如何在 MPRemoteCommandCenter 中切换 Play/Pause

Question

我不知道如何切换播放和暂停按钮。我试过 TogglePlayPauseCommand。但它不起作用。

您能否 post 关于您如何尝试实现 TogglePlayPauseCommand 的代码？我想应该是这样的：

public override void ViewDidLoad()
{
    base.ViewDidLoad ();
    var commandCenter = MPRemoteCommandCenter.Shared;
    commandCenter.TogglePlayPauseCommand.AddTarget (ToggledPlayPauseButton);
}

public MPRemoteCommandHandlerStatus ToggledPlayPauseButton(MPRemoteCommandEvent commandEvent)
{
     Console.WriteLine ("Toggled");
    return MPRemoteCommandHandlerStatus.Success;
}
