我在iOS應用程序（ARC，在iOS 5上運行）中使用Facebook連接。它在模擬器和設備上都能正常工作，但自從今天上午它已經停止在設備上工作，它仍然可以在模擬器上工作。在設備上，我得到了名爲fbDinNotLogin的方法。iOS Facebook SDK連接在iDevice上失敗
現在，我知道差異是模擬器使用手機Facebook和我的應用程序使用本機iOS的Facebook應用程序，我也知道你可以調整facebook.m文件強制應用程序在別處做登錄，但我不'不想這樣做。
從昨天加載我以前的版本（一切工作正常）也給了我相同的結果。所以昨天運行的代碼今天不運行。任何想法爲什麼會發生？下面是我的代理.m文件：
[EIDT]我從原生Facebook應用程序獲得各種不同的行爲。有時它會打開Facebook應用程序，並停留在那裏不會回到我的應用程序。有時它也會快速返回到我的應用程序，而不允許Facebook應用程序詢問我的許可。我很困惑。 [/編輯]
