ヘッドフォン ボタンなどのリモート コントロール イベントを受信するための実際の例を示す、モノタッチの実際のサンプルがあるかどうかを知りたいです。
私は単一のビューのiPhoneアプリを実装し、CanBecomeFirstResponderを実装し、BecomeFirstResponderとUIApplication.SharedApplication.BeginRecomingRemoteControlEvents()を呼び出しましたが、イベントを取得しません。
これが私のSingleViewControllerのコードです。
public partial class SingleViewViewController : UIViewController
{
public SingleViewViewController () : base ("SingleViewViewController", null)
{
}
public override void DidReceiveMemoryWarning ()
{
// Releases the view if it doesn't have a superview.
base.DidReceiveMemoryWarning ();
// Release any cached data, images, etc that aren't in use.
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
// Perform any additional setup after loading the view, typically from a nib.
AVAudioSession audioSession = AVAudioSession.SharedInstance();
NSError error;
audioSession.SetCategory(AVAudioSession.CategoryPlayback, out error);
audioSession.SetActive(true,out error);
this.BecomeFirstResponder();
UIApplication.SharedApplication.BeginReceivingRemoteControlEvents();
}
public override void ViewDidUnload ()
{
base.ViewDidUnload ();
// Clear any references to subviews of the main view in order to
// allow the Garbage Collector to collect them sooner.
//
// e.g. myOutlet.Dispose (); myOutlet = null;
ReleaseDesignerOutlets ();
}
public override bool ShouldAutorotateToInterfaceOrientation (UIInterfaceOrientation toInterfaceOrientation)
{
// Return true for supported orientations
return (toInterfaceOrientation != UIInterfaceOrientation.PortraitUpsideDown);
}
public override bool CanBecomeFirstResponder {
get {
return true;
}
}
public override bool CanResignFirstResponder {
get {
return false;
}
}
public override void RemoteControlReceived (UIEvent theEvent)
{
base.RemoteControlReceived (theEvent);
}
}
