ios – SpriteKit和UISwipeGestureRecognizer

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)

然后我设置了移动功能：

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'

可能是什么问题呢？

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”.你需要使用“move：”代替.
