FBDialogs presentShareDialogWithParams回調處理程序永遠不會被調用

Question

我正在使用FBDialogs在Facebook上共享。

Facebook的共享工作正常，但處理程序不會被調用（我把一個斷點在第一行）

我的SDK通過的CocoaPods安裝

pod 'Facebook-iOS-SDK',   '3.9.0' 

這裏的代碼，相當多的例如在Facebook的開發頁面。我正在用ios7測試IPod。

// If the Facebook app is installed and we can present the share dialog 
if ([FBDialogs canPresentShareDialogWithParams:params]) { 
    // Present the share dialog 

    [FBDialogs presentShareDialogWithParams:params 
           clientState:nil 
            handler:^(FBAppCall *call, NSDictionary *results, NSError *error) { 
             //never gets here 
             if(error) { 
              UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" 
                          message:[NSString stringWithFormat: @"O comparilhando não foi bem sucedido. %@",error.description] 
                          delegate:nil 
                        cancelButtonTitle:@"OK" 
                        otherButtonTitles:nil]; 
              [alert show]; 

             } else { 
              UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Sucesso" 
                          message:@"O compartilhando foi bem sucedido" 
                          delegate:nil 
                        cancelButtonTitle:@"OK" 
                        otherButtonTitles:nil]; 
              [alert show]; 

             }}]; 

SOLUTION：

我的老闆到底琢磨出來。 我在AppDelegate中缺少這個方法。沒有它，Facebook的不能傳遞數據回我的應用程序

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

BOOL urlWasHandled = [FBAppCall handleOpenURL:url 
          sourceApplication:sourceApplication 
           fallbackHandler:^(FBAppCall *call) { 
            // incoming link processing goes here 
           }]; 

    return urlWasHandled; 
} 

Answer 1

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


    if ([[[[NSString stringWithFormat:@"%@",url] componentsSeparatedByString:@":"] objectAtIndex:0]isEqualToString:@"your FB ID"]) { 

     return [FBSession.activeSession handleOpenURL:url]; 

    } 

可能是這樣的幫助你。
