Rotating a video with iPhone Simulator

I used this youtube video (http://www.youtube.com/watch?v=j6922mZ0WUU) to make an application where an iPhone shows a video.
However, starting at 4:25, I used another code (the code of the video does not work with the current sdk).

Here's the code that i used:

- (IBAction)playMovie {
	NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"MOVIE001" ofType:@"mov"]];  
	MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];  
	// Register to receive a notification when the movie has finished playing.  
	[[NSNotificationCenter defaultCenter] addObserver:self  
	if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {  
		// Use the new 3.2 style API  
		moviePlayer.controlStyle = MPMovieControlStyleNone;  
		moviePlayer.shouldAutoplay = YES;  
		[self.view addSubview:moviePlayer.view];  
		[moviePlayer setFullscreen:YES animated:YES];  
	} else {  
		// Use the old 2.0 style API  
		moviePlayer.movieControlMode = MPMovieControlModeHidden;  
		[moviePlayer play];  


Open in new window

The application is running ok but when I turn the iPhone simulator the video doesn't rotate.

What changes should I do in my code?

Thanks and sorry for my bad english!

Just found a nice article:
Play iPhone Movies in Portrait Mode with MPMoviePlayerController using Public API’s
You can download the source code - in the bottom of the article. It looks very nice.

The answer on your question is here:

You will see - people proposes to make new class derived from the movie controller and add method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);

Then use this class instead of the  MPMoviePlayerController.

BTW, please pay attention on movieFinishedCallback - that's answer on your question how to know when the show finished (if you are still looking for it).

could you explain better how can i "make new class derived from the movie controller and add method"?
how can i use this class instead of the MPMoviePlayerController?
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

i try to open.

i put:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
inside the ibaction playmovie.
the video now is widescreen, but when i rotate the iphone simulator the video dont rotate.

and at .h, when i try to put
@interface MyMovieViewController : MPMoviePlayerViewController

i got an error cannot find interface declaration for 'MPMoviePlayerController', superclass of 'MyMovieViewController'

MPMoviePlayerViewController - that's the point. It's a night here already. Maybe because of that, I missed that before.
Here you will find full program: http://www.devx.com/wireless/Article/44642/1954
It has movieFinishedCallback (you asked in your first question about the subject).
It shows how to switch to the portrait mode:
[player setOrientation:UIDeviceOrientationPortrait animated:NO];

This app, when you will have it working, will be a base for other improvements.
Sorry, I just started from the code you proposed - MoviePlayer sample.

all right but i follow the steps of this link http://www.devx.com/wireless/Article/44642/1954
but when i debug it, i can hear the sound but i cant see the video images.
i believe that is a sdk problem, because he made it with a older version than the mine.

Because this part changed in iOS 4. Compare with other examples you have and see them working.
