android - Cordova + iOS-当应用程序在后台运行时如何播放音频文件？

Question

我有正在播放选定声音的Cordova应用程序。我想在用户离开应用程序并且另一个即将到来时继续播放声音。

在iOS平台上我该怎么做？在Android上，默认情况下可以正常运行。

非常感谢您的任何建议。

更新:

我做了以下事情:

plist.info

<plist version="1.0">
  <dict>
    <string>UIBackgroundModes</string>
    <key>audio</key>

AppDelegate.m

/**
 * This is main kick off after the app inits, the views and Settings are setup here. (preferred - iOS4 and up)
 */
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    BOOL ok;
    NSError *setCategoryError = nil;
    ok = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];
    CGRect screenBounds = [[UIScreen mainScreen] bounds];

但结果相同。

Answer 1

首先，做那些我在this question中写的东西。然后将AVFoundation导入您的AppDelegate.m #import <AVFoundation/AVFoundation.h>
然后将以下内容添加到application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
BOOL ok;
NSError *setCategoryError = nil;
ok = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];

和

TEST IN REAL DEVICE, NOT IN SIMULATOR. BACKGROUND AUDIO DOESN'T WORK WITH SIMULATOR.
