I was wondering if there was a specific method called when we press the 2 buttons of the iPhone (using Home-Button & Power on/off) to take a screenshot. If yes, I would known his name to use her in programming.

It is a system level service for which the app never receives any notification or method call.

I believe that would be a native method, not accessible from the IPhone SDK. In what context are you going to be using this? You might be looking for this - Take screenshot from code

There used to be a UIGetScreenImage() function that you could use to capture the screen. Apple no longer allows use of that function in App Store apps, so you have a few other options. CALayer has a -renderInContext: method—Google it—that you can use to copy a view’s contents to a graphics context; this does not, however, work for OpenGL content, video, or live imagery from a device’s camera. I’m not sure about solutions for the first two, but for the latter—getting images from the camera—you’ll need to use the AVFoundation framework.

Yeah, it is. If you want to capture still images or video from the camera, you use AVFoundation. – Noah Witherspoon May 12 '11 at 17:11

I want to take a screenshot when the camera is running, I think AVFoundation is like the method takePicture(). – Volg May 13 '11 at 07:31
