// listening
notification = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically ((sender, args) => {
/* Access strongly typed args */
Console.WriteLine ("Notification: {0}", args.Notification);
Console.WriteLine ("_AudioRendererFlushTime", args._AudioRendererFlushTime);
});
// To stop listening:
notification.Dispose ();
//
//Method style
//
NSObject notification;
void Callback (object sender, AVFoundation.AudioRendererWasFlushedAutomaticallyEventArgs args)
{
// Access strongly typed args
Console.WriteLine ("Notification: {0}", args.Notification);
Console.WriteLine ("_AudioRendererFlushTime", args._AudioRendererFlushTime);
}
void Setup ()
{
notification = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically (Callback);
}
void Teardown ()
{
notification.Dispose ();
}
適用於
ObserveAudioRendererWasFlushedAutomatically(NSObject, EventHandler<AudioRendererWasFlushedAutomaticallyEventArgs>)
public static Foundation.NSObject ObserveAudioRendererWasFlushedAutomatically (Foundation.NSObject objectToObserve, EventHandler<AVFoundation.AudioRendererWasFlushedAutomaticallyEventArgs> handler);

參數
- objectToObserve
- NSObject
傳回
權杖物件,可用來停止接收通知,方法是處置通知或傳遞至 RemoveObservers(IEnumerable<NSObject>)
備註
這個方法可用來訂閱 AudioRendererWasFlushedAutomaticallyNotification 通知。
// Listen to all notifications posted for any object
var token = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically ((notification) => {
Console.WriteLine ("Observed AudioRendererWasFlushedAutomaticallyNotification!");
};
// Listen to all notifications posted for a single object
var token = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically (objectToObserve, (notification) => {
Console.WriteLine ($"Observed AudioRendererWasFlushedAutomaticallyNotification for {nameof (objectToObserve)}!");
};
// Stop listening for notifications
token.Dispose ();
