你可能会释​​放一个对象太多次了（例如，调用alloc一次并释放两次）。要找出答案，请查看此问题中的技巧：如何找到malloc的原因double free错误？

You are probably releasing an object too many times (for example, calling alloc once and release twice). To find out where, take a look at the techniques in this question: How to find the cause of a malloc "double free" error?

我个人喜欢 NSZombieEnabled 方法。

另一个提示是，在释放它们之后将变量设置为nil。

Another tip, is to set your variables to nil after you release them.

例如： [bla release]; bla = nil;

这确保您在发布 nil $ c $后不会意外释放它们两次c>什么都不做。

This makes sure you will not accidentally release them twice since releasing nil does nothing.
