Using Native Popovers/Modals

[JoeStanton]

I'm now trying to wrap the native Image Picker (UIImagePickerController), which is working. I'm wondering though, what is the recommended way to push and pop views on and off the screen?

My current code:

@implementation RCTPhotoManagerDelegate
  - (void) show:(RCTResponseSenderBlock)callback {
      self.done = callback;
      _picker = [[UIImagePickerController alloc] init];
      _picker.modalPresentationStyle = UIModalPresentationCurrentContext;
      _picker.delegate = self;
      _picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
      dispatch_async(dispatch_get_main_queue(), ^{
          UIViewController *root = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
          [root presentViewController:_picker animated:YES completion:nil];
      });
  }

   - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
       self.done(@[[NSString stringWithFormat:@"%@", [info valueForKey: @"UIImagePickerControllerReferenceURL"]]]);
       [self dismissViewControllerAnimated:YES completion:nil];
   }
@end

Currently my popover doesn't actually dismiss, and I feel like this might mess up the React rendering. Is this a bad way to do it?

The reason it doesn't work is because you present the picker from the main window's root view controller, but try to dismiss the picker from self.

You're right, sorry about that, I thought it would be something more specific to React. There seem to be no ill effects in doing this. Thanks!

This is similar to how we do some of our integrations in the groups app, like reuse of the sticker store, photo picker, and composer from the main Facebook app.

I'm also trying to implement something like this with little to no knowledge of Objective-C :)
@JoeStanton could you please share a working example on how to implement a UIImagePickerController ?

+1. Any chance of this? Would be a great to make this into a module.
