ios程式支援耳機線控

1，允許接受Remote事件

[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];

這句很重要，不然有些裝置不響應

- (BOOL) canBecomeFirstResponder {

    return YES;

}

2，處理輸入事件：

- (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,在使用完畢的時候停止接受Remote事件

[[UIApplication sharedApplication] endReceivingRemoteControlEvents];
[self resignFirstResponder];

4，附上完整的事件類型代碼,供大家使用

typedef enum {

UIEventSubtypeNone = 0,

 UIEventSubtypeMotionShake = 1,

 UIEventSubtypeRemoteControlPlay = 100,

UIEventSubtypeRemoteControlPause = 101,

UIEventSubtypeRemoteControlStop = 102,

UIEventSubtypeRemoteControlTogglePlayPause = 103,

UIEventSubtypeRemoteControlNextTrack = 104,

UIEventSubtypeRemoteControlPreviousTrack = 105,

UIEventSubtypeRemoteControlBeginSeekingBackward = 106,

UIEventSubtypeRemoteControlEndSeekingBackward = 107,

UIEventSubtypeRemoteControlBeginSeekingForward = 108,

UIEventSubtypeRemoteControlEndSeekingForward = 109,

} UIEventSubtype;

好了，關於耳機模式的使用就說到這裡了。
