如何將數組添加到TableViewController？

Question

當我在互聯網上衝浪時，我發現了很多示例如何在TableViewController中加載數組，但是沒有一個能夠幫助我！

難道你不能幫我找到我的代碼有什麼問題嗎？

謝謝！

Answer 1

以及1）numberOfSections爲0。看到的東西應該是一個IIRC 認爲多數民衆贊成，但還沒有雙重檢查

Answer 2

假設你data陣列正確建起來了，你的錯誤在你numberOfSections方法。目前，它返回0，它告訴UITableView目前沒有要顯示的部分......曾經。

您可以選擇return 1;那裏或完全刪除整個方法。從UITableViewController繼承的默認實現默認也返回1。

我的建議是刪除該方法，因爲這樣可以保持自己的代碼更清潔。你可以隨時在後續階段實施，當你真的需要它時。
