1: There are two ways to Integrate the Application with google sign in. (Using cocoa pod and manual);
2: Here I am mentioning manual way.
3: Download the Google SDK from that site. (https://developers.google.com/identity/sign-in/ios/sdk/)
4: Extract the SDK archive you downloaded and copy the following files to your Xcode project:
GoogleSignIn.frameworkGoogleSignIn.bundleGoogleSignIn.bundle to your Xcode project’s Copy Bundle Resources build phase.5: Link the dependent framework in Xcode.
AddressBook.frameworkSafariServices.frameworkSystemConfiguration.framework6: set other linker flags in build setting
$(OTHER_LDFLAGS) -ObjC7: Get the Configuration file by clicking that URL : (https://developers.google.com/mobile/)
8: Enter App name and bundle Id so it will create .plist file so you have to drag into your xcode as root.
9: add the following Data :
Also, you will need to set the client ID directly using the value found in the GoogleService-Info.plist file:
|
1 2 |
<code><span class="pun">[</span><span class="typ">GIDSignIn</span><span class="pln"> sharedInstance</span><span class="pun">].</span><span class="pln">clientID </span><span class="pun">=</span><span class="pln"> kClientID</span><span class="pun">;</span> </code> |
10 : Do some changes in App delegate file :

#import "AppDelegate.h" #import <GoogleSignIn/GoogleSignIn.h> @interface AppDelegate () @end @implementation AppDelegate static NSString * const kClientID = @"442678058869-fto2clbuonqr1au1laa2u23fnji0h454.apps.googleusercontent.com"; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. [GIDSignIn sharedInstance].clientID = kClientID; return YES; } - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation]; } |
here kClientId is client id of generated configuration .plist file.
11: Now to draw the google sign in button so here I am taking a view controller to display all that things.
a: viewcontroller.m class

12: Now, at last, you have to change your own project info.plist file.
In the Project > Target > Info > URL Types panel, create a new item and paste yours REVERSED_CLIENT_ID into the URL Schemes field. You can find yours REVERSED_CLIENT_ID in the GoogleService-Info.plist file.
13: Now Run.
14: You can also download sample apps go to https://github.com/googlesamples/google-services/tree/master/ios/signin/SignInExample .
