iphone - 验证 iphone 是否已连接到基座

Question

当我将 iPhone 连接到扩展坞时，我的应用程序会显示消息:“连接器扩展坞”。我想检测手机何时与其他设备连接并隐藏 MPVolumeView 以避免这些消息。

我像往常一样使用 MPVolumeView:

MPVolumeView *myVolume = [[MPVolumeView alloc] initWithFrame:CGRectMake(10, 435, 300, 0)];
[myVolume sizeToFit];
[self.view addSubview:myVolume];
[myVolume release];

谁能帮帮我？

我通过添加以下观察者来做到这一点:

NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];
EAAccessoryManager *accessoryMamaner  = [EAAccessoryManager sharedAccessoryManager];

[accessoryMamaner registerForLocalNotifications];
[notificationCenter addObserver: self  selector: @selector (accessoryDidConnect:)   name: EAAccessoryDidConnectNotification object: nil];
[notificationCenter addObserver: self  selector: @selector (accessoryDidDisconnect:)   name: EAAccessoryDidDisconnectNotification object: nil];
