Designing a generative music system for iOS, using OpenFrameworks, I'd need to provide a mode in which the user could listen the music produced by the application when:
Some applications like BLOOM, or alarm clock, works like that and propose to users a switch to enable/disable this feature.
Any tips for that ?
You need to make couple of changes in plist file.
i.e. 1) Set Required background mode to App plays audio
2) set Application does not run in background to NO.
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
Then, you need to write these much code in AppDelegate
Now, you can easily run audio while phone screen locks or goes in background.
