我開發的Facebook登錄的應用程序，我跟着Facebook開發人員頁的所有指令類型NSException的未捕獲的異常終止Facebook登錄：在IOS迅速
所有工作fine.But同時運行的Facebook登錄的應用程序崩潰，顯示
class appdelegate uiresponder uiapplicationdelegate{
thread 1 signal sigabrt on this line in delegate
這裏有更詳細的錯誤：

我搜索更多關於這一點，但他們都表示，檢查連接上的UIView，但我有視圖控制器上的一個小視圖，而且正確連接
我的視圖控制器是

if(FBSDKAccessToken.currentAccessToken()==nil){
print("User not logged in")
} else {
print("Logged in")
}
login.delegate = self
login.readPermissions = ["public_profile","email","user_friends"]
