的Facebook牆上張貼剛過Facebook的註冊iOS-的Facebook SDK 3.2

Question

的Facebook SDK 3.2

我只需要登錄與功能NEW後張貼在Facebook的牆後。

這裏是我使用的代碼：

這裏我有一個打開的會話的Facebook：

- (IBAction)FBSignup:(id)sender { 
    [[AppDelegate sharedObject] openSession:^(FBSession *session, FBSessionState state, NSError *error) { 
     [self sessionStateChanged:session state:state error:error]; 
    }]; 
} 

狀態改變，我填充數據與[自populateUserDetails]，然後試圖張貼在Facebook牆上以及[self postOnFB]，但沒有張貼在Facebook牆上。

- (void)sessionStateChanged:(FBSession *)session 
         state:(FBSessionState) state 
         error:(NSError *)error 
{ 
    switch (state) { 
     case FBSessionStateOpen: 

      [self populateUserDetails]; 
      [self postOnFB]; 
      break; 

     case FBSessionStateClosed: 
     case FBSessionStateClosedLoginFailed: 
      [FBSession.activeSession closeAndClearTokenInformation]; 
      break; 
     default: 
      break; 
    } 

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

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

在這裏，我彈出與facebook用戶對象，我需要的數據。

- (void)populateUserDetails 
{ 
    if (FBSession.activeSession.isOpen) { 

     [[FBRequest requestForMe] startWithCompletionHandler: 
     ^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) { 

      if (!error) { 
       /////////////////////////////// 
       // Populating Data Where Needed 
       /////////////////////////////// 


       // [self postOnFB]; 
      } 
     }]; 
    } 
} 

在這裏，我嘗試張貼的牆後與[自postOnFB]提示錯誤：

Terminating app due to uncaught exception 'com.facebook.sdk:InvalidOperationException', reason: 'FBSession: It is not valid to reauthorize while a previous reauthorize call has not yet completed.

我在這裏張貼在牆上。對於Facebook壁交

- (void)postOnFB{ 

    // Ask for publish_actions permissions in context 
    if ([FBSession.activeSession.permissions 
     indexOfObject:@"publish_actions"] == NSNotFound) { 
     // No permissions found in session, ask for it 
     [FBSession.activeSession requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] 
               defaultAudience:FBSessionDefaultAudienceFriends 
              completionHandler:^(FBSession *session, NSError *error) { 
               if (!error) { 
                [self fbPostSettings]; 
               } 
              }]; 
    } else { 
     // If permissions present, publish the story 
     [self fbPostSettings]; 
    } 
} 

設置參數：

- (void)fbPostSettings{ 

NSDictionary * facebookParams = [[NSMutableDictionary alloc] initWithObjectsAndKeys: 
    kFacebookPostLink,        @"link", 
    kFacebookPostImage,       @"picture", 
    kFacebookPostName,        @"name", 
    kFacebookPostCaption,       @"caption", 
    kFacebookPostDescription,      @"description", 
    nil]; 

    [FBRequestConnection startWithGraphPath:@"me/feed" 
           parameters:facebookParams 
           HTTPMethod:@"POST" 
          completionHandler:^(FBRequestConnection *connection, 
               id result, 
               NSError *error) { 
           NSString *alertText; 
           if (error) { 
            alertText = [NSString stringWithFormat: 
               @"error: domain = %@, code = %d", 
               error.domain, error.code]; 
           } else { 
            alertText = [NSString stringWithFormat: 
               @"Posted action, id: %@", 
               [result objectForKey:@"id"]]; 
           } 
           NSLog(@"%@",alertText); 
          }]; 
} 

- (void)sessionStateChanged:(NSNotification*)notification { 
    [self populateUserDetails]; 
} 

如果我打電話postOnFB一些按鈕操作選擇器（通過Facebook用戶對象數據羣結束後），它貼在所述壁細。但我需要發佈它後，我得到startWithCompletionHandler： ^（FBRequestConnection *連接，NSDictionary *用戶，NSError *錯誤）方法的用戶對象。

請幫忙。謝謝大家:)

不是打開會話，然後請求發佈權限，直接要求發佈的權限打開該會話

[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObjects:@"publish_stream", 
                nil] defaultAudience:FBSessionDefaultAudienceEveryone allowLoginUI:YES completionHandler:^(FBSession *session, 
    FBSessionState state, NSError *error) { 
if (FBSession.activeSession.isOpen && !error) { 
    [self fbPostSettings]; 
}];
