React-Native iOS - How can I navigate to a non-React-Native view (native iOS view controller) from a React-Native view with a button press?

Question

The RN doco and other examples show how to launch a React-Native view from a native iOS view controller, but not the other way around. Can someone explain how I can do this

Answer 1

There is little improvement on this solution.With present solution there is no way to come back to React-Native from iOS. 

If you want to come back again from iOS to React-Native.Do the below

 // AppDelegate.h

    - (void) goToNativeView {
     UIViewController *vc =  [InitialViewController new];// This is your native iOS VC
     UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:vc];

      dispatch_async(dispatch_get_main_queue(), ^{
       // Never do the below, it will be difficult to come back to react-native

       // self.window.rootViewController = navigationController;

        // Do this instead
        [self.window.rootViewController presentViewController:navigationController animated:true completion:NULL];
      });
    }

//InitialViewController.m

    **-Create a button for go back to React-native and on button action dismiss this view controller like below.**

    // Dismiss the VC so controll go back from iOS to react-native
        [self dismissViewControllerAnimated:TRUE completion:nil];
