Just an FYI that you can now play .mp3 files (and other file types) using the MPMoviePlayerController. I used the code below in my application:
MPMoviePlayerController *playerViewController;
NSURL *movieURL = [NSURL URLWithString:myMovieStringName];
playerViewController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
playerViewController.controlStyle = MPMovieControlStyleFullscreen;
playerViewController.shouldAutoplay = YES;

[[playerViewController view] setFrame: CGRectMake(0.0, 0.0, 350.0, 250.0)]; // 2X the native resolution
[self.playerView addSubview: [playerViewController view]];

Hi,

I use the same technics as you explain but sometimes, when after clicking on the “done” button, view dismiss and automaticaly restart after 1 second.

Does anyone get the same problem?

Alternatively you can:

MPMoviePlayerController *mediaPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:contentURL]];
[mediaPlayer play];

With this you can register an action with the MPMoviePlayerPlaybackDidFinishNotification by doing:

// Register to receive a notification when the movie has finished playing.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(mediaPlayerPlaybackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mediaPlayer];

Kind of digging up old discussion here but I found a solution to the “playing twice” issue. Just keep a reference to the web view around. Each time you need to play a new MP3, deallocate it (remove it from the superview, release, etc.) and then create a new one. This ensures the web view is new and doesn’t play the previously played MP3 for some reason.

I tried a bunch of stuff using UIWebViewDelegate and you just can’t jack into the order of events in any way to prevent previous playing, so this seems to be the only way. If you do it right you won’t have any memory leaks – run Instruments just to double check your logic.

@stinki: The UIWebView cannot load and parse and XML for your MP3 URLs. You could load and parse the XML in your own code and then send the URLs to the UIWebView.

It is working with a .pls also, only I have one bug I can’t seem to figure out. The playlist keeps reloading until I quit the app. Here’s my viewDidUnload code, anybody see something I’m forgetting?

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
[self.myWebView stopLoading];
self.myWebView.delegate = nil;
[self.navigationController popViewControllerAnimated:YES];

This was exactly what I was looking for….I was about to embark on coding the streaming, having not even thought about just letting Safari handle it. Much easier. Thanks.
