– （void）finishedWithAuth：（GTMOAuth2Authentication *）auth error：（NSError *）error – Method is not call

我想获取用户在我的应用中使用Google+登录的所有信息。

-(void)googleSignInButtonMethod{ [[UIApplication sharedApplication] delegate]; signIn = [GPPSignIn sharedInstance]; signIn.clientID = kClientId; [signIn authenticate]; signIn.shouldFetchGoogleUserID=YES; signIn.shouldFetchGoogleUserEmail = YES; signIn.scopes = @[ kGTLAuthScopePlusLogin ]; signIn.delegate = self; [signIn authenticate]; } 

之后，

 - (void)finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error { NSLog(@"Received Error %@ and auth object==%@",error,auth); if(!error) { NSLog(@"%@", signIn.authentication.userEmail); } } 

我按照谷歌+开发者网站提供的所有说明进行操作。 我设置了所有委托并导入了所有重要文件。

在.h文件中

 @property (weak, nonatomic) IBOutlet GIDSignInButton *gmailSignInButton; -(IBAction)gmailBtn:(GIDSignIn *)sender; 

在.m文件中

 - (IBAction)gmailBtn:(GIDSignIn *)sender { [[AFNetworkReachabilityManager sharedManager]startMonitoring]; //Checking the Internet connection... [[AFNetworkReachabilityManager sharedManager]setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status){ if (status == AFNetworkReachabilityStatusReachableViaWWAN || status == AFNetworkReachabilityStatusReachableViaWiFi) { [GIDSignIn sharedInstance].uiDelegate = self; [[GIDSignIn sharedInstance] signIn]; }else{ NSLog(@"No Network"); } }]; } - (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error { // Perform any operations on signed in user here. NSLog(@"user ID: %@",user.userID); NSLog(@"user Token: %@",user.authentication.idToken); NSLog(@"user name: %@",user.profile.name); NSLog(@"user givenName: %@",user.profile.givenName); NSLog(@"user family Name: %@",user.profile.familyName); NSLog(@"user email: %@",user.profile.email); NSURL *profileURL; if (user.profile.hasImage) { profileURL = [user.profile imageURLWithDimension:100]; } NSMutableDictionary *userData = [NSMutableDictionary dictionary]; [userData setValue:user.userID forKey:@"id"]; [userData setValue:user.profile.givenName forKey:@"first_name"]; [userData setValue:user.profile.familyName forKey:@"last_name"]; [userData setValue:@"" forKey:@"gender"]; [userData setValue:user.profile.email forKey:@"email"]; [userData setValue:profileURL forKey:@"profileImg"]; } - (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error{ // [self presentViewController:viewController animated:YES completion:nil]; } - (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController { [self presentViewController:viewController animated:YES completion:nil]; } // Dismiss the "Sign in with Google" view - (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController { [self dismissViewControllerAnimated:YES completion:nil]; } 

*不要忘记声明gmail委托GIDSignInUIDelegate，GIDSignInDelegate
