text
Body
copied!<p>Help me on this issue please. I am new to Xcode, so please explain to me in detail.</p> <p>In my app there is audio and video included, but I have only included the audio coding.</p> <p>Audio file is 30 min. long. Audio pauses when device switches off, NOT PLAYING IN BACKGROUND basically.</p> <p>I have tested this on my iPhone 4S. It starts playing for about 1 min., then phone goes to sleep as normally it does. Suddenly audio stopped playing. When you switch ON the phone, it starts playing again where it was stopped.</p> <p>I want the audio to play continuously even the phone goes to sleep.
