iphone - 如何启用 iPhone 相机按钮(缩放、闪光灯、开关)

Question

我正在尝试为我的应用程序使用摄像头，但问题是当我使用此代码时，前置摄像头被禁用:

 ipc.cameraDevice = UIImagePickerControllerCameraDeviceRear;

反之亦然!

  ipc.cameraDevice = UIImagePickerControllerCameraDeviceFront;

我怎样才能同时启用它们？我的意思是启用开关按钮以使用前后摄像头，!!!所有的按钮都被禁用了!变焦、闪光灯、相机开关

代码:

-(IBAction)takePic {


    USImage.hidden = YES;
    ipc = [[UIImagePickerController alloc]init];

    ipc.delegate = self;
    ipc.sourceType = UIImagePickerControllerSourceTypeCamera; 



    ipc.cameraDevice = UIImagePickerControllerCameraCaptureModePhoto;
    ipc.cameraViewTransform = YES;

    [self presentModalViewController:ipc animated:YES];
}

我使用这段代码，它让我可以完美地切换相机:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
