[[avaudiosession sharedinstance] setcategory:avaudiosessioncategoryplayback error:nil];
// 设置播放器
nsurl *url = [nsurl fileurlwithpath:[[nsbundle mainbundle] pathforresource:@ "那些花儿" oftype:@ "mp3" ] ];

//后台播放显示信息设置
[self setplayinginfo];
}

- ( void )remotecontrolreceivedwithevent:(uievent *)event {
if (event.type == uieventtyperemotecontrol) { //判断是否为远程控制
switch (event.subtype) {
case uieventsubtyperemotecontrolplay:
if (!_isplayingnow) {
[_player play];
}
_isplayingnow = !_isplayingnow;
break ;
case uieventsubtyperemotecontrolpause:
if (_isplayingnow) {
[_player pause];
}
_isplayingnow = !_isplayingnow;
break ;
case uieventsubtyperemotecontrolnexttrack:
nslog(@ "下一首" );
break ;
case uieventsubtyperemotecontrolprevioustrack:
