wxhandler's Introduction

开发iOS应用,解决Crash问题始终是一个难题。Crash分为两种,一种是由EXC_BAD_ACCESS引起的,原因是访问了不属于本进程的内存地址,有可能是访问已被释放的内存;另一种是未被捕获的Objective-C异常(NSException),导致程序向自身发送了SIGABRT信号而崩溃。其实对于未捕获的Objective-C异常,我们是有办法将它记录下来的,如果日志记录得当,能够解决绝大部分崩溃的问题。这里对于UI线程与后台线程分别说明。

网上的捕获异常的方法都大同小异,都是处理处理signal信号。这里我把捕获的异常保存到缓存目录上,然后你可以通过邮件或者网络接口把自己发给自己或者公司,便于自己分析和在下个版本上进行修复工作。
