'enterButoonOut' - 你拼錯「按鈕」，即這應該是'enterButtonOut'？ – dasblinkenlight

不知道爲什麼它說我把它們全都弄壞了。 – MikeG

「對於enterButoonOut鍵」 - 這就是說你在某處（在故事板或XIB文件中）拼錯了「enterButtonOut」。 –

我通常會得到這樣的錯誤消息時的幾件事情之一發生。

1）我拼錯了segue.identifier的值，因爲我即將跳到另一個模塊（不確定這適用於您的情況，但這是它總是讓我）。 2）如果更改故事板，然後刪除代碼中的值，連接不會在故事板中消除，並且必須手動進入並從故事板中刪除鏈接。要檢查，只需在故事板中的每個元素上單擊鼠標右鍵（或按Ctrl鍵）並記下連接。

我的猜測是，如果你看一下在故事板那個按鈕，您會看到「enterButoonOut」，而不是「enterButtonOut」的

希望這有助於！

故事板中的所有內容都拼寫正確，但是在更改後我確實得到了此錯誤，但我不知道如何解決此問題。 – MikeG

試試這個：將按鈕所在的屏幕調出故事板。點擊選擇按鈕，直到只有按鈕被選中。一旦選定，則可以使用按鈕或按鈕（取決於您的鼠標）。將出現一個菜單，顯示該對象的所有鏈接。我的猜測是列表中會有一個額外的鏈接，其中包含拼寫錯誤的值。在鏈接旁邊，如果您將鼠標懸停在鏈接上，將出現「X」或「*」。點擊該值基本上刪除鏈接。讓我知道這是怎麼回事，因爲我認爲這是你的問題。 –

非常感謝你的工作！ – MikeG

您有拼寫錯誤enterButoonOut，它必須enterButtonOut按你的聲明：

@property (weak, nonatomic) IBOutlet UIButton *enterButtonOut;
