iOS taking photo programmatically

by

This is very simple, just use the AVFoundation reference guide:

https://developer.apple.com/library/ios/#documentation/AudioVideo/Conceptual/AVFoundationPG/Articles/04_MediaCapture.html

If you don’t want the user to see the preview input you can just skip the set preview layer part of the code.

Edit: To be more detailed.

1)You set your capture configuration using the AVFoundation.

  • Set the camera input to frontal, turn off flash etc etc.

2)You SKIP the part where the video preview layer is set.

3)You call the captureStillImageAsynchronouslyFromConnection:completionHandler: method whenever you want the picture to be taken.

Note: If you want the flash to not be heard and such then you might be violating the user rights in some countries (japan for example). One workaround I know of to do so is by capturing a frame of a video (does not trigger flash).
