Facebook SDK 4.x权限问题iOS

本文介绍了Facebook SDK 4.x权限问题iOS的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试为登录用户的时间轴获取 Feed 。我有一个登录按钮，我传递读取权限，包括 user_posts 。令人惊讶的是，Facebook没有授予我这个许可并忽略它。

代码：

- （void）viewDidLoad { [super viewDidLoad]; //加载视图后通常从一个笔尖进行任何其他设置。 self.loginButton.readPermissions = @ [@public_profile，@email，@user_friends，@user_posts]; self.loginButton.delegate = self; if（[FBSDKAccessToken currentAccessToken]） { NSLog（@有访问令牌）; NSLog（@permissions ....％@，[FBSDKAccessToken currentAccessToken] .permissions）; [self retrieveFeed]; } #pragma标记 - 登录代理 - （void）loginButton：（FBSDKLoginButton *）loginButton didCompleteWithResult :( FBSDKLoginManagerLoginResult *）结果错误：（NSError *）错误 { NSLog（@登录成功!!）; NSLog（@permissions ....％@，[FBSDKAccessToken currentAccessToken] .permissions）; [self retrieveFeed]; } - （void）loginButtonDidLogOut：（FBSDKLoginButton *）loginButton { } #pragma mark - 接收FB Feed - （void）retrieveFeed { FBSDKGraphRequest * request = [[FBSDKGraphRequest alloc] initWithGraphPath：@/ me / feed参数：nil ]。 FBSDKGraphRequestConnection * connection = [[FBSDKGraphRequestConnection alloc] init]; [connection addRequest：request completionHandler：^（FBSDKGraphRequestConnection * connection，id result，NSError * error）{ NSLog（@％@，result）; if（error） NSLog（@Some error FEED ;;;;;％@，error.localizedDescription）; }]; [连接开始]; }

点击登录按钮，我获得以下权限屏幕。 Facebook已经忽略了 user_posts 权限。

即使我尝试在登录后再获得此权限，Facebook告诉我，我有已经授权的应用程序这样做，即使有不允许这样的权限！获取新权限的代码是：

- （void）checkForFeedPermission { if（[[ FBSDKAccessToken currentAccessToken] hasGranted：@user_posts]）{ NSLog（@已批准Feed访问）; [self retrieveFeed]; } else { FBSDKLoginManager * loginManager = [[FBSDKLoginManager alloc] init]; [loginManager logInWithReadPermissions：@ [@user_posts] handler：^（FBSDKLoginManagerLoginResult * result，NSError * error）{ NSLog（@requests feed access）; [self retrieveFeed]; }]; } }

我在这个问题上一直在三回头天。请建议我哪里可以出错？谢谢。

解决方案

我认为不适用于$ user_posts 可能是你可以在loginTime设置此权限

I am trying to get Feed for logged in user's timeline. I have a login button, to which I am passing read permissions including user_posts. Amazingly, Facebook does not grant me this permission and ignores it.

Code:

- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.loginButton.readPermissions = @[@"public_profile", @"email", @"user_friends", @"user_posts"]; self.loginButton.delegate = self; if([FBSDKAccessToken currentAccessToken]) { NSLog(@"Have access token"); NSLog(@"permissions .... %@",[FBSDKAccessToken currentAccessToken].permissions); [self retrieveFeed]; } } #pragma mark - Login Delegate -(void) loginButton:(FBSDKLoginButton *)loginButton didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result error:(NSError *)error { NSLog(@"Login Successfully!!"); NSLog(@"permissions .... %@",[FBSDKAccessToken currentAccessToken].permissions); [self retrieveFeed]; } -(void) loginButtonDidLogOut:(FBSDKLoginButton *)loginButton { } #pragma mark - Receive FB Feed -(void) retrieveFeed { FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/feed" parameters:nil]; FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init]; [connection addRequest:request completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { NSLog(@"%@",result); if(error) NSLog(@"Some error FEED;;;;;; %@",error.localizedDescription); }]; [connection start]; }

On Clicking login Button, I get following permissions screen. Facebook has ignored user_posts permission.

Even if I try to get this permission later after login, Facebook tells me that I have already authorized app to do so, even when there is no such permission granted! The code for getting new permission is:

-(void) checkForFeedPermission { if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"user_posts"]) { NSLog(@"already granted feed access"); [self retrieveFeed]; } else { FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init]; [loginManager logInWithReadPermissions:@[@"user_posts"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { NSLog(@"requesting feed access"); [self retrieveFeed]; }]; } }

I have been banging my head on this issue for three days. Please suggest me where can I be wrong? Thanks.

解决方案

I think that not working for grant user_posts as par Facebook developer documentation for permission you have to submit your Facebook app for review see i attach screenshot that clearly said.

So you have to submit your facebook app for login review might be then you can able to set this permission at loginTime
