Камера не показывает кнопку сохранения/отмены после захвата?

Я использую UIImagePickerController для открытия камеры в своем приложении, и она не показывает кнопку сохранения и отмены вместе с кнопкой захвата.Камера не показывает кнопку сохранения/отмены после захвата?

Для реализации этого я использую объектив-c.

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    pickernew = [[UIImagePickerController alloc] init]; 
    pickernew.sourceType = UIImagePickerControllerSourceTypeCamera; 
    pickernew.delegate = self; 
    pickernew.allowsEditing = YES; 
    [self.view addSubview:pickernew.view]; 
    deviceOrientationCameraLoad=[UIApplication sharedApplication].statusBarOrientation; 
    //nidhi 
    [pickernew setShowsCameraControls:YES]; 

}

Это довольно много кода, чтобы свалить на вопрос здесь. Можете ли вы урезать пример в случае меньшего размера, который по-прежнему имеет ту же проблему? – halfer

Кнопка сохранения/отмены является частью разрешенийEditing, она появляется только после захвата. Кроме того, вы не должны использовать self.view addSubview, , а скорее:

[self presentViewController:pickerView animated:YES completion:nil]

дает эту ошибку: --- Нет видимого @interface для 'CameraViewController' объявляет селектор 'presentViewController: анимированный:' –

Iv'e отредактировал мой ответ, забыли часть «завершение: ноль» – unkgd

Тем не менее он находится в том же состоянии ... не отображать кнопку сохранения/отмены после захвата. –

Камера не показывает кнопку сохранения/отмены после захвата?
