如何解決登錄問題，同時在Facebook上分享帖子

Question

我想在Facebook上分享帖子，當我使用iOS 6，但在iOS 5和iOS 5.1時，它提供了登錄問題，當我登錄並去到已經授權頁面，然後按好按鈕，它把我拉回到登錄這樣，再而三地重複這兩個頁面

當我按下行吧還給

case 1: // facebook 
     { 
      if(NSClassFromString(@"SLComposeViewController")) 
      { 
       SLComposeViewController *fbController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; 
       SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){ 

        [fbController dismissViewControllerAnimated:YES completion:nil]; 

        switch(result){ 
         case SLComposeViewControllerResultCancelled: 
         default: 
         { 
          NSLog(@"Cancelled....."); 

         } 
          break; 
         case SLComposeViewControllerResultDone: 
         { 
          ALERT_VIEW(@"Successfully posted to facebook."); 
         } 
          break; 
        }}; 

       [fbController setInitialText:quotesss]; 
       [fbController setCompletionHandler:completionHandler]; 
       [self presentViewController:fbController animated:YES completion:nil]; 
      } 
      else 
      {

          ALERT_VIEW(@"Successfully posted to facebook."); 
          break; 
        } 

        [self dismissViewControllerAnimated:YES completion:nil]; 
       }; 
       DEFacebookComposeViewController *facebookViewComposer = [[DEFacebookComposeViewController alloc] init]; 
       self.modalPresentationStyle = UIModalPresentationCurrentContext; 

       [facebookViewComposer setInitialText:quotesss]; 

       facebookViewComposer.completionHandler = completionHandler; 
       [self presentViewController:facebookViewComposer animated:YES completion:nil]; 
       [facebookViewComposer release]; 
      } 
      break; 
     } 
     case 2: // twitter 
     { 
      NSString *text = [NSString stringWithFormat:@"%@", quotesss ]; 
      if([text length] > 135) 
      { 
       text = [NSString stringWithFormat:@"%@%@", quotesss ,@"..."]; 
       text = [text substringToIndex:135]; 

      } 

      if(NSClassFromString(@"SLComposeViewController")) 
      { 
       SLComposeViewController *twitterController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; 
       SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){ 

        [twitterController dismissViewControllerAnimated:YES completion:nil]; 

        switch(result){

       [twitterController setInitialText:text]; 
       [twitterController setCompletionHandler:completionHandler]; 
       [self presentViewController:twitterController animated:YES completion:nil];

       DETweetComposeViewController *tcvc = [[[DETweetComposeViewController alloc] init] autorelease]; 
       self.modalPresentationStyle = UIModalPresentationCurrentContext; 
       [tcvc setInitialText:quotesss]; 
       tcvc.completionHandler = completionHandler; 

       [self presentViewController:tcvc animated:YES completion:nil]; 

      } 

      break; 
     }

˚F ROM中的代碼，我發現，問題出在iOS 5中的Facebook這個代碼怎麼把不是SLCompose只有Twitter是可用，因此您的Facebook是由DEFaceBook

  DEFacebookComposeViewControllerCompletionHandler completionHandler = ^(DEFacebookComposeViewControllerResult result) { 
       switch (result) { 
        case DEFacebookComposeViewControllerResultCancelled: 
         NSLog(@"Facebook Result: Cancelled"); 
         break; 
        case DEFacebookComposeViewControllerResultDone: 
         ALERT_VIEW(@"Successfully posted to facebook."); 
         break; 
       } 

       [self dismissViewControllerAnimated:YES completion:nil]; 
      }; 
      DEFacebookComposeViewController *facebookViewComposer = [[DEFacebookComposeViewController alloc] init]; 
      self.modalPresentationStyle = UIModalPresentationCurrentContext; 

      [facebookViewComposer setInitialText:quotesss]; 

      facebookViewComposer.completionHandler = completionHandler; 
      [self presentViewController:facebookViewComposer animated:YES completion:nil]; 
      [facebookViewComposer release]; 
     } 

處理，所以還是你的appdelegate並檢查這個方法一個有效的令牌（url其中包含應用程序，令牌格式applicationURLSchema://"token"）檢查它來不來這個方法 如果有必要保持破發點並辦理FBSession類，然後handleOpenURL方法並找到錯誤發生

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication 
annotation:(id)annotation { 

// attempt to extract a token from the url 
return [FBSession.activeSession handleOpenURL:url]; 
}
