程序异常后通过邮件发送

void UncaughtExceptionHandler(NSException *exception) {
NSArray *arr = [exception callStackSymbols];
NSString *reason = [exception reason];
NSString *name = [exception name];
NSString *urlStr = [NSString stringWithFormat:@"mailto://[e-mail]?subject=bug报告&body=感谢您的配合!<br><br><br>"
"错误详情:<br>%@<br>--------------------------<br>%@<br>---------------------<br>%@", 
name,reason,[arr componentsJoinedByString:@"<br>"]];
NSURL *url = [NSURL URLWithString:[urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[[UIApplication sharedApplication] openURL:url];
}

    然后在delegate文件里面- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions函数里面添加NSSetUncaughtExceptionHandler (&UncaughtExceptionHandler);

    这样就大功告成了。
