Starting Screen React Native Screen with Data
I want to get back to Native viewController
from react native Component in iOS
.
In my current project I'm implementing some of the screens with Native code
(Obj C) and some of the screens(like which ever having the graphs and some complex dashboard UI) with React Native using JavaScript
.
I'm pushing the ReactNativeObjCViewController
from ViewConrtoller
and loading the React Native View(Tab bar with Navigation) from ReactNativeObjCViewController
by subclassing the RCTRootView
.
After successful loading of React Native view and showing the proper data according to the implementation. And now I want to go back to native view i.e ViewController
from React Native Component.
Please help me on that.

[[self navigationController] pushViewController:rootViewController animated:YES];
}
