当然你的程序不一定是播放器应用，但是我们仍然可以让它具有这个功能，让用户通过耳机进行一些比较简单常用的操作，这样是不是很酷呢？
具体的怎么实现呢？废话不多说，我们直奔主题：
1，允许接受Remote事件
[self becomeFirstResponder];
- (void) remoteControlReceivedWithEvent: (UIEvent *) receivedEvent {
if (receivedEvent.type == UIEventTypeRemoteControl)
{
switch (receivedEvent.subtype) {
case UIEventSubtypeRemoteControlTogglePlayPause:
//do something
break;
case UIEventSubtypeRemoteControlPreviousTrack:
//do something
break;
case UIEventSubtypeRemoteControlNextTrack:
//do something
break;
default:
break;
}
}
}
[[UIApplication sharedApplication] endReceivingRemoteControlEvents];
[self resignFirstResponder];
UIEventSubtypeMotionShake = 1,
UIEventSubtypeRemoteControlPlay = 100,
UIEventSubtypeRemoteControlStop = 102,
UIEventSubtypeRemoteControlNextTrack = 104,
UIEventSubtypeRemoteControlBeginSeekingBackward = 106,
UIEventSubtypeRemoteControlBeginSeekingForward = 108,
} UIEventSubtype;

最近发现也有人在坛子里发帖求获取ios耳机线控事件，下面给大家分享一下代码，
-(BOOL)canBecomeFirstResponder{
NSLog(@"_____%s_____",__FUNCTION__);
return YES;
}
//received remote event
-(void)remoteControlReceivedWithEvent:(UIEvent *)event{
NSLog(@"event tyipe:::%d subtype:::%d",event.type,event.subtype);
//type==2 subtype==单击暂停键：103，双击暂停键104
if (event.type == UIEventTypeRemoteControl) {
switch (event.subtype) {
case UIEventSubtypeRemoteControlPlay:{
NSLog(@"play---------");
}break;
case UIEventSubtypeRemoteControlPause:{
NSLog(@"Pause---------");
}break;
case UIEventSubtypeRemoteControlStop:{
NSLog(@"Stop---------");
}break;
case UIEventSubtypeRemoteControlTogglePlayPause:{
//单击暂停键：103
NSLog(@"单击暂停键：103");
}break;
case UIEventSubtypeRemoteControlNextTrack:{
//双击暂停键：104
NSLog(@"双击暂停键：104");
}break;
case UIEventSubtypeRemoteControlPreviousTrack:{
NSLog(@"三击暂停键：105");
}break;
case UIEventSubtypeRemoteControlBeginSeekingForward:{
NSLog(@"单击，再按下不放：108");
}break;
case UIEventSubtypeRemoteControlEndSeekingForward:{
NSLog(@"单击，再按下不放，松开时：109");
}break;
default:
break;
}
}
}
把上面代码加进去就能获取耳机线控的各个点击事件，嘀嘀打车之前版本中有一个耳机抢单的功能，就是这么实现的
