我已經構建了一個很好的TableView,其中包含部分,搜索和右側的字母條。如何在包含章節和搜索的UITableView中編寫PrepareForSeque
我測試了它,一切都很順利,直到我注意到「A」之後的任何東西都無法正常工作。我發現原因 - 在我的PrepareForSegue中,我傳遞了在該行發現的對象,但沒有注意到這些部分。
我搜索堆棧溢出,發現了一些像我想要做的事情,但似乎他們編碼在didSelectRowAtIndexPath,沒有準備繼續。我無法獲得任何代碼工作。
我的第一個問題是兩種方法之間的關係是什麼?我正在使用故事板,所以我認爲我應該堅持下去。但是,如何找出哪個員工對象可以通過?
任何幫助將不勝感激。

你會包括你的cellForRowAtIndexPath方法? – Gavin
是的,我將它添加到 –
