iOS Guide

1. Installation

NOTE react-native-link may add the RNGoogleSignin podspec to your Podfile. If your Podfile looks roughly like the one described here then this is likely what you want, but otherwise you may get stuck with build errors. If your Podfile does not refer to the React podspec, then you probably do not want to use the RNGoogleSignin podspec and we recommend that you rename or delete the RNGoogleSignin.podspec file from node_modules/react-native-google-signin and only then run react-native link react-native-google-signin. This is a one-time operation that you won't need to repeat later. We hope to improve this behavior later on - PRs are welcome.

Link the native module

There are two ways to link the module:

• automatic

1. react-native link react-native-google-signin

• manual

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-google-signin ➜ ios and add RNGoogleSignin.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNGoogleSignin.a to your project's Build Phases ➜ Link Binary With Libraries

Install Google Sign In SDK

Again, we offer two ways to do this: with and without Cocoapods. Note that we require Google Sign In SDK version >= 4.3.0!

With Cocoapods

1. install the Google Signin SDK with CocoaPods: add pod 'GoogleSignIn', '~> 4.4.0' in your Podfile and run pod install

First time using cocoapods ? check this out

At the end, the dependencis should be linked like in this picture (this is with pods).

Without Cocoapods

1. download the GoogleSignIn SDK from here and unzip it. Drag and drop the unzipped .framework files into the Frameworks group in Xcode and copy GoogleSignIn.bundle to your project. During copying, check copy items if needed.
2. make sure GoogleSignIn.bundle is added in your Xcode project's Copy Bundle Resources build phase.

NOTE according to google sign in docs you may also need to do this: In -> Build Phases -> Link binary with libraries step, add libRNGoogleSignin.a, AddressBook.framework, SafariServices.framework, SystemConfiguration.framework and libz.tbd. We have found it not to be necessary for a successful build, but we recommend to follow Google's installation instructions!

At the end, the dependencis should be linked like in this picture (this is without pods).

2. Google project configuration

• Follow this guide to get the configuration file.

• Download the GoogleService-Info.plist file at the end of the process

3. XCode configuration

• Configure URL types in the Info panel (see screenshot)
  • add a URL with scheme set to your REVERSED_CLIENT_ID (found inside GoogleService-Info.plist)

Modify your app to respond to the URL scheme (optional)

This is only required if you have multiple listeners for openURL - for instance if you have both Google and Facebook OAuth.

Because only one openURL method can be defined, if you have multiple listeners for openURL, you must combine them into a single function in your AppDelegate.m like so:

• Open AppDelegate.m
• Add an import: #import <RNGoogleSignin/RNGoogleSignin.h> (if this one will not work try #import "RNGoogleSignin.h"). If this file cannot be found, you need to modify your header search paths so Xcode can find headers of react-native-google-signin. For example, when using the non-cocoapods installation, make sure that $(SRCROOT)/../node_modules/react-native-google-signin/ios is included in your target's header search paths.
• Add a method to respond to the URL scheme:

// AppDelegate.m
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] annotation:options[UIApplicationOpenURLOptionsAnnotationKey]]
         || [RNGoogleSignin application:application openURL:url sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}

If you're targeting iOS 9 or newer, you'll want to use the application:openURL:options: method as shown in the following snippet:

- (BOOL)application:(UIApplication *)application openURL:(nonnull NSURL *)url options:(nonnull NSDictionary<NSString *,id> *)options {
  return [RNGoogleSignin application:application
                             openURL:url
                   sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                          annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}

You may also use the deprecated application:openURL:sourceApplication:annotation: method:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

  return [RNGoogleSignin application:application
                             openURL:url
                   sourceApplication:sourceApplication
                          annotation:annotation
          ];
}
