耳机线控

mac2022-06-30  21

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
