Answer 1

You can add your own button instead of using Google Sign-In button Do follwing things

1)Add this code in AppDelegate.m file

2)Add your own button into storyBoard and give class name as GPPSignInButton and set UIImageView on that button.

3)drag action into viewController

AppDelegate.m file

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    GPPSignIn *SignIn = [GPPSignIn sharedInstance];

    [GPPSignIn sharedInstance].clientID = @"532796865439-juut4g2toqdfc13mgqu5v9g5cliguvmg.apps.googleusercontent.com";

    SignIn.scopes = @[kGTLAuthScopePlusLogin];
    return YES;
} 

-(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    if ([GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation]) {

        return YES;
    }

    return wasHandled;
}




ViewController.m file

@property (strong, nonatomic) IBOutlet GPPSignInButton *btn;

- (void)viewDidLoad {
    [super viewDidLoad];

   [GPPSignIn sharedInstance].delegate = self;
    [[GPPSignIn sharedInstance] trySilentAuthentication];

    AppDelegate *appDelegate = (AppDelegate *)
    [[UIApplication sharedApplication] delegate];
  }



-(void) finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error
{
    GPPSignIn *signIn = [GPPSignIn sharedInstance];
    signIn.shouldFetchGoogleUserEmail = YES;
    signIn.delegate = self;

    if (error == nil) {
        if(auth.canAuthorize){
            GTLServicePlus *service = [[GTLServicePlus alloc] init];
            [service setRetryEnabled:YES];
            [service setAuthorizer:auth];

            GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:@"me"];


            // 1. Create a |GTLServicePlus| instance to send a request to Google+.
            GTLServicePlus* plusService = [[GTLServicePlus alloc] init] ;
            plusService.retryEnabled = YES;

            // 2. Set a valid |GTMOAuth2Authentication| object as the authorizer.
            [plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];

            // 3. Use the "v1" version of the Google+ API.*
            plusService.apiVersion = @"v1";
            [plusService executeQuery:query
                    completionHandler:^(GTLServiceTicket *ticket,
                                        GTLPlusPerson *person,
                                        NSError *error) {
                        if (error) {
                            //Handle Error
                        } else {
                            NSLog(@"\nEmail= %@", [GPPSignIn sharedInstance].authentication.userEmail);
                            NSLog(@"\nGoogleID=%@", person.identifier);
                            NSLog(@"\nUser Name=%@", [person.name.givenName stringByAppendingFormat:@" %@", person.name.familyName]);
                            NSLog(@"\nGender=%@", person.gender);
                        }
                    }];

        }
    }
}
