title: move and scale bounces back
body: <p>As you can see in <a href="http://www.youtube.com/watch?v=v3cI4nLksBw&amp;9feature=youtu.be" rel="nofollow">this video</a> it bounces back whenever I try to crop or move the crop box.  I can't find any way to do this and I think my code is correct. How am I suppose to do this?  </p>
  
  <pre><code>- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
      UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                            message:@"Device has no camera"
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles: nil];
      [myAlertView show];
    }
  }
  
  - (IBAction)takePhoto:(UIButton *)sender {
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:picker animated:YES completion:NULL];
  }
  
  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.imageView.image = chosenImage;
    [picker dismissViewControllerAnimated:YES completion:NULL];
  }
  </code></pre>
