copied!<p>I present a custom camera view controller, onto which I add a "SourceTypeCamera" UIImagePickerController as a contained child view controller. My custom view controller has a button that in turn adds another UIImagePickerController instance, this one a "SourceTypePhotoLibrary".</p> <p>You end up with a nested view controller hierarchy:</p> <ul> <li>root/main view controller <em>— presents:</em></li> <li>my custom camera view controller <em>– adds as child view controller:</em></li> <li><em>either</em> camera <em>or</em> photo-library UIImagePickerController</li> </ul> <p>Something like this:</p> <pre><code>- (void)viewDidLoad { (id<UIImagePickerControllerDelegate,UINavigationControllerDelegate>)theDelegate { [super viewDidLoad]; [self startImagePickerWithSourceType:UIImagePickerControllerSourceTypeCamera delegate:self]; // configure button in camera overlay to call -pickPhotoTapped } - (void) pickPhotoTapped { [self startImagePickerWithSourceType:UIImagePickerControllerSourceTypePhotoLibrary delegate:self]; } - (BOOL) startImagePickerWithSourceType:(UIImagePickerControllerSourceType)sourceType delegate:(id<UIImagePickerControllerDelegate,UINavigationControllerDelegate>)theDelegate { if (([UIImagePickerController isSourceTypeAvailable:sourceType] == NO) || (theDelegate == nil)) return NO; self.cameraUI = [[UIImagePickerController alloc] init]; self.cameraUI.sourceType = sourceType; self.cameraUI.view.frame = self.view.bounds; self.cameraUI.delegate = theDelegate; if (sourceType == UIImagePickerControllerSourceTypeCamera) { self.cameraUI.allowsEditing = NO; self.cameraUI.showsCameraControls = NO; self.cameraUI.cameraOverlayView = [self overlayView]; } [self addChildViewController:self.cameraUI]; [self.view addSubview:self.cameraUI.view]; [self.cameraUI didMoveToParentViewController:self]; return YES; } </code></pre>
