iPhone 4.0 NSDateFormatter 崩溃
我需要使用我的个人数据格式将 NSDate 转换为字符串...... 问题是模拟器（4.01）上的这段代码崩溃了...... 有时代码被“冻结”，有时给出 BAD_ACCESS... 这是代码：
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
I need to convert a NSDate to a string using my personal data format...
The problem is that this code on the simulator (4.01) crashes...
sometimes the code is "freezed", sometimes give the BAD_ACCESS...
here is the code:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];

这可能不是这段代码，而是您的应用程序中的其他问题。我写了一篇博客，介绍了查找错误的各种方法

问题是您在进行错误的内存访问时获得 EXC_BAD_ACCESS，而不是在损坏时获得 EXC_BAD_ACCESS堆或引起了根本问题。
如果 alloc 崩溃，则很有可能您的堆已损坏，并且损坏发生在该代码之前。
It's likely not this code, but some other problem in your app. I wrote a blog that goes through the various ways to find the bug

The issue is you get EXC_BAD_ACCESS at the point that a bad memory access is made, not at the point that corrupted the heap or caused the underlying problem.
If alloc is crashing, it's a good bet that your heap is corrupt, and that the corruption happened earlier than this code.
