    On iPhone and iPod touch, the presented view is always full screen

    If you want to embed image picker, you should manually add its view to one of your other views.

    like this

    [self.view addSubview:self.imagePickerController.view];
    

    I experimented with the code from my last post, and commented out the final scale transform ((the one which makes it full size) and I ended up with a lovely miniature camera imagePicker floating in the middle of my screen, so it definitely does work! The exact code I used, including the zoom/fade-in transition, is -

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.delegate = self;
    imagePickerController.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
    
    UIView *controllerView = imagePickerController.view;
    controllerView.alpha = 0.0;
    controllerView.transform = CGAffineTransformMakeScale(0.5, 0.5);
    
    [[[[UIApplication sharedApplication] delegate] window] addSubview:controllerView];
    
    [UIView animateWithDuration:0.3
              delay:0.0
            options:UIViewAnimationOptionCurveLinear
         animations:^{
             controllerView.alpha = 1.0;
         }
         completion:nil
    ];
    [imagePickerController release];
