There are a lot of questions about this problem on SO:
- AVFoundation, how to turn off the shutter sound when captureStillImageAsynchronouslyFromConnection?
- How can I mute the capture sound in AVFoundation?
- I wish i could mute shutter sound of camera using ios sdk
But really no one answer works for me.
How do I capture an image programmatically without the camera shutter sound activating?
