Question

My problem; Hide the default camera controls and overlay it with my my own. This is made with the property cameraOverlayView. I also was having problem triggering the takePicture method.

The OP wrote:

Here is what came to be the solution:

I have two UIViewController. The main ViewController and the CustomOverlay (for the camera controls).

I the ViewController I declare the source type and the overlay for may camera control like this:

- (void)viewDidLoad
{
    // notification from the CustomOverlay Controller that triggers the eTakePicture method
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(eTakePicture:) name:@"eTakePicture" object:nil];

    daysBtn.delegate = self;
    daysBtn.hidden = YES;

    picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
    picker.showsCameraControls = NO;
    picker.navigationBarHidden = YES;
    picker.wantsFullScreenLayout = YES;
    picker.delegate = self;

    overlay = [[CustomOverlay alloc] initWithNibName:@"CustomOverlay" bundle:nil];
    // Overlay for the camera controls, note the "= overlay.view", the ".view" was important
    // because the overlay is a new UIViewcontroller (with xib) so you have to call the
    // view. Most tutorials that I saw were based on UIView so only "= overlay" worked.
    picker.cameraOverlayView = overlay.view;
    [self presentModalViewController:picker animated:NO];

    [super viewDidLoad];
}

Now on the CustomOverlay, which is a UIViewController I have the take picture button and want this button to trigger a method in the main ViewController:

- (IBAction)shoot:(id)control {

    [[NSNotificationCenter defaultCenter] postNotificationName:@"eTakePicture" object:self];

}

And back to the main ViewController:

-(void)eTakePicture:(NSNotification *)notification
{
    [picker takePicture];
}

All the code above will change a little more once I review it, specially the first block where I have to have a condition to check if cameraSourceType is available.

Hope that helps somebody out there. Any question, just ask.
