IOS 5 No audio when playing a video with Silent mode on with a buzztouch app

Question

I have done several apps with buzztouch for Iphone and Ipads, here is a free one as an example :

Answer 1

What you are describing is the default behavior in iOS - when the ring/silent switch is in silent mode all audio from your app will be suppressed.

I don't know about implementing this from BuzzTouch, but here is a native solution I used to get around this for one of my apps that plays video:

MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:myVidURL];

... set up player ...

// prevent mute switch from switching off audio from movie player
NSError *_error = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &_error];

[self presentMoviePlayerViewControllerAnimated:mpvc];

You will also need to include the AVFoundation framework for this to work.
