在iOS中从相机中选取图像时添加图库选项

Question

i want to add camera feature in my app but the default camera view doesn't have the option to select image from the gallery and i am doing this because i don't want to make alert view for the user to select image picker type, ie, camera or photo gallery. how to implement this??

  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];
