在 iOS 设备中以 react-native 播放声音

Question

在我的应用程序中，我有一个功能可以在收到消息时播放声音，它会通过播放声音文件来通知用户，该应用程序使用 react-native-sound 在 Android 中很好，但在 iOS 中我不断收到此错误：

我用于初始化声音的代码：

import Sound from "react-native-sound"

// Load the sound file 'whoosh.mp3' from the app bundle
// See notes below about preloading sounds within initialization code below.
var message_received = new Sound(require("../../res/audio/Page_Turn.mp3"), Sound.MAIN_BUNDLE, (error) => {
    if (error) {
      console.log('failed to load the sound', error);
      return;
    }
    // loaded successfully
    console.log('duration in seconds: ' + message_received.getDuration() + 'number of channels: ' + message_received.getNumberOfChannels());
});

我在初始化声音文件后调用的方法：

message_received.play()

有人知道怎么解决吗？

Answer 1

来自 react-native-sound 文档：

iOS: Open Xcode and add your sound files to the project (Right-click the project and select Add Files to [PROJECTNAME]).

然后就可以调用了

new Sound('Page_Turn.mp3',

Answer 2

如果使用require(filepath)，则不需要Sound.MAIN_BUNDLE，第二个参数是回调：

new Sound(require("../../res/audio/Page_Turn.mp3"), (error) => {})
play函数应该在初始化成功后调用

var message_received = new Sound(require("../../res/audio/Page_Turn.mp3"), (error) => { 如果（错误）{ console.log('failed to load the sound', 错误); return; } //加载成功 message_received.play() });
记得将您的 .mp3 文件添加（引用）到 xcode，重新运行 react-native run-ios。
