每次打开相机时都不使用UIImageViewController cameraDevice

Question

我希望我的应用程序只使用前置摄像头.所以我已经实现了以下代码.

if ([UIImagePickerControllerisCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront]) {
   self.imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;
}

这是我第一次打开相机时(它使用前置摄像头).但如果我取消照片然后重新进入相​​机,它将使用后置摄像头.

每次取消/重新进入相​​机时,它会在前后摄像头之间切换......

有什么我想念的吗？

Tr this code .I used this code and it is working fine .Use this code either in button action or viewwillappear or viewdidload and dismiss the camera view properly
    imgPicker =[[UIImagePickerController alloc] init];
    imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imgPicker.cameraDevice=UIImagePickerControllerCameraDeviceFront;
    imgPicker.showsCameraControls = YES;
    imgPicker.allowsEditing = YES;
    imgPicker.delegate=self;
    [self presentViewController:imgPicker
                       animated:NO completion:nil];
