iphone - 输入撇号(')时，UITextField使应用程序崩溃

Question

在文本字段中输入'(撇号)时，我的应用程序崩溃了。任何人都可以告诉问题的解决方案。下面是它崩溃的地方

hotelTextfield.text =  [hotelList objectAtIndex:indexPath.row];

我在文本字段中输入了其他字符串，但这些字符串没有引起任何问题。但是每当我输入一些'，它就会崩溃。
请找到崩溃的堆栈回溯

Program received signal:  “EXC_BAD_ACCESS”.

好，问题解决了。这是由于SQLite。 Sqlite无法处理撇号(')。通过在发送到SQLite之前添加一个额外的'来解决它。
