iOS 锁屏音频播放控制及音频信息设置

释放双眼,带上耳机,听听看~!

iOS 后台音频播放控制,锁屏音频播放控制及音频信息设,效果图如下:

 

 

1.在 AppDelegate.m 中实现下面方法,获取音频播放、暂停、上一首、下一首点击事件:

- (BOOL)canBecomeFirstResponder
{
return YES;
}
//锁屏界面控制监听
- (void)remoteControlReceivedWithEvent:(UIEvent *)event
{
if (event.type == UIEventTypeRemoteControl) {
switch (event.subtype) {
case UIEventSubtypeRemoteControlPlay:
{
//播放
NSLog(@"Play");
break;
}
case UIEventSubtypeRemoteControlPause:
{
//暂停
NSLog(@"Pause");
break;
}
case UIEventSubtypeRemoteControlNextTrack:
{
//下一首
NSLog(@"Next");
break;
}
case UIEventSubtypeRemoteControlPreviousTrack:
{
//上一首
NSLog(@"Previous");
break;
}
default:
break;
}
}
}

 

2.设置锁屏信息:

//设置锁屏信息
- (void)setLockingInfo
{
Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");
if (playingInfoCenter) {
//音频模型
HWMusicModel *model = [HWMusicTool playingMusic];
//数据信息
NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];
//图片
MPMediaItemArtwork *albumArt = [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageWithUrlString:model.icon]];
[songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
//当前播放时间
[songInfo setObject:[NSNumber numberWithDouble:[[[HWMusicTool shareMusicTool] Player] currentPlaybackTime]] forKey:MPNowPlayingInfoPropertyElapsedPlaybackTime];
//速率
[songInfo setObject:[NSNumber numberWithFloat:1.0f] forKey:MPNowPlayingInfoPropertyPlaybackRate];
//剩余时长
[songInfo setObject:[NSNumber numberWithDouble:[[[HWMusicTool shareMusicTool] Player] duration]] forKey:MPMediaItemPropertyPlaybackDuration];
//设置标题
[songInfo setObject:model.title forKey:MPMediaItemPropertyTitle];
//设置副标题
[songInfo setObject:@"周杰伦 - 周杰伦的床边故事" forKey:MPMediaItemPropertyArtist];
//设置音频数据信息
[[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];
}
}
