问题
When I open a UIImagePickerController, I can display the device's camera input stream.
But when I play an AVAudioPlayer with [player play] then the camera stops working.
How can I deal with that?
回答1:
you can't because UIIMagePickerController is controlling the audio, you will need to use low level AVFoundation in order to do that.
checkout AVCam sample code how to record a movie and add the view as subview , that way you will stay in control of the audio and will be able to play audio.
