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];
2,处理输入事件:
- (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;
}
}
}
3,在使用完毕的时候停止接受Remote事件[[UIApplication sharedApplication] endReceivingRemoteControlEvents]; [self resignFirstResponder];
4,附上完整的事件类型代码,供大家使用typedef enum {
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
