I hvae addd one webview having youtube link. When user play viedo it defaults open iOS movie player. I want to track notification of that movie player when it exits full screen or playing stopped. I have tried all notification generated by MPMoviewPlayerController . None of them are being fired. It fiers only when we instatinate MPMoviewPlayerViewCotntroller object and present MPMoviewPlayer from that.
That's becuase Youtube videos inside UIWebView are not MPMoviewPlayerViewCotntroller.
On iOS7:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerWillEnterFullscreen:)
name:#"UIMoviePlayerControllerDidEnterFullscreenNotification"
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerWillExitFullscreen:)
name:#"UIMoviePlayerControllerWillExitFullscreenNotification" object:nil];
On iOS8 it's a bit of a problem because these events are gone, and you need to add observer like so:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(ios8EnterFullscreen:)
name:UIWindowDidBecomeVisibleNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(ios8ExitFullscreen:)
name:UIWindowDidBecomeHiddenNotification object:nil];
And check that when it fires it is indeed a movie player (because it fires also on UIAlertView and stuff):
- (void)ios8EnterFullscreen:(NSNotification *)notification
{
if ([notification.object isMemberOfClass:[UIWindow class]])
{
//do your thing...
}
}

I added a notification with the following code,
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(videoLoadingComplete)
name:MPMovieNaturalSizeAvailableNotification
object:self.streamPlayer];
but it did not enter in the videoLoadingComplete function even after the video stars playing.
You can use following code
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviestart:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
-(void)moviestart
{
//your code here
}
I have created a device orientation listener to catch when the device is rotated, like so
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(jumpBarButtonPosition)
name:#"UIDeviceOrientationDidChangeNotification" object:nil];
however inside the jumpBarButtonPosition method I have changed from using UIDeviceOrientation to statusBarOrientation, so I am woundering what I could replace UIDeviceOrientationDidChangeNotification with in order to only receive notifications about the statudBarOrientation changes.
Don't type it as a string:#"UIDeviceOrientationDidChangeNotification" use:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(jumpBarButtonPosition)
name:UIDeviceOrientationDidChangeNotification object:nil];
I am trying to call a method within an uiview from AppDelegate using the NSNotificationCenter to no avail..
AppDelegate.m
[[NSNotificationCenter defaultCenter] postNotificationName:#"ProcessDidComplete" object:items];
Then via MainStoryboard, the main view is loaded which controller class is MainViewController
in MainViewController.h viewDidLoad i have
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(ProcessDidComplete:) name:#"ProcessDidComplete" object:nil];
and then the method
- (void) ProcessDidComplete:(NSNotification *)pNotification
but it never gets called.
Thanks for any help!
just change a way..
First add observer
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(ProcessDidComplete:) name:#"ProcessDidComplete" object:nil];
Then Post Notification
[[NSNotificationCenter defaultCenter] postNotificationName:#"ProcessDidComplete" object:items];
Finally remove in viewWillDisappear
[[NSNotificationCenter defaultCenter] removeObserver:self name:#"ProcessDidComplete" object:nil];
Your code looks okay, which makes me wonder where in your app delegate you post the notification?
If you post the notification before you add the observer in the view controlller, then the notification will never be received. Can you not send the message to the main view controller directly, i.e., as a property, rather than using notifications?
Just wanted to note here that iOS notification names are case-sensitive:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(handUpdate:) name:#"scheduleUpdated" object:nil];
will not respond to:
[[NSNotificationCenter defaultCenter] postNotificationName:#"ScheduleUpdated" object:items];
(as I spent the last 20 minutes figuring out...)
I have used MPMoviePlayerController for playing video file.I want to get done button event but i dont know how to get can you help me for this questions
You can use MPMoviePlayerPlaybackDidFinishNotification.. Dont think there is a notification that only triggers when the done button is pressed and not when the movie finishes by itself thou...
Add this when creating the MPmovieplayerController:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayBackDidFinish: ) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer] ;
And then this method:
-(void)moviePlayBackDidFinish: (NSNotification*)notification{
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer] ;
[moviePlayer stop];
[moviePlayer release];
}
I'm having lots of trouble displaying a fullscreen movie in my iPad app and then allowing the user to dismiss it with either the Done button or the "un-fullscreen" button on the player controls.
Initially I was using MPMoviePlayerViewController for the movie presentation, but I wasn't receiving the enter/exit fullscreen notifications from its MPMoviePlayerController object, so I switched to doing it myself.
I can make the movie appear fullscreen (although the transition is janky), but when either the "Done" or "un-fullscreen" buttons are pressed, no action is taken by the player. I've posted my code below:
- (void)startPlayingMovieWithURLString:(NSString *)movieURLString {
// I get all of these callbacks **EXCEPT** the "willExitFullScreen:" callback.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willEnterFullScreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willExitFullScreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(didFinishPlayback:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self.moviePlayerController setContentURL:someExistingURL];
// "self" is a UIViewController subclass, and is presented as a "fullscreen" modal view controller from its parent
// I'm setting the movie player's view's frame to take up the full rectangle of my view controller, but really I want the movie to be completely removed when the user presses "done" (that is, removed from the view hierarchy). Not sure when/where to do this.
self.moviePlayerController.view.frame = self.view.frame;
[self.view addSubview:self.moviePlayerController.view];
[self.moviePlayerController setFullscreen:YES animated:YES];
}
And here is the code for my didFinish callback
- (void)didFinishPlayback:(NSNotification *)notification {
// This ends up recursively telling the player that playback ended, thus calling this method, thus…well you get the picture.
// What I'm trying to do here is just make the player go away and show my old UI again.
[self.moviePlayerController setFullscreen:NO animated:YES];
}
So obviously I am doing something wrong but I've been up and down the documentation and I can't figure out how to make the movie just go away. I figured it would be more intuitive than this. What am I doing wrong?
Here are how the events -> notifications work:
User presses 'Done' button
MPMoviePlayerWillExitFullscreenNotification
MPMoviePlayerDidExitFullscreenNotification
User presses 'Leave fullscreen' button on transport
MPMoviePlayerWillExitFullscreenNotification
MPMoviePlayerDidExitFullscreenNotification
Note that playback does not stop
Movie reaches end
MPMoviePlayerPlaybackDidFinishNotification with the MPMoviePlayerPlaybackDidFinishReasonUserInfoKey set to MPMovieFinishReasonPlaybackEnded
If you call setFullscreen:NO animated:YES on your MoviePlayerController instance from this notification, you'll then get the WillExit and DidExit notifications.
Note that you don't get the PlaybackDidFinish notification when the user presses the Done or Leave Fullscreen buttons.
So, typically, if you want to get rid of the MoviePlayer's view, you need to put [self.moviePlayerController.view removeFromSuperview] in the DidExitFullscreen notification handler. WillExitFullscreen is too soon.
Here's my code:
- (void)willEnterFullscreen:(NSNotification*)notification {
NSLog(#"willEnterFullscreen");
}
- (void)enteredFullscreen:(NSNotification*)notification {
NSLog(#"enteredFullscreen");
}
- (void)willExitFullscreen:(NSNotification*)notification {
NSLog(#"willExitFullscreen");
}
- (void)exitedFullscreen:(NSNotification*)notification {
NSLog(#"exitedFullscreen");
[self.movieController.view removeFromSuperview];
self.movieController = nil;
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)playbackFinished:(NSNotification*)notification {
NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
switch ([reason intValue]) {
case MPMovieFinishReasonPlaybackEnded:
NSLog(#"playbackFinished. Reason: Playback Ended");
break;
case MPMovieFinishReasonPlaybackError:
NSLog(#"playbackFinished. Reason: Playback Error");
break;
case MPMovieFinishReasonUserExited:
NSLog(#"playbackFinished. Reason: User Exited");
break;
default:
break;
}
[self.movieController setFullscreen:NO animated:YES];
}
- (void)showMovie {
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willExitFullscreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(enteredFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(exitedFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
NSURL* movieURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"tron" ofType:#"mov"]];
self.movieController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
self.movieController.view.frame = self.view.frame;
[self.view addSubview:movieController.view];
[self.movieController setFullscreen:YES animated:YES];
[self.movieController play];
}
Yes. That's great. There are really notifications mentioned above...
However, there are no MPMoviePlayerPlaybackWillFinishNotification somewhy!!!
That's really a problem.
When you call the movie player as modal (no matter which of the following methods used presentViewController/presentModalViewController/presentVideoController), if you defined .fullScreen = YES, it's not expected to call MPMoviePlayerWillExitFullscreenNotification notification at all (obviously, because it's not cosidering we enter/exit from full screen, but only present/dismiss the controller).
But there are really no any notifications that the video is about to finish and close. That's needed (besides any other situations possible) to catch the moment when the transition of dismissing is started. (The transition, of course, starts before the MPMoviePlayerPlaybackDidFinishNotification called). And, at the same time, application:supportedInterfaceOrientationsForWindow: for previously shown controller is called before the notification, and there is no way to say the AppDelegate that our current controller must be shown already in another orientation.
So, since my video is fullscreen and also without any controls shown (this is kind of an intro, so I just until it finishes) my solution was just to have a timer which checks every short tick (0.1 seconds) what is the video current position... and it it's close to the end, then this is the moment for my own notification.
