EXC_BAD_ACCESS當我滾動我的視圖

-1

我有兩個視圖：第一個是UITableView以普通樣式（以編程方式創建）;第二個是UIScrollView，其中包含圖像和分組樣式的UITableView（也是以編程方式創建的）。EXC_BAD_ACCESS當我滾動我的視圖

當我從firstView - > secondView導航一切正常。但是，如果我回到firstView，然後嘗試第二次導航firstView - > secondView，則會出現EXC_BAD_ACCESS錯誤。

UPDATE

這是UITableView代表在secondView的代碼：

-

    switch (section) { 
     case 0: 

     //header - breve descrizione 
     return 2; 

     break; 
    case 1: //mappa 

     //header - mappa statica (immagine) - footer (indirizzo) 
     return 3; 

     break; 
    case 2: //review 

     //header - prima review 
     return 2; 

     break; 
    default: 
     return 0; 

     break; 


} 

}

    switch (indexPath.section) {

達尼請搜索EXC_BAD_ACCESS ..或者直接點擊任何在右列中的相關鏈接。有很多方法可以調試（提示：殭屍）。我相信你將能夠自己解決這個問題。如果沒有代碼，沒有人能夠提供幫助。 – Joe 2012-02-10 18:20:23

我們需要查看您的代碼，您是否還在使用ARC？ – GregularExpressions 2012-02-10 18:20:34

您是否將版本發送給所有分配的對象？看來你試圖訪問釋放對象.. – LightNight 2012-02-10 18:29:15

的EXC_BAD_ACCESS不是由一個視圖到下一的進展引起的。相反，它將成爲那些觀點的屬性，或者是創造和釋放（或不是）視角對象本身的責任。

您的第一步是運行分析儀。然後，如果您已經修復了所有這些問題，並且仍然存在問題，請開始在樂器中運行「泄漏」工具。

有關解決EXC_BAD_ACCESS問題，有什麼原因導致這些錯誤，並步步爲如何解決逐步說明優秀的鏈接以及更多的細節，看看這些問題的答案：

在你的情況，我會專門看你如何創建secondView，和你firstView做什麼，當你回到secondView。

爲什麼編輯這個錯誤信息是錯誤的？ – Diziet 2012-02-14 15:19:35

dunno。這是一個常見的錯誤。我剛修好了。 – 2012-02-14 15:46:09

我剛剛花了一個星期的時間跟蹤了一個大型應用程序中的EXC_BAD_ACCESS問題，該應用程序在將其轉換爲ARC之前工作正常。我會在「switch」結構的右括號上得到EXC_BAD_ACCESS。然而NSZombieEnabled和各種樂器設置不會爲我檢測到任何東西。

這是什麼修正它把案件的捲毛放在了不同的地方。我這樣做是爲他們每個人，雖然也許它是隻有一些關鍵的，即

前：

case ...: 
stmt; 
stmt; 
break;

後：

case ...:{ 
stmt; 
stmt; 
}break;

這兩個地方的固定內的大問題應用程序爲我。我知道我讀了關於ARC和switch/case的一些東西（也許有人可以添加一個鏈接），但我不明白爲什麼會發生這種情況，以及爲什麼這個修復工作。也許有人可以解釋。（稍後：在閱讀openradar中的以下參考資料之後，這一切都是有道理的 - 在case語句之間生成的「清除代碼」中存在錯誤---生成了一個假「釋放」並且很快會導致EXC_BAD_ACCESS。）

我也發現了這一點，這可能與：http://openradar.appspot.com/11329693
