Swift2 如何在攻丝对象上运行操作而不是释放攻丝?
这里是一个简化的scenekit船的默认场景。轻触飞船,释放,飞船旋转。您如何修改程序,以便在点击船舶时启动操作?不用担心松开或按住水龙头Swift2 如何在攻丝对象上运行操作而不是释放攻丝?,swift2,uikit,Swift2,Uikit,这里是一个简化的scenekit船的默认场景。轻触飞船,释放,飞船旋转。您如何修改程序,以便在点击船舶时启动操作?不用担心松开或按住水龙头 class GameViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let scene = SCNScene(named: "art.scnassets/ship.scn")! let cameraNode = SC

手势识别器识别整个手势。对于触碰开始和触碰结束事件在近距离发生时发生的触碰。只有在“轻触手势”完成且两个事件都完成后,内置识别器才会触发 如果您希望在触摸开始或触摸结束时有不同的行为,则必须自己处理低级事件。为此,您可以创建自己的自定义
UIGestureRecognitor
,也可以创建自定义UIView并使用UIResponder
中的方法,如
触摸已开始(:withEvent:)
我不清楚你在问什么。运行此代码的结果是什么?它与您希望发生的情况有何不同?此代码当前在从对象(船)释放点击时调用操作。我想知道启动点击时如何调用动作。您可以参考自定义手势并使用它。感谢您的帮助Scott和chancyWu。
