Answer 1

As of iOS 6, there is an alternative method that's more compact than Ramin's answer.

#import 

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback
                                       error:nil];

To allow background audio from other apps to continue playing, add the AVAudioSessionCategoryOptionMixWithOthers option:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback
                                 withOptions:AVAudioSessionCategoryOptionMixWithOthers
                                       error:nil];

There's further details in Apple's AVAudioSession Class Reference.
