whyWithAuth：方法沒有調用？

Question

我完成了谷歌在我的示例應用程序集成，而我試圖在我的項目中落實finishedWithAuth方法沒有調用。

0.its進入google +登錄屏幕。

1.i完成創建Oauth客戶端密鑰生成。

2.增加了gppsigninbutton。

3.in appdelegate.m文件

- (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]; 
    } 


} 

實施

URL也加入的.plist。

這是我的代碼

 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]; 
} 
- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth 
        error: (NSError *) error { 
    NSLog(@"Received error %@ and auth object %@",error, auth); 
    if(error) 
    { 

    } 
    else 
    { 
     NSString *serverCode = [GPPSignIn sharedInstance].homeServerAuthorizationCode; 
     NSLog(@"this is server code%@",serverCode); 
     NSLog(@"user email%@", signIn.authentication.userEmail); 
     NSLog(@"user id%@",signIn.authentication.userID); 
     NSLog(@"auth token=%@",auth.accessToken); 
     NSString *str = [NSString stringWithFormat:@"https://www.googleapis.com/oauth2/v1/userinfo?access_token=%@",auth.accessToken]; 
     NSString* escapedUrl = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
     NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",escapedUrl]]; 
     NSString *jsonData = [[NSString alloc] initWithContentsOfURL:url usedEncoding:nil error:nil]; 
     NSData *data = [jsonData dataUsingEncoding:NSUTF8StringEncoding]; 
     id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; 



     NSLog(@"this is jsonvalues==%@",json); 
     if (auth.userEmail) 
     { 
      [[[GPPSignIn sharedInstance] plusService] executeQuery:[GTLQueryPlus queryForPeopleGetWithUserId:@"me"] completionHandler:^(GTLServiceTicket *ticket, GTLPlusPerson *person, NSError *error) 
      { 
       // NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",person.image.url]]; 
       // NSLog(@"%@",url); 
       // NSLog(@"Name:%@",person.displayName); 
       //     NSLog(@"birthday:%@",person.birthday); 
       // 
       //     NSLog(@"gender:%@",person.gender); 
       NSLog(@"peoplelist%@",person.displayName); 
       NSLog(@"peopleimae=%@",person); 
       //     NSLog(@"people image%@",person.image); 
       //     NSLog(@"people emailid%@",person.emails); 
       //     imgurl = userData[@"picture"][@"data"][@"url"]; 
       NSDictionary *dic=(NSDictionary *)person; 
       if(person.image) 
       { 
        NSLog(@"this is converted dictionary=%@",dic); 
       } 
      }]; 
//   [self disconnect]; 
     } 
    } 
} 
- (void)disconnect { 
    [[GPPSignIn sharedInstance] disconnect]; 
} 
- (void)didDisconnectWithError:(NSError *)error { 
    if (error) { 
     NSLog(@"Received error %@", error); 
    } else { 
     // The user is signed out and disconnected. 
     // Clean up user data as specified by the Google+ terms. 
    } 
} 

Answer 1

似乎你同時使用Facebook和Google+登錄。因此，改變你的- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation這樣的：對於loginWithGoogle

- (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]; 

    } 
} 

而且代碼應如下所示。問題出在您的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]; 

} 

正常工作對我來說：
