I am creating a radio streaming app with play, pause and volume slider.
I have implemented volume slider using MPVolumeView but unfortunately it is not working.
Can any one please let me know the correct code so that the volume slider will work in my app. I have used MPMoviePlayerController, AVPlayer, AVAudioPlayer.
Sounds as if you missed an important part of Apple's documentation;
Working with Movies and iPod Music
I am suspecting that you are using both, AVAudioPlayer and MPMoviePlayerController together and that you have setup some audio session attributes to get that working properly. Now when doing so, you may want to tell MPMoviePlayerController to use that session / or not.
Using the Media Player Framework Exclusively
If your application is using a movie player only, or a music player
only—and you are not playing your own sounds—then you should not
configure an audio session.
If you are using a movie player exclusively, you must tell it to use
its own audio session, as follows:
myMoviePlayer.useApplicationAudioSession = NO
If you are using a movie
player and a music player, then you probably want to configure how the
two interact; for this, you must configure an audio session, even
though you are not playing application audio per se. Use the guidance
in Table 6-1.

I am developing application like gaana.com
Which player can be used for play mp3 songs from server url ? I want
to implement Play, Pause, Next, Previous buttons And will also play
song list in background mode one by one.
I have already implemented AVPlayer but i getting issue in playing
next audio in background mode. And i had tried all answers regarding
this issue but none of all is working for me.
So i am finding alternative of AVPlayer.
Using the AVAudioSession class, it is possible to play audio in the background, but I was wondering if it is possible to play audio in the background and having the built-in music player playing at the same time. Based on the documentation, this seems to be impossible.
Is there a configuration that I am overlooking or a reliable workaround?
I'm writing a music player for iOS that needs to have all the features of the built-in Music app. My app needs to continue running in the background so I have to use the AVPlayer class.
Are there any open source implementations out there that I can use instead of writing the whole thing myself?
Just found this. It works great:

If you want to play tracks from your iTunes music library, and don't want to use the MPMusicPlayerController class, your best bet is to use AVPlayer or AVQueuePlayer (subclass of AVPlayer). You must establish the appropriate audio session and register to receive remote control events for the app to continue playing music in the background.
There are downsides to this method; you won't be able to play DRM-protected tracks and audiobooks purchased from the iTunes store. There's no way to instantiate an iTunes Match download with the AVPlayer class. Furthermore, you'll have a bit of work on your hands if you want to add gapless playback and equaliser settings (The closest you'll get to gapless playback is with the AVQueuePlayer subclass, though in theory, you could overlap AVPlayers with an NSTimer).
You'll also need to change 'Required Background Modes' in your Info.plist to 'App plays audio'
As for the rest of your app, I suggest you read up on UITabBarControllers and UITableViewControllers along with MPMediaQuerys.
See this solution for the audio part.
The application I'm currently working on plays background sound by using AVFoundation and effect sounds using the Finch engine. Problem is when I try to record video with sound (i.e. add a audio input to the session) by using AVFoundation lower level classes all sounds suddenly stop. Also, on iOS 5, if I try to record a second video I get an error. If the video is recorded without audio everything is fine. Any ideas what the cause might be
Your audio session is being interrupted by the AVFoundation daemon. You need to set a non-exclusive audio session category to stop this happening.
See the Audio Session Cookbook section of the Audio Session Programming Guide.
Within my application, I am playing downloaded audio using an AVAudioPlayer, while simultaneously playing audio from the user's iPod music library with an MPMusicPlayerController.
I need to be able to adjust the Volume of the AVAudioPlayer instance so that it's louder
than the audio coming from the MPMusicPlayerController.
The problem is, when I adjust the Volume property of the AVAudioPlayer, it also
adjusts the volume of the MPMusicPlayerController.
Is there any solution which would allow me to independently control the volume of
these two players?
If not, is there another technique I should use to do this? Any help is appreciated.
Take a look at the documentation for AVAudioSession. For example, in the AVAudioSession Programming Guide, says the following:
"Finally, you can enhance a category to automatically lower the volume of other audio when your audio is playing. This could be used, for example, in an exercise application. Say the user is exercising along to their iPod when your application wants to overlay a verbal message—for instance, “You’ve been rowing for 10 minutes.” To ensure that the message from your application is intelligible, apply the kAudioSessionProperty_OtherMixableAudioShouldDuck property to your audio session. When ducking takes place, all other audio on the device—apart from phone audio—lowers in volume."
I think it might solve your problem. The documentation on initializing an AVAudioSession and setting its categories and properties is pretty clear and easy to follow; you should have no trouble.
