将函数定义为 move(swipe:UISwipeGestureRecognizer)，它映射到 obj-c 方法名称 move:，但您的选择器只是 "移动”。您需要改用 "move:"。
