How to play m3u audio stream in iOS app - ios

Question

I'm trying to create an iOS/iPhone radio app using Xcode 4.5.2.
I wanted to stream #"http://xx.xxxxxxx.com/8111/radio.m3u" with play, pause, volume control and able to play on background feature/multitasking.
I've added AVFoundation, Mediaplayer and AudioToolBox frameworks thus far. I've added play, pause and slider objects to xib.
ViewController.h
#interface ViewController : UIViewController
#property (strong,nonatomic) MPMoviePlayerController *myPlayer;
#property (weak, nonatomic) IBOutlet UISlider *myslider;
- (IBAction)playButtonPressed;
- (IBAction)myslider:(id)sender;
#end
ViewController.m
#import "ViewController.h"
#import <MediaPlayer/MediaPlayer.h>
#interface ViewController ()
{
UISlider *volumeSlider;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
UIBackgroundTaskIdentifier newTaskId = UIBackgroundTaskInvalid;
newTaskId = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:NULL];
}
- (IBAction)playButtonPressed;
{
NSString *urlAddress = #"http://xxxxxxx.com/8111/listen.m3u";
NSURL *url = [NSURL URLWithString:urlAddress];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;
[player prepareToPlay];
self.myPlayer = player;
[self.view addSubview:self.myPlayer.view];
[self.myPlayer play];
}
- (IBAction)stopButtonPressed;
{
[self.myPlayer stop];
}
- (IBAction)myslider:(id)sender
{
MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame: CGRectMake(10, 10, 200, 40)];
[volumeSlider addSubview:volumeView];
[volumeView sizeToFit];
}

Answer 1

There are Two way to achieve this.
You can directly load you URL in UIWebView and it will properly.
You can also use MPMoviePlayerController.

Answer 2

Create a "MPMoviePlayerController *player" as a strong object in your ViewController.
So you code would look something like below:
#interface ViewController ()
{
UISlider *volumeSlider;
MPMoviePlayerController *player;
}
#end
- (IBAction)playButtonPressed;
{
NSString *urlAddress = #"http://xxxxxxx.com/8111/listen.m3u";
NSURL *url = [NSURL URLWithString:urlAddress];
if(nil != player)
{
player = nil; // Alternatively you can stop and restart with the different stream.
}
player = [[MPMoviePlayerController alloc]initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;
[player prepareToPlay];
self.myPlayer = player;
[self.view addSubview:self.myPlayer.view];
[self.myPlayer play];
}
