MPMoviePlayerController worked fine up to iOS 4.0 now just plays sound, no video
The code below is more or less taken from the example MPMoviePlayerController sample code. In an app I wrote last year, it used to play videos ful开发者_StackOverflowlscreen without an issue. Since iOS 4.0, there's just audio in the background. It's like the movie player doesn't have a view or the view is behind my app. I can still interact with my app, even 'start' a new video (audio only).
It's like the movie player now needs a view, but I don't see any way of supplying this in the API or the sample code (which does seem to be a version or two behind.
I load my videos from a URL and if I type these into Safari, they play just fine.
Here's the relevant code fragments, for what it's worth:
- (void)playMovieUrl:(NSURL*)url
delegate:(id)delegate
callbackSelector:(SEL)selector
{
@try {
movieFinishedCallbackDelegate = delegate;
movieFinishedCallbackSelector = selector;
movieURL = url;
MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(myMovieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[theMovie play];
}
@catch (NSException * e) {
return;
}
}
// When the movie is done,release the controller.
-(void)myMovieFinishedCallback:(NSNotification*)aNotification
{
MPMoviePlayerController* theMovie=[aNotification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:theMovie];
[theMovie release];
[movieURL release];
[movieFinishedCallbackDelegate performSelector:movieFinishedCallbackSelector];
}
You probably need to present theMovie:
[self presentMoviePlayerViewControllerAnimated:theMovie];
And change to:
MPMoviePlayerViewController
in ios 3.2 letter use MPMoviePlayerViewController. it behave like a modelViewcontroller
