Facebook SDK 3.1 - com.facebook.sdk Error 5 when authenticating with [facebook authorize:permissions]
提问by Atahan Bozkurt
When authenticating with following authorization method i'm getting com.facebook.sdk error 5 with startWithGraphPath and startForMeWithCompletionHandler but not with requestWithGraphPath. I'm succesfully getting token (printing in didLogin) and getting anything which i want with requestwithGraphPath but i'm unable to get work with other methods. If anybody encountered with same issue or something similar or has any idea, i'd be happy if you share it.
当使用以下授权方法进行身份验证时，我使用 startWithGraphPath 和 startForMeWithCompletionHandler 获得 com.facebook.sdk 错误 5，但使用 requestWithGraphPath 时却没有。我成功地获得了令牌（在 didLogin 中打印）并通过 requestwithGraphPath 获得了我想要的任何东西，但我无法使用其他方法。如果有人遇到相同的问题或类似的问题或有任何想法，如果您分享它，我会很高兴。
Thanks
谢谢
Method:
方法：
NSArray *permissions = [[NSArray alloc] initWithObjects: @"user_likes",@"offline_access",@"read_stream",@"publish_stream",nil];
[_facebook authorize:permissions];

Following solution worked for me. But if you're storing a permanent access token, you need to be sure user not removed application permissions otherwise it will give an error. And you can check that with requestWithGraphPath -> "me/permissions".
以下解决方案对我有用。但是，如果您要存储永久访问令牌，则需要确保用户没有删除应用程序权限，否则会出错。您可以使用 requestWithGraphPath -> "me/permissions" 进行检查。
Application Init Function (e.g.:didFinishLaunchingWithOptions/or where you init your Facebook object which needs to be fbsessiondelegate in the mean time)
应用程序初始化函数（例如：didFinishLaunchingWithOptions/或者你在哪里初始化你的 Facebook 对象，它需要同时是 fbsessiondelegate）
...
NSArray* permissions = [[NSArray alloc] initWithObjects:@"user_likes",@"offline_access", nil];
FBSession*oursession = [[FBSession alloc] initWithPermissions:permissions];
...
FBDidLogin function:
FBDid登录功能：
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
[defaults synchronize];
Example graph api request function:
图 api 请求函数示例：
NSUserDefaults *userDefaults =[NSUserDefaults standardUserDefaults];
NSString *key = [userDefaults stringForKey:@"FBAccessTokenKey"];
FBRequest* ourcon = [[FBRequest alloc] initWithSession:oursession graphPath:@"me/likes" parameters:params HTTPMethod:@"GET"];
[ourcon startWithCompletionHandler: ^(FBRequestConnection *connection, id<FBGraphUser> result, NSError *error){
if(error)
{
//NSLog(error.code);
return;
}
NSArray* collection = (NSArray*)[result data];
NSLog(@"You have %d like", [collection count]);
NSDictionary* name = [collection objectAtIndex:14];
NSLog(@"Like Name: %@", [name objectForKey:@"name"]);
}];

The startWithGraphPath and other start* methods are likely not picking up an active session. Those methods are relying on an active session being set. See:
startWithGraphPath 和其他 start* 方法可能没有选择活动会话。这些方法依赖于正在设置的活动会话。看：
"The request uses the active session represented by [FBSession activeSession]."
“该请求使用由 [FBSession activeSession] 表示的活动会话。”
So you'll have to do something like this:
所以你必须做这样的事情：
[FBSession setActiveSession:session];
Where session is an FBSession that you had previously set up.
其中 session 是您之前设置的 FBSession。
