在我们开发的app中, 不可避免的, 有时候用户使用软件会崩溃. 我们就需要捕获异常, 可以在入口类中加入相应的代码, 可以在每次用户打开程序的时候, 检查一下沙盒中是否有崩溃日志, 如果有, 可以发送给服务器, 方便改进软件.

{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
ExceptionHandler 捕获异常的宏定义
// 这里反馈给服务器
