Integrating Camera Overlay View

Hmm, I am trying to do the same thing. I have the overlayView initialized with a frame size, but I still cant get the button to respond to touches. Is there something else you did as well?

UIView *headsUpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 320)];
		headsUpView.userInteractionEnabled = YES;
		
		
		UIButton *rButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
		rButton.tag = 1;
		rButton.frame = CGRectMake(240, 405, 20, 30);
		[rButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
		[headsUpView addSubview:rButton];

Make sure you add the button to the overlay view after calling setCameraOverlayView. For an example, see Examples/FullScreenCameraExampleController.m at master from pmark's Helpful-iPhone-Utilities - GitHub

Also, did you mean to make your headsUpView be landscape?

The button in the overlayView still doesn't work - so I guess I havent understood your advice properly, this is my code now adding the subview with the button after I add the overlay to the camera:

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
		
		UIView *headsUpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 320)];
		headsUpView.userInteractionEnabled = YES;
	
		[camera setSourceType:UIImagePickerControllerSourceTypeCamera];
		camera.showsCameraControls = NO;
		camera.navigationBarHidden = YES;
		camera.toolbarHidden = YES;
		camera.wantsFullScreenLayout = YES;
		camera.cameraViewTransform = CGAffineTransformScale(camera.cameraViewTransform, 1.0, 1.13);
		camera.cameraOverlayView = headsUpView;
		[self presentModalViewController:camera animated:YES];
		[self.view bringSubviewToFront:headsUpView];
		
		UIButton *rButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect]retain];
		rButton.tag = 1;
		[rButton setTitle:@"Button" forState:UIControlStateNormal];		
		rButton.frame = CGRectMake(240, 405, 50, 70);
		[rButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
		[headsUpView addSubview:rButton];
		
		
	}

This example saves photo only with 320*480 screen! How can I save photos with a bigger resolution (1200*1600)?

Thanks in advance.

You might want to check out iPhone Camera Programming Exercises by Norman McEntire. It was very helpful for me, and as I recall shows you specifically how to get the image dimensions from the camera and save the context to the correct size. There is a free viewer for iPhone, so you don't need a Kindle to use it.

I've been trying to add a toolbar with a button onto the overlay view which simply allows me to cancel the camera. I can't figure out why I'm unable to actually trigger the button. I have the toolbar set up along with the button, but I cannot seem to click on the button. My feeling is that it is somehow being hidden.

Has anybody added a simple toolbar to the overlay with a UIBarButton, and if so how?
