在 Apple Watchkit 中播放声音
Playing sound in Apple Watchkit
我正在尝试使用 WKAudioFilePlayer 通过 watchkit 扩展播放声音,但是没有播放任何声音。我正在使用触觉反馈代码作为一种调试,以确保它执行它(它确实执行了)。作为旁注,静音未打开且文件名正确。
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];
我按如下方式实现,效果很好。 (抱歉,是 Swift)
1) 为玩家对象定义一个属性
var player: WKAudioFilePlayer!
2) 唤醒时设置资产和播放器
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) 如果玩家准备好玩就玩。
@IBAction func playBtnTapped() {
switch player.status {
case .ReadyToPlay:
player.play()
case .Failed:
print("failed")
case .Unknown:
print("unknown")
}
}
此外,需要连接一个蓝牙耳机和watch。
