播放Apple Watch扬声器的声音

Question

有没有办法从Apple Watch的扬声器中播放声音？我无法在线找到任何文档.

Answer 1

现在可以在watchOS 2中使用WKAudioFilePlayer或使用WKInterfaceMovie.

NSURL *assetURL = [[NSBundle mainBundle] URLForResource:@"file" withExtension:@"wav"];

WKAudioFilePlayer 例:

WKAudioFileAsset *asset = [WKAudioFileAsset assetWithURL:assetURL];
WKAudioFilePlayerItem *playerItem = [WKAudioFilePlayerItem playerItemWithAsset:asset];
WKAudioFilePlayer *audioFilePlayer = [WKAudioFilePlayer playerWithPlayerItem:playerItem];
[audioFilePlayer play];

WKInterfaceMovie 例:

[self presentMediaPlayerControllerWithURL:assetURL options:nil completion:nil];

Answer 2

import AVFoundation
var player: AVAudioPlayer?

if let path = Bundle.main.path(forResource: "siren", ofType: "wav") {

        let fileUrl = URL(fileURLWithPath: path)

        do{
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
            try AVAudioSession.sharedInstance().setActive(true)

            player = try AVAudioPlayer(contentsOf: fileUrl)

            guard let player = player else { return }

            player.play()

        }
        catch
        {

        }

    }

我用它从 Apple Watch(4.3) 扬声器播放自定义声音并且工作得很好。不要忘记将音频文件目标成员资格设置为手表套件。
