I have created a View where the NavigationBar comes from Obj-c(Native code) and the rest of the view comes from React Native.
Now in the react native view, i have a link which should show the content in a new screen with the navigation experience. I am able to show the content but unable to find a way to change navBar title and show back button on the navBar.
Can you please let me know how we can get access to NavigationBar(Obj-c) in ReactNative?
I don't believe React Native supports this. You cannot take an object created in one language and access it in another. It would be a better idea to create your navigation bar in your JS and use it throughout your app. That even allows you to propagate that UI to your android apps.

I am creating a React native application with the following scenario:
There is a navigation bar at the bottom of the screen, allowing the user to navigate between three main pages. On one of these pages, there is a backdrop with a container overlayed on it with two buttons. Each of these buttons should show open different "pages" in that container, and the navigation bar will be hidden when the user opens one of those "pages". An image is included below.
App layout example
My question is: how is this best implemented in react native?
My original idea was to implement a custom Stack Navigator with createStackNavigator. While this does work, I was wondering if this is a good way to go about it.
One result from using a custom navigator is that the navigation state in the container is also bound to the back button of the device (on Android). However, this is a welcome feature in this case as it makes sense in the navigation flow.
I have a react native app that we are implementing the react native web version using: React native web, the app uses the latests react native navigation library.
So far, mostly everything is working except for modals, the problem that i have is that when i open a modal, the URL path on web updates (I.E: from /signup if i open a modal it switch to /legalAgreementModal?QUERY_PARAMS....), so if i refresh the page the modal works but i can't close the modal anymore. I thought about adding a conditional on the modal to goBack if there is anything to go back to, but the problem is that i have too many modals that can go back to different screens so it will be a huge change if i have to add that logic to every modal.
My question is, is there a way to avoid modals to update my path? So if user refresh they lost the modal but they are on the original screen? Perhaps another workaround that you guys may know could help also!.
Thanks!
I tried adding a conditional on modal close action, adding empty string as the modal path.
I want to show which page is currently opened by the user in the sidebar in a React Native app, which incorporates React Navigation (v1.5).
I want to implement something like this image in my application.
I've tried doing this using this.props.navigation.state (reference) which shows current states/routes in the app, but that didn't worked out for me.
Someone suggested to use global variable in React Native but that was again disappointing.
Kindly help me with that.
The Yelp app for iOS is designed such that after you enter and send a search query, something like this comes up:
The screen consists of a map control in the background, with a screen on top displaying a list view that you can swipe up/down depending on whether you want to see the list/map (respectively).
How would something like this be accomplished using React Native? For example, would the React Navigation or React Native Swiper libraries help me superimpose a list view on top of the map control?
You can use PanResponder.

i am currently working on an App for Android and iOS - i am using react native.
Is there any way to hide the navigation bar dynamically in react-navigation or should i rather switch to react native router flux?
When the user changes to landscape i want to hide the navigation bar, when he goes back to Portrait, i want to show it again.
I know how to change it statically by using {header: null} in the navigation Options, but this does not help me in this case, at least i did not find a way to solve this.
Thanks in advance!
This is sort of a hack but I think you can replace the provided header component from React navigation with your own, then add a redux state that controls its visibility.
Either wrap your screens with a view that contains an onLayout event that will trigger redux action to set the visibility of your custom header.
