Facebook Sdk为ios发布-dark屏幕 [英] Facebook Sdk for ios publish -dark screen

问题描述

我正在Facebook上分享。
但是每次请求发布权限时，都会指示一个屏幕
您已经授权给AppName。当我点击确定。它带我到空白屏幕。

这是我的流程。
1.登录到Facebook
2.请求发布权限。
3.发布到Facebook墙。

  [FBSession.activeSession requestNewPublishPermissions：[NSArray arrayWithObject：@publish_actions] 
 defaultAudience：FBSessionDefaultAudienceFriends 
 completionHandler：^（FBSession * session，NSError * error）{
 if（！error）{
 //现在有权限
 [self publishStory]; 
} else {
 // Facebook SDK *错误处理* 
 //如果操作未被用户取消
 if（error.fberrorCategory！= FBErrorCategoryUserCancelled）{
 [self presentAlertForError：error]; 
} 
} 
}]; 
  

解决方案

你可以这样做，

在打开会话时指定发布帖子的权限

  NSArray * permissions = [[NSArray alloc] initWithObjects：@publish_actions，@publish_stream，nil]; //权限
返回[FBSession openActiveSessionWithPermissions：permission allowLoginUI：allowLoginUI completionHandler：^（FBSession * session，FBSessionState state，NSError * error）
  

每当你想发布，都这样做

  NSMutableDictionary * params = [[NSMutableDictionary alloc] initWithObjectsAndKeys：TextView.text，@ ，零]; //设置格式
 if（[FBSession.activeSession.permissions indexOfObject：@publish_actions]！= NSNotFound）
 {
 [FBRequestConnection startWithGraphPath：@me / feedparameters：params HTTPMethod：@POSTcompletionHandler：^（FBRequestConnection * connection，id result，NSError * error）
 {
 NSString * alertText; 
 if（error）
 {
 //如果发生错误
 
} 
 else 
 {
 // successfull 
} 
 
}]; 
 
} 
 
} 
  

I am trying to share on Facebook. But every time it request permission to publish, it will direct a screen "You have authorized to the "AppName"". When I click on OK. It brought me to blank screen.

Here is my flow. 1. Login to Facebook 2. Request for publish permission. 3. Publish to Facebook wall.

 [FBSession.activeSession requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
                                      defaultAudience:FBSessionDefaultAudienceFriends
                                    completionHandler:^(FBSession *session, NSError *error) {
                                        if (!error) {
                                            // Now have the permission
                                            [self publishStory];
                                        } else {
                                            // Facebook SDK * error handling *
                                            // if the operation is not user cancelled
                                            if (error.fberrorCategory != FBErrorCategoryUserCancelled) {
                                                [self presentAlertForError:error];
                                            }
                                        }
                                    }];

解决方案

You can do like this,

while opening the session specify permission to publish post

   NSArray  *permissions = [[NSArray alloc] initWithObjects:@"publish_actions",@"publish_stream",nil]; //permissions
  return [FBSession openActiveSessionWithPermissions:permissions allowLoginUI:allowLoginUI completionHandler:^(FBSession *session,FBSessionState state,NSError *error)

and whenever you want to publish, do like this

  NSMutableDictionary *params = [[NSMutableDictionary alloc]initWithObjectsAndKeys:TextView.text, @"message",nil]; // set the formats
if([FBSession.activeSession.permissions indexOfObject:@"publish_actions"] != NSNotFound)
{
    [FBRequestConnection startWithGraphPath:@"me/feed" parameters:params HTTPMethod:@"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
     {
         NSString *alertText;
         if(error)
         {
              //if error occurred

         }
         else
         {
             //successfull
         }

     }];

    }

 }
