iOS中关于音乐锁屏控制音乐(锁屏信息设置)的实例代码
废话不多说了，直接给大家贴代码了，具体代码如下所示：
<prename="code"class="objc">appDelegate里面加入如下代码获取后台播放权限</pre><prename="code"class="objc">-(void)setAudioBackstagePlay{
AVAudioSession*audioSession=[AVAudioSessionsharedInstance];
[audioSessionsetCategory:AVAudioSessionCategoryPlaybackerror:nil];
[audioSessionsetActive:YESerror:nil];
}</pre>
<pre></pre>
<prename="code"class="objc">//重写父类方法，接受外部事件的处理
-(void)remoteControlReceivedWithEvent:(UIEvent*)receivedEvent{
NSLog(@"remote");
if(receivedEvent.type==UIEventTypeRemoteControl){
switch(receivedEvent.subtype){//得到事件类型
caseUIEventSubtypeRemoteControlTogglePlayPause://暂停ios6
[_playermusicPause];//调用你所在项目的暂停按钮的响应方法下面的也是如此
break;
caseUIEventSubtypeRemoteControlPreviousTrack://上一首
[selflastMusic];
break;
caseUIEventSubtypeRemoteControlNextTrack://下一首
[selfnextMusic];
break;
caseUIEventSubtypeRemoteControlPlay://播放
[_playermusicPlay];
break;
caseUIEventSubtypeRemoteControlPause://暂停ios7
[_playermusicPause];
break;
default:
break;
}
}
}</pre><prename="code"class="objc"><prename="code"class="objc">-(void)configNowPlayingCenter{
NSLog(@"锁屏设置");
