ios - Capture and custom crop image with camera iOS

Question

I am using UIImagePickerController to capture the image. Now I want to crop the image. I am using cameraOverlayView method of UIImagePicker but it does not allow to move my cropping view. I want my cropping view should be moveable and resizable so that user can select image portion to use. I am using the following code:

UIImagePickerController *cameraPicker = [[UIImagePickerController alloc] init];
            cameraPicker.delegate = self;
            cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            cameraPicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
            UIView *overlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
            cameraPicker.cameraOverlayView =overlay;
            cameraPicker.allowsEditing = NO;
            [self presentViewController:cameraPicker animated:YES completion:nil];

Can anyone suggest what can I do?

Answer 1

- (void)pickphoto:(UIImagePickerControllerSourceType)sourceType
{
    imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.navigationBar.tintColor=[UIColor blackColor];
    imagePicker.navigationItem.title=@"Photo Albums";
    imagePicker.AllowsEditing = TRUE;
    imagePicker.delegate = self;
    imagePicker.sourceType = sourceType;

    [self presentModalViewController:imagePicker animated:YES];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{

    _imageV.image = image;
    _imageV.layer.borderColor=[UIColor whiteColor].CGColor;
    _imageV.layer.borderWidth=1.0;
    [imagePicker dismissModalViewControllerAnimated:YES];
}
