ionic 实现音乐后台播放

要实现ionic 音乐后台播放要完成两个步骤。

• 在xcode中的info.plist开启Required background modes 数值设置为 数组 App plays audio or streams audio/video using AirPlay
• 修改AppDelegate.m文件为如下：

#import "AppDelegate.h"#import "MainViewController.h"#import <AVFoundation/AVFoundation.h>@implementation AppDelegate- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions{    AVAudioSession *audioSession = [AVAudioSession sharedInstance];    BOOL ok;    NSError *setCategoryError = nil;    ok = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];    self.viewController = [[MainViewController alloc] init];    return [super application:application didFinishLaunchingWithOptions:launchOptions];}@end
