Facebook在iOS上登录错误的应用程序

Question

我的iOS应用程序使用Facebook登录,但我的开发团队最近决定将我们的所有应用程序整合到一个具有通用APP ID的通用Facebook应用程序中.所以我进入我的项目并尝试将我的FacebookAppID和URL类型更改为正确的APP ID,但是当我运行应用程序并单击登录按钮时,它会重定向我以登录我在Facebook上的旧应用程序.我完全不知道为什么会这样,但这是我在AppDelegate文件中的内容:

/*
 Callback for session changes
*/
- (void)sessionStateChanged:(FBSession *)session
                  state:(FBSessionState) state
                  error:(NSError *)error
{
switch (state) {
    case FBSessionStateOpen:
        if (!error) {
            // We have a valid session
            NSLog(@"User session found");
        }
        break;
    case FBSessionStateClosed:
    case FBSessionStateClosedLoginFailed:
        [FBSession.activeSession closeAndClearTokenInformation];
        break;
    default:
        break;
}

[[NSNotificationCenter defaultCenter]
 postNotificationName:FBSessionStateChangedNotification
 object:session];

if (error) {
    UIAlertView *alertView = [[UIAlertView alloc]
                              initWithTitle:@"Error"
                              message:error.localizedDescription
                              delegate:nil
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
    [alertView show];
    }
}

/*

- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
    NSArray *permissions = [[NSArray alloc] initWithObjects:
                        @"email",
                        @"user_games_activity",
                        @"user_location",

                        @"user_birthday",
                        nil];
return [FBSession openActiveSessionWithReadPermissions:permissions
                                          allowLoginUI:allowLoginUI
                                     completionHandler:^(FBSession *session,
                                                         FBSessionState state,
                                                         NSError *error) {
                                         [self sessionStateChanged:session
                                                             state:state
                                                             error:error];
                                     }];
}

/*

- (BOOL)application:(UIApplication *)application
        openURL:(NSURL *)url

     annotation:(id)annotation {
    // attempt to extract a token from the url
    return [FBSession.activeSession handleOpenURL:url];
}
/*

- (void) closeSession {

Answer 1

您的设备上可能有两个应用程序Info.plist中具有相同Facebook URL方案的应用程序.你可以:

• 删除旧的应用程序,或
• 重新安装旧应用程序,但事先从Info.plist文件中删除Facebook URL方案

您可能有多个URL方案.如果是这样,您应该查找看起来像fbxxxxxxxxxxx的那个,它显示在http://developers.facebook.com/上的应用页面上
