iphone 异常捕获处理

 1 void UncaughtExceptionHandler(NSException *exception) {
 2     NSArray *arr = [exception callStackSymbols];
 3     NSString *reason = [exception reason];
 4     NSString *name = [exception name];
 5     NSString *urlStr = [NSString stringWithFormat:@"mailto://XXX@XXX.com?subject=bug报告&body=感谢您的配合!<br><br><br>"
 6                         "错误详情:<br>%@<br>--------------------------<br>%@<br>---------------------<br>%@",
 7                         name,
 8                         reason,
 9                         [arr componentsJoinedByString:@"<br>"]];
10     NSURL *url = [NSURL URLWithString:[urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
11     [[UIApplication sharedApplication] openURL:url];
12 }

然后在程序启动中加入异常捕获回调

1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
2 {
3     // Override point for customization after application launch.
4     NSSetUncaughtExceptionHandler (&UncaughtExceptionHandler);
5     return YES;
6 }
