I would like to test around a bit with augmented reality. My first problem is how to get the picture that comes from the camera as background for my view? For what i want to do, i dont need to access the picture, i just need it as background. I found a few solutions how to take a picture with the camera, but nothing that gives me a picture that comes from the camera.
thanks,.
I would use AVFoundation for that.
You need to set up an AVCaptureSession with an AVCaptureDevice and an AVCaptureDeviceInput. Finally – and this is what you’re interested in – set up an AVCaptureVideoPreviewLayer.
Send the startRunning: message to your AVCaptureSession object, and you should be good to go.
