UIImagePickerController在不应该解雇的时候解雇

Question

我正在尝试创建自定义相机叠加层，但遇到了一些问题。捕获视图效果很好，但我希望显示另一个视图，用户可以在捕获图像后编辑照片。问题是，拍摄照片时，带照片的视图会自动被取消。我如何解决这个问题，以便在用户拍照后我可以显示另一个视图控制器。

以下是我创建选择器的方法：

self.cameraPicker = [[UIImagePickerController alloc] init];
self.cameraPicker.delegate = self;
self.cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.cameraPicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.cameraPicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
self.cameraPicker.showsCameraControls = NO;
self.cameraPicker.allowsEditing = YES;
self.cameraPicker.navigationBarHidden = YES;
self.cameraPicker.toolbarHidden = YES;
self.cameraPicker.videoQuality = UIImagePickerControllerQualityTypeIFrame1280x720;
self.frontFacing = NO;
self.gridShowing = NO;
self.showingFlash = NO;


// Insert the overlay
CameraOverlayView *overlay = [[CameraOverlayView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];
self.cameraPicker.cameraOverlayView = overlay;
overlay.delegate = self;

[self.navigationController presentViewController:(UIViewController *)self.cameraPicker animated:YES completion:nil];

以下是我拍照的方法，在调用之后，viewController被解雇： ，我不想要：     [self.cameraPicker takePicture];
