Implementation Code:

#pragma mark - timeClick- (void)timeClick:(UIButton *)btn{    long testTime = [ _timeTextFiled.text intValue];//定义一个长整形变量    NSNumber *nsTime = [NSNumber numberWithLong:testTime];//将基本数据类型转换为NSNumber数据类型    int hour = [nsTime intValue] / 3600;    int minute = ([nsTime intValue] % 3600) / 60;    int second = [nsTime intValue] % 60;    if (hour < 10){        if (minute < 10 && second >= 10){            _timeLable.text = [NSString stringWithFormat:@"0%d:0%d:%d", hour, minute, second];        }else if (minute < 10 && second < 10){            _timeLable.text = [NSString stringWithFormat:@"0%d:0%d:0%d", hour, minute, second];        }else if (minute >= 10 && second < 10) {            _timeLable.text = [NSString stringWithFormat:@"0%d:%d:0%d", hour, minute, second];        }else if (minute >= 10 && second >= 10){            _timeLable.text = [NSString stringWithFormat:@"0%d:%d:%d", hour, minute, second];        }    }else {        if (minute < 10 && second >= 10){            _timeLable.text = [NSString stringWithFormat:@"%d:0%d:%d", hour, minute, second];        }else if (minute < 10 && second < 10){            _timeLable.text = [NSString stringWithFormat:@"%d:0%d:0%d", hour, minute, second];        }else if (minute >= 10 && second < 10) {            _timeLable.text = [NSString stringWithFormat:@"%d:%d:0%d", hour, minute, second];        }else if (minute >= 10 && second >= 10){            _timeLable.text = [NSString stringWithFormat:@"%d:%d:%d", hour, minute, second];        }    }    //隐藏键盘    [_timeTextFiled resignFirstResponder];}
