Question

I have an app that loads the camera and overlays buttons for fire, reload, and back, as well as a png that animates when the fire and reload buttons are tapped. How would I load the View Controller, which has a .xib with the buttons and image, as an overlay when the camera view loads?

I have the camera view loading when a button on the main screen is tapped, which used to open another View with the buttons and gun image.

Below is what I have done so far, which is loading the camera. I have a separate View Controller named PlayViewController, with an xib for the interface:

-(IBAction)getCameraPicture:(id)sender {


UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

PlayViewController* overlay = [[PlayViewController alloc] initWithNibName:@"PlayViewController" bundle:nil];
picker.cameraOverlayView = overlay.view;
[picker setDelegate:overlay];
[self presentModalViewController:picker animated:YES];

}
This is in the PlayViewController.m: code

   #import "PlayViewController.h"
   #import "SoundViewController.h"

@interface PlayViewController ()

@end

@implementation PlayViewControlleriPad...

`

PlayViewController.h:

@interface PlayViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{

two array declarations...

}

@property (weak, nonatomic) IBOutlet UIButton *reloadButton;
@property (weak, nonatomic) IBOutlet UIButton *fireButton;
@property (weak, nonatomic) IBOutlet UITextField *ammoField;
@property (weak, nonatomic) IBOutlet UIImageView *type;

@end

Create your view controller and xib as usual, then add this to your code:

YourOverlay* overlay = [[YourOverlay alloc] initWithNibName:@"YourOverlayView" bundle:nil];
picker.cameraOverlayView = overlay.view;
[picker setDelegate:overlay];
[self presentModalViewController:picker animated:YES];

The overlay must implement UIImagePickerControllerDelegate and UINavigationControllerDelegate
