NSUnknownKeyException ios Objective C

-1

我爲我的ios應用程序創建了一個幻燈片抽屜..幻燈片抽屜工作完美...我有幾個按鈕和幻燈片抽屜中的文本框...問題是每當我嘗試添加引用在幻燈片抽屜中的按鈕/文本框，我得到NSUnknownKeyException ...我不知道如何解決這個問題，因爲我是非常新的IO ...包括下面的代碼...NSUnknownKeyException ios Objective C

EDIT

異常是在main.m文件

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

你得到的例外是什麼？另外，在Xcode中添加一個異常斷點，這樣你就可以看到哪一行導致異常被拋出。 –

請檢查修改過的問題... –

您正在使用xib，對嗎？ – Miknash

這有兩個可能的原因：

容易，你有連接，刪除元素，但鏈接的出口和代碼之間保持，現在指向空。您可以在界面構建器右側的最後一個選項卡中查看這一個。

另一個：你已經連接你的插座文件所有者，而不是班級。取下你的插座並將它們連接到班級。當你連接你的插座（從代碼到元素，你將有空圈），你將得到選擇的彈出窗口：文件所有者 - 類。

編輯：

按x鍵取出插座，然後再次從代碼中重新連接。當您刪除這些插座時，您將在.h類中有空圈並再次重新連接到SlideDrawer。

你能爲我提供第二個解決方案的截圖嗎？ –

好吧，它很難做到只有圖像，但它很容易遵循以下步驟：打開SlideDrawer.xib - >去商店，按實心圓去刪除網點 - >打開SlideDrawer.h - >你將有空的圓圈現在 - >將它們連接到相應的元素 - >選擇SlideDrawer而不是文件所有者 – Miknash

很抱歉說這個..但是我無法在SlideDrawer.h中找到任何空的電路...... :( –

解

終止

STEP 1:Go XIB or if use STORYBOARD go STORYBOARD 
STEP 2:Click View Controller 
STEP 3:Again Give connection properly(Fill the circle) 
STEP 4:Also check whether it is for button action or outlet property

非常重要：右鍵點擊「連接檢查」（右上箭頭）文件的所有者（黃色）和點擊，查看所有網點一次。找出指示缺少插座的！s。取消。現在，它的工作。
