AVCaptureVideoOrientation Querformat Ergebnis in upside-down-Standbilder

Im mit AVCaptureSession für die Aufnahme von Bildern und speichern von Bildern zum album. Wenn ich auf die Schaltfläche klicke, nimmt es den snapshot und speichern album. Aber wenn ich landscape-Modus, klicken Sie dann auf die Schaltfläche speichert Querformat Ergebnis in upside-down-Standbilder.

code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    //Do any additional setup after loading the view.

    [self setCaptureSession:[[AVCaptureSession alloc] init]];


    [self  addVideoInputFrontCamera:NO]; //set to YES for Front Camera, No for Back camera

    [self  addStillImageOutput];

    [self setPreviewLayer:[[AVCaptureVideoPreviewLayer alloc] initWithSession:[self captureSession]] ];

      [[self previewLayer] setVideoGravity:AVLayerVideoGravityResizeAspectFill];

      CGRect layerRect = [[[self view] layer] bounds];


    [[self previewLayer]setBounds:layerRect];
    [[self  previewLayer] setPosition:CGPointMake(CGRectGetMidX(layerRect),CGRectGetMidY(layerRect))];
    [[[self view] layer] addSublayer:[self  previewLayer]];

     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(saveImageToPhotoAlbum) name:kImageCapturedSuccessfully object:nil];


    [[self captureSession] startRunning];

camera=[UIButton buttonWithType:UIButtonTypeCustom];
[camera setImage:[UIImage imageNamed:@"button.png"] forState:UIControlStateNormal];
[camera setFrame:CGRectMake(150, 10, 40, 30)];
[camera addTarget:self action:@selector(takephoto:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:camera];

}

Taste für die Aufnahme von Bild:

-(void)takephoto:(id)sender{

[self captureStillImage];

}

- (void)captureStillImage

    AVCaptureConnection *videoConnection = nil;
    for (AVCaptureConnection *connection in [[self stillImageOutput] connections]) {

            }
        }
