iphone - 在ios中从相机中选择图像时添加图库选项

Question

我想在我的应用程序中添加相机功能，但默认相机视图没有从图库中选择图像的选项，我这样做是因为我不想让用户选择图像选择器类型的警报视图，即，相机或照片库。如何实现这个？

  UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
   [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];

   imagePicker.showsCameraControls = NO;
   imagePicker.navigationBarHidden = YES;

   imagePicker.wantsFullScreenLayout = YES;
   imagePicker.cameraOverlayView = overlayView;

Answer 1

UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
    [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
