Create react-native project
Use this command to create your new react-native-project
react-native init HelloWorld.
1. Install Android Studio 2. Install the Android SDK 3. Open your android studio, file-> open -> and browse to your project folder HelloWorld-> android 4. Run the app from Run-> Run ‘app’
You can change your app name by editing app_name in the strings.xml file. app/src/main/res/values/strings.xml
You can change the app icon by adding the icons in mipmap-hdpi, mipmap-dpi, mipmap-xhdpi, and mipmap-xxhdpi and change the android:icon=“@mipmap/ic_launcher“
Value in AndroidManifest.xml file
To generate a signed app you need to create a Keystore for your project and keep this Keystore secure. We need this Keystore for further updates of the app.
Build -> Generate Signed app
In the Keystore section create a new one if you don’t have one already or select the path to an existing one.
You need to specify the Keystore password, key password rd, and alias and need to specify one certificate detail for generating a new Keystore.
After that click next and then finish.
Once you have your React Native project initialized, you can run react-native run-ios inside the newly created project directory. If everything is set up correctly, you should see your new app running in the iOS Simulator shortly.
You can specify the device the simulator should run with the –simulator flag, followed by the device name as a string. The default is “iPhone 6″. If you wish to run your app on an iPhone 4s, just run react-native run-ios –simulator=”iPhone 4s”.
1). Plug in your device via USB
Connect your iOS device to your Mac using a USB to Lightning cable. Navigate to the ios folder in your project, then open the .xcodeproj file within it using Xcode.
If this is your first time running an app on your iOS device, you may need to register your device for development. Open the Product menu from Xcode’s menubar, then go to Destination. Look for and select your device from the list. Xcode will then register your device for development.
2). Configure code signing
Register for an Apple developer account if you don’t have one yet.
Select your project in the Xcode Project Navigator, then select your main target (it should share the same name as your project). Look for the “General” tab. Go to “Signing” and make sure your Apple developer account or team is selected under the Team dropdown.
Repeat this step for the Tests target in your project.
3). Build and Run your App.
If everything is set up correctly, your device will be listed as the build target in the Xcode toolbar, and it will also appear in the Devices pane (??2). You can now press the Build and run button (?R) or select Run from the Product menu. Your app will launch on your device shortly.
If you run into any issues, please take a look at Apple’s Launching Your App on Device docs.
Things to Do Before Deployment for IOS
Here is the list of things you should set out to achieve before even thinking of submitting for actual release:
Create the appropriate Apple Developer account (personal or business)
After creating the provisioning certificate, In the Xcode menu, select the device as Generic IOS Device.
Product->Clean and build your application.
If the provisioning certificate is not valid, it will lead to the building failing with an error. If so you have to change it to a valid certificate through your project->build settings. Else if the build succeeded just leave this step.
Then select Product->archive, it will create an archive file in Organiser->archives and open it up for you after the archive is finished.
Once the archive is completed it will open in the Organizer window
Then select the export function from the right side section.
Select a method for export as per your need and click on the Next button.
Then choose your development team to use for provisioning.
Then select the required device support as per your need and click on the Next button.
Then it shows the summary and clicks on the Next button.
Now choose the location where the folder is to be saved and Click on Export
If you want to take diavi build please upload the .ipa file to this site.
If you want to take iTunes build,
Please select open Xcode ->development tool ->Application Loader from Xcode seen in the top left corner of the window
In application Loader choose your development team to use for provisioning from the left top corner and choose the .ipa file from the bottom left side
Submitting the app to iTunes by using the following link.
If we want to take another build or change the version we need to change the build number and version number in the code.
Windows 10:Currently, only Universal Windows Platform (UWP) applications are officially supported. You may be able to do development from an older version of Windows as long as you have a Windows 10 device available to run the application on remotely.
