    //获取时间戳
    NSTimeInterval time = [[NSDate date] timeIntervalSince1970];
    //转换成标准时间
    NSDate * detaildate=[NSDate dateWithTimeIntervalSince1970:time];
    //实例化一个NSDateFormatter对象
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    //设定时间格式,这里可以设置成自己需要的格式
    NSString *currentDateStr;
    //获取完整的时间
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.TotalTime.text = currentDateStr;
    //获取年份
    [dateFormatter setDateFormat:@"yyyy"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Year.text = currentDateStr;
    //获取月份
    [dateFormatter setDateFormat:@"MM"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Month.text = currentDateStr;
    //获取天
    [dateFormatter setDateFormat:@"dd"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Day.text = currentDateStr;
    //获取24小时制的小时
    [dateFormatter setDateFormat:@"HH"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Hour24.text = currentDateStr;
    //获取12小时制的小时
    [dateFormatter setDateFormat:@"hh"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Hour12.text = currentDateStr;
    //获取分
    [dateFormatter setDateFormat:@"mm"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Minute.text = currentDateStr;
    //获取秒
    [dateFormatter setDateFormat:@"ss"];
    currentDateStr = [dateFormatter stringFromDate: detaildate];
    self.Second.text = currentDateStr;
