FBWebDialogs presentDialogModallyWithSession打開空白莫代爾

NSString *facebookIDString = [NSString stringWithFormat:@"%lld", facebookID]; 
// Put together the dialog parameters 
NSMutableDictionary *params = 
[NSMutableDictionary dictionaryWithObjectsAndKeys: 
facebookIDString, @"to", 
@"MY APP NAME", @"name", 
@"MY APP CAPTION", @"caption", 
@"MY APP DESCRIPTION", @"description", 
@"http://www.myApp.com", @"link", 
@"https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png", @"picture", 
FACEBOOK_APP_ID, @"app_id", 
nil]; 

// Invoke the dialog 
[FBWebDialogs presentDialogModallyWithSession:[FBSession activeSession] 
              dialog:@"feed" 
             parameters:params 
              handler: 
^(FBWebDialogResult result, NSURL *resultURL, NSError *error) { 
    //My code here 
}];

更新：我只是註釋掉params中的@「圖片」鍵，現在我明白了「塗鴉牆」標頭「好」按鈕，但該模式的內容說：「不能張貼到用戶的牆上「（實際上這是隨機的，有時發生...大多數時候我仍然得到空視圖）FBWebDialogs presentDialogModallyWithSession打開空白莫代爾

如果我刪除@」to「鍵，模式似乎與預期的內容一起工作張貼到我自己的牆上，但我想張貼到朋友的牆上。

我認爲這是一個權限問題，但我打印出來[FBSession activeSession]我有publish_stream

是什麼在你的處理器塊'result'＆'error'的價值？嘗試：'NSLog（@「result：％d，error：％@」，result，[errors localizedDescription]）;'在你的'handler'塊 –

處理程序塊不會被調用，直到我通過點擊'X '在右上角。當我這樣做時，error = nil，resultURL = nil，result = 1（或FBWebDialogResultDialogNotCompleted） –
