为什么没有完成finishWithAuth：方法？

Question

I done google integration on my sample app, while i am trying to implement in my project the finishedWithAuth method didn't call.

0.its entering into google+ login screen.

1.i done creating Oauth client key generation.

2.Added gppsigninbutton.

3.in appdelegate.m file

   - (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
   if([FBSDKApplicationDelegate sharedInstance])
   {
        return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                              openURL:url
                                                    sourceApplication:sourceApplication
                                                           annotation:annotation];
   }
   else
   {
       NSLog(@"entering");
        return [GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation];
   }


}

implemented

4. url also added in .plist.

this is my code

      signIn.delegate = self;
    signIn = [GPPSignIn sharedInstance];
    signIn.shouldFetchGooglePlusUser = YES;
    signIn.shouldFetchGoogleUserEmail = YES;
    //signIn.shouldFetchGoogleUserEmail = YES;  // Uncomment to get the user's email

    // You previously set kClientId in the "Initialize the Google+ client" step
    signIn.clientID = kClientId;
    //    signIn.clientID=APIID;
    signIn.homeServerClientID = kClientId;
    // Uncomment one of these two statements for the scope you chose in the previous step
    //    signIn.scopes = @[ kGTLAuthScopePlusLogin ];  // "https://www.googleapis.com/auth/plus.login" scope
//    signIn.scopes = @[ @"profile" ];            // "profile" scope
        signIn.scopes=[NSArray arrayWithObjects:kGTLAuthScopePlusLogin,kGTLAuthScopePlusMe, nil];
    // Optional: declare signIn.actions, see "app activities"


    [signIn trySilentAuthentication];
}
- (void)signOut {
    [[GPPSignIn sharedInstance] signOut];
}

Answer 1

It seems you are using both Facebook and Google+ Sign In. So change your - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation to this:

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


    NSString *stringURL = [ url absoluteString];
    if([stringURL containsString:@"fb"])
    {

    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
    }
    else
    {
        return [GPPURLHandler handleURL:url
                      sourceApplication:sourceApplication
                             annotation:annotation];

    }
}

Also code for loginWithGoogle should look like the following. The problem is with your signIn.scopes .

-(IBAction)loginWithGooglePressed:(id)sender
{
    ///
    signIn = [GPPSignIn sharedInstance];
    signIn.clientID = kClientId;

    //signIn.shouldFetchGooglePlusUser = YES;
    signIn.shouldFetchGoogleUserEmail = YES;  // Uncomment to get the user's email

    signIn.scopes= [NSArray arrayWithObjects:kGTLAuthScopePlusUserinfoEmail, nil];

    // Optional: declare signIn.actions, see "app activities"
    signIn.delegate = self;

    [signIn trySilentAuthentication];

}

Works Fine for me:
