如何使用 Apple TV 遥控器获取动作事件 [英] How to get motion events with the Apple TV remote

问题描述

有没有人想出如何使用新的 Apple TV 遥控器来处理动作事件?谢谢.

Has anybody figured out how to get motion events working with the new apple TV remote? Thanks.

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!")
}

无论有没有调用 super 都不能给我什么.

With and without calling super gives me nothing.

推荐答案

可以在这里找到一个很好的 swift 示例:https://forums.developer.apple.com/message/65560#65560这基本上就是 Daniel Storm 上面所说的，但是按照这个让它对我有用.这就是我所做的.

A great swift example can be found here: https://forums.developer.apple.com/message/65560#65560 It's basically what Daniel Storm said above, but following this got it working for me. Here's what I did.

在 appDelegate 中:

In appDelegate:

 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  
}  

我希望它实现的地方，就我而言是 SKScene:

Where I want it implemented, in my case an 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)")  
    }  
}
