在Apple Watchkit中播放声音

本文介绍了在Apple Watchkit中播放声音的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试使用WKAudioFilePlayer通过watchkit扩展播放声音但是没有播放声音。我正在使用触觉反馈代码作为一种调试来确保它执行它（它做了）。作为旁注，静音未打开且文件名正确。

I'm trying to play a sound through the watchkit extension using WKAudioFilePlayer however no sound gets played. I'm using the haptic feedback code as a sort of debug to be sure it executes it (which it does). As a side note, mute is not on and the filename is correct.

NSURL *falcon = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"falcon" ofType:@"mp3"]]; WKAudioFileAsset *asset = [WKAudioFileAsset assetWithURL:falcon]; WKAudioFilePlayerItem *sound = [WKAudioFilePlayerItem playerItemWithAsset:asset]; audioPlayer = [WKAudioFilePlayer playerWithPlayerItem:sound]; [audioPlayer play]; WKInterfaceDevice *device = [WKInterfaceDevice currentDevice]; [device playHaptic:WKHapticTypeClick];

推荐答案

我实现如下，它工作正常。 （对不起，这是Swift）

I implemented as follows and it worked fine. (Sorry, it's Swift)

1）为玩家对象定义一个属性

1) Define a property for the player object

var player: WKAudioFilePlayer!

2）在资产和玩家醒来时设置资产和玩家

2) Setup the asset and player when it's awaking

override func awakeWithContext(context: AnyObject?) { super.awakeWithContext(context) let filePath = NSBundle.mainBundle().pathForResource("se_tap", ofType: "m4a")! let fileUrl = NSURL.fileURLWithPath(filePath) let asset = WKAudioFileAsset(URL: fileUrl) let playerItem = WKAudioFilePlayerItem(asset: asset) player = WKAudioFilePlayer(playerItem: playerItem) }

3）如果玩家准备好玩 。

3) Play if the player is ready to play.

@IBAction func playBtnTapped() { switch player.status { case .ReadyToPlay: player.play() case .Failed: print("failed") case .Unknown: print("unknown") } }

此外，还需要连接蓝牙耳机用watch。

In addition, it needed to connect a Bluetooth Headset with watch.
