{

  // 异常的堆栈信息

  // 出现异常的原因

  // 实例化NSDateFormatter

  NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

  // 设置日期格式

  [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

  // 获取当前日期

  NSDate *currentDate = [NSDate date];

  NSString *currentDateString = [formatter stringFromDate:currentDate];

  NSTimeInterval time = [currentDate timeIntervalSinceDate:[PCUtil getAppLauchTime]];

    NSString* useTime=[NSString stringWithFormat:@"%d",(int)time];

  }

//准备要存入的字典

  NSDictionary *errDic = @{

                             @"flag":flag,

                            @"exceptionInfo":exceptionInfo

                            };

  //将字典存入指定的本地文件

}

使用在appDelegate里面

//注册消息处理函数的处理方法

    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);

    //上次异常闪退信息上传

    double seconds = 3.0;

    dispatch_time_t postTime = dispatch_time(DISPATCH_TIME_NOW, seconds * NSEC_PER_SEC);

    dispatch_after(postTime, dispatch_get_main_queue(), ^(void){

//上传服务端

    });
