这里有一个奇怪的......

我有一个应用程序多年来运行稳定，最近我做了一点补充。我在几台设备（iPhone 4、3GS）上测试了该应用程序，并在调试 AdHoc 安装模式下进行了测试。该应用程序完美地通过了 Apple 的审核流程。但是现在当人们从应用商店加载更新时，应用在按下按钮时会随机崩溃。崩溃日志不好，因为在符号化之后，它们显示崩溃发生在 main:12....

该应用程序自古以来就是为 iOS 4.1 构建的，从来没有出现过问题。

不用说，导致崩溃的键之前已经工作过，与我放入应用程序的新功能无关:-(

无论如何，这里是日志之一。有任何想法吗？

wowzers....我终于找到了问题，我迫不及待地想分享。

“Guard Malloc”和“Enable Guard Edges”终于帮我找到了错误。使用 calloc 分配了两个 Float32 数组，但是访问它们并将 Float32 写入其中的索引太大了 1（我们之前没有听说过吗？！？）。

启用 Guard Malloc 后，调试器在发生错误访问的源代码点处停止，但原因不太明显。对 calloc 感到厌烦（实际上从我早期的 C 编码时代开始就一直如此）我将数组更改为 NSMUtableArrays 并猜猜看，Guard Malloc 再次停在同一行代码处（这次用 NSMutableArray 替换 *Float32 指针） ，但因为它是Objective-C，它还告诉我索引超出范围并给了我一个堆栈跟踪。

通过为数组分配正确的大小，修复当然很容易，但让我担心的是这个错误的代码自 2008 年以来就在应用程序中，它从未引起任何问题！刚才我在 App 内存中添加了一些东西，一定是转移到了“黑暗面”。

所以....你有它，当你在你的主目录中得到一个 EXEC_BAD_ACCESS 时，注意 calloc / malloc / free 并检查，仔细检查并重新检查你的索引。

顺便说一句，在 Xcode 4 中，为 Guard Malloc 等设置这些标志是通过“编辑方案”完成的

主要的 EXC_BAD_ACCESS。这听起来像是您在某处过度释放了一个对象，当它返回主运行循环并且默认NSAutoreleasePool排水管时，它正在访问一个已经释放的对象以自动释放它。

进行调试的一种好方法是将可疑函数包装为：

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// the rest of the function
[pool release]; // drains the pool automatically
return; // you need to add the above line before each time you would return

然后希望您会看到过度释放对象的功能。如果是正在释放的自定义对象导致崩溃，则可能是autorelease您没有retain或您alloc自己的该对象的成员变量。这也可能是@property (assign)您使用的任何 's 的情况，如果您曾经使用过release它们而没有retain编辑过它们。
