Facebook SDK 4.x权限问题iOS [英] Facebook SDK 4.x Permission issue iOS

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
