快速核心數據陣列

嗨，大家好，我有一個問題。在許多視頻之後，我不明白如何使用Core Data來存儲陣列。快速核心數據陣列

我有一個應用程序，在一個視圖中，我推出了16 TextLabel。我需要使用Core Data來存儲字符串列表。當我啓動程序時，我需要從數組中加載數據。但有時我需要用文本字段中的文本更改一個TextLabel的數據，然後重新加載所有16個文本標籤。

有人可以幫助我的代碼？

對不起，但我還沒有理解它是如何工作的。

我已經創建了具有核心數據的項目。謝謝所有

我們希望能幫助您解決代碼問題，但請分享您已擁有的代碼，以便我們可以從某處開始。 –

的第一個建議：用tag s的標籤替換所有的網點。這將產生更少的代碼，這將更具可讀性。您可以使用方便的循環來填寫標籤。例如，您的「主要」標籤可能具有標籤10-17，
您的「次要」標籤可能具有標籤20-27。

爲了得到一個特定的標籤，只需要使用

let label = view.viewWithTag(20) as! UILabel

其次，用於存儲16個字符串數組，使用NSUserDefaults這是更簡單，專爲這種數據量和類型。

NSUserDefaults.standardUserDefaults().setObject(array, forKey: "myArray")

有我的代碼。在這個視圖中，我想使用數組設置所有16個文本標籤。當我按下其中一個文本標籤下的按鈕時，我需要更改granigliatoreTF中的字符串數據，然後重新加載所有16個文本標籤。我只實現了一個啓動按鈕。感謝所有
