Setting a background image/view to live camera view?

Question

Is it possible to set a background for a particular view controller to show a live camera view? If so, could one lead me in the right direction to make this possible?

Answer 1

Import:

#import 

To add camera view to a controller's view add this code in the viewDidLoad:

AVCaptureSession *session = [[AVCaptureSession alloc] init];
session.sessionPreset = AVCaptureSessionPresetHigh;

AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

NSError *error = nil;
AVCaptureDeviceInput *input = [AVCaptureDeviceInput deviceInputWithDevice:device error:&error];
[session addInput:input];

AVCaptureVideoPreviewLayer *newCaptureVideoPreviewLayer = [[AVCaptureVideoPreviewLayer alloc] initWithSession:session];
newCaptureVideoPreviewLayer.frame = self.view.bounds;

[self.view.layer addSublayer:newCaptureVideoPreviewLayer];

[session startRunning];
