How to lock device orientation for React Native apps (Android & iOS)— 2x02
This story is part of a series where I am sharing my experiences on React Native, hoping it will prove useful to the React Native community and provide helpful insights.
Why lock application orientation mode?
Many applications have their User Interface (UI) designed to contain a lot of elements. To have these applications change their orientation (i.e. from portrait to landscape), it would mean that users will have a bad UI experience and also a lot of scrolling to deal with. A typical example of that case is games.
In these cases, app creators make a decision to visualize this information either vertically or horizontally, not both. Instead they prefer to “lock” orientation to one mode and optimize for it.
How to perform the configuration
There is no exposed API from React Native to achieve that (although there is one from ExpoKit), so in order to achieve our goal we can either configure it directly on the native apps or use third party packages that have been built to help with this purpose, like react-native-orientation.
This article is going to demonstrate how to perform the configuration in the native projects by ourselves; I’m a fan of discovering things in the native realm and delve deeper into them. And in this case it’s really easy and fast to configure it! Let’s see how to achieve this config, for both major platforms:
For Android platform all we need to do is navigate to
AndroidManifest.xml file that lies inside
android/app/src/main path and add the property
android:screenOrientation with a value or
landscape respectively. The property has to be added in xml element activity which is a child of application element.
Simply add it as shown below:
That’s it! Rebuild your project and your are good to go!
For iOS platform we need to open Xcode, and select the desired orientation modes from the Device Orientation section. As shown below: 1. Load the iOS part of your React Native project 2. Navigate to tab General from the horizontal menu 3. Go to down to Deployment Info section and check/uncheck the desired device orientation modes.
And you are set! Rebuild your project to verify that the changes are configured. And of course don’t forget to commit the code changes that were produced from this configuration setup:
