什麼即時試圖做的是打印（輸出：西澳大利亞州）如何使用變量具有代碼塊外值
self.stateName = state["ProvinceStateName"]
要
detailAddressArr = ["\(userData!["AddressLine1"] as! String)", "\(userData!["AddressLine2"] as! String)", "\(userData!["City"] as! String)", "\(userData!["PostalCode"] as! String)", self.stateName, "\(userData!["CountryCode"] as! String)"]
但在運行時，它返回任何結果。
這裏是我的代碼

建議1： 嘗試打印detailAddressArr時發生新錯誤（索引超出範圍）。 建議2： statename return nil –
