如何在iOS应用中发挥的m3u音频流 [英] How to play m3u audio stream in iOS app

问题描述

我试图用X code 4.5.2创建的iOS / iPhone应用程序的无线电

我想流@http://xx.xxxxxxx.com/8111/radio.m3u有播放，暂停，音量控制，并能够在后台功能/多任务播放。

我已经添加了 AVFoundation ，媒体播放器和 AudioToolBox 框架迄今。我已经添加了播放，暂停和滑块对象厦门国际银行。

  ViewController.h@interface的ViewController：UIViewController中@property（强，非原子）的MPMoviePlayerController * myPlayer;@property（弱，非原子）IBOutlet中UISlider * myslider; - （IBAction为）为playButton pressed; - （IBAction为）myslider：（ID）发送;@结束ViewController.m
＃进口ViewController.h
＃进口＆LT;的MediaPlayer / MediaPlayer.h＆GT;@interface的ViewController（）
{
    UISlider * volumeSlider;
}@结束@implementation的ViewController - （无效）viewDidLoad中
{
    [超级viewDidLoad中];
    [UIApplication的sharedApplication] beginReceivingRemoteControlEvents]
    UIBackgroundTaskIdentifier newTaskId = UIBackgroundTaskInvalid;
    newTaskId = [[UIApplication的sharedApplication] beginBackgroundTaskWithExpirationHandler：NULL];
} - （IBAction为）为playButton pressed;
{
    * NSString的urlAddress = @http://xxxxxxx.com/8111/listen.m3u
    NSURL * URL = [NSURL URLWithString：urlAddress];
    *的MPMoviePlayerController播放器= [[的MPMoviePlayerController页头] initWithContentURL：URL];
    player.movi​​eSourceType = MPMovieSourceTypeStreaming;
    [播放器prepareToPlay]。
    self.myPlayer =玩家;
    [self.view addSubview：self.myPlayer.view];
    [self.myPlayer播放];
} - （IBAction为）STOPBUTTON pressed;
{
    [self.myPlayer站]
}
 - （IBAction为）myslider：（ID）发送者
{
    MPVolumeView * volumeView = [[MPVolumeView的alloc] initWithFrame：方法CGRectMake（10，10，200，40）];
    [volumeSlider addSubview：volumeView];
    [volumeView sizeToFit]
    }
 

解决方案

创建的MPMoviePlayerController *玩家作为您的ViewController一个强大的对象。

所以你code将类似于如下：

  @interface ViewController中（）
{
    UISlider * volumeSlider;
    *的MPMoviePlayerController播放器;
}@结束
 - （IBAction为）为playButton pressed;
{
    * NSString的urlAddress = @http://xxxxxxx.com/8111/listen.m3u
    NSURL * URL = [NSURL URLWithString：urlAddress];    如果（零！=玩家）
    {
      玩家=零; //或者你可以停止，并与不同的流重新启动。
    }    玩家= [[的MPMoviePlayerController页头] initWithContentURL：URL];
    player.movi​​eSourceType = MPMovieSourceTypeStreaming;
    [播放器prepareToPlay]。
    self.myPlayer =玩家;
    [self.view addSubview：self.myPlayer.view];
    [self.myPlayer播放];
}
 

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];
    }

解决方案

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];
}
