有没有人想出如何使用新的 Apple TV 遥控器来获得运动事件？谢谢。

我试过打电话

override func motionBegan(motion: UIEventSubtype, withEvent event: UIEvent?) {
    super.motionBegan(motion, withEvent: event)
    print("motion!")
}
override func motionEnded(motion: UIEventSubtype, withEvent event: UIEvent?) {
    super.motionEnded(motion, withEvent: event)
    print("motion ended!")
}

无论是否调用 super 都没有给我任何东西。

可以在这里找到一个很好的 swift 示例： https ://forums.developer.apple.com/message/65560#65560 这基本上是 Daniel Storm 上面所说的，但之后它对我有用。这就是我所做的。

在 appDelegate 中：

 var motionDelegate: ReactToMotionEvents? = nil   

     func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {  
        let center = NSNotificationCenter.defaultCenter()  
        center.addObserver(self, selector: "setupControllers:", name: GCControllerDidConnectNotification, object: nil)  
        center.addObserver(self, selector: "setupControllers:", name: GCControllerDidDisconnectNotification, object: nil)  
        GCController.startWirelessControllerDiscoveryWithCompletionHandler { () -> Void in  

        }  
        return true  
    }  

    func setupControllers(notif: NSNotification) {  
        print("controller connection")  
        let controllers = GCController.controllers()  
        for controller in controllers {  
            controller.motion?.valueChangedHandler = { (motion: GCMotion)->() in  
                if let delegate = self.motionDelegate {  
                    delegate.motionUpdate(motion)  
                }  
            }  
        }  
    }  

protocol ReactToMotionEvents {  
    func motionUpdate(motion: GCMotion) -> Void  
}

我希望它在哪里实现，在我的例子中是一个 SKScene：

import SpriteKit  
import GameController  
class GameScene: SKScene, ReactToMotionEvents {  

    override func didMoveToView(view: SKView) {   
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate  
        appDelegate.motionDelegate = self  

    }  

    func motionUpdate(motion: GCMotion) {  
        print("x: \(motion.userAcceleration.x)   y: \(motion.userAcceleration.y)")  
    }  
}

以为我会用 Swift 4.0 语法更新 CodyMace 的最佳答案

在 appDelegate 中（您也需要在此处导入 GameController）：

var motionDelegate: ReactToMotionEvents? = nil


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    let center = NotificationCenter.default
    center.addObserver(self, selector: #selector(setupControllers), name: NSNotification.Name.GCControllerDidConnect, object: nil)
    center.addObserver(self, selector: #selector(setupControllers), name: NSNotification.Name.GCControllerDidDisconnect, object: nil)
    GCController.startWirelessControllerDiscovery { () -> Void in

    }
    return true
}

@objc func setupControllers(notif: NSNotification) {
    print("controller connection")
    let controllers = GCController.controllers()
    for controller in controllers {
        controller.motion?.valueChangedHandler = { (motion: GCMotion)->() in
            if let delegate = self.motionDelegate {
                delegate.motionUpdate(motion: motion)
            }
        }
    }
}

协议保持不变

protocol ReactToMotionEvents {
func motionUpdate(motion: GCMotion) -> Void

}

以及您想要实施的地方

import SpriteKit  
import GameController  
class GameScene: SKScene, ReactToMotionEvents {  

    override func didMoveToView(view: SKView) {   
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.motionDelegate = self

    }  

    func motionUpdate(motion: GCMotion) {  
        print("x: \(motion.userAcceleration.x)   y: \(motion.userAcceleration.y)")  
    }  
}

通过如何访问遥控器的运动和方向信息：

首先，需要使用NSNotificationCenter来找到控制器。可能最好在应用启动时执行此操作。像这样的东西：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(controllerDidConnect:) name:GCControllerDidConnectNotification object:nil];

然后我们可以在连接后使用以下代码将设备信息存储在属性中：

- (void)controllerDidConnect:(NSNotification *)notification {  
    self.myController = notification.object;  
}

远程配置文件是微型游戏手柄配置文件的子类。可以通过添加值更改事件处理程序来跟踪运动和其他数据：

  GCMicroGamepad *profile =  self.myController.microGamepad  
  profile.valueChangedHandler= ^ (GCMicroGamepad *gamepad, GCControllerElement *element) {  
        if (self.myController.motion) {  
            NSLog(@"motion supported");  
            NSLog(@"gravity: %f %f %f", self.myController.motion.gravity.x, self.myController.motion.gravity.y, self.myController.motion.gravity.z);  
            NSLog(@"userAcc: %f %f %f", self.myController.motion.userAcceleration.x, self.myController.motion.userAcceleration.y, self.myController.motion.userAcceleration.z);  
            NSLog(@"rotationRate: %f %f %f", self.myController.motion.rotationRate.x, self.myController.motion.rotationRate.y, self.myController.motion.rotationRate.z);  
            NSLog(@"attitude: %f %f %f %f", self.myController.motion.attitude.x, self.myController.motion.attitude.y, self.myController.motion.attitude.z, self.myController.motion.attitude.w);  
        }  
    };
