前言：前段时间请假去参加了一个联通举办的乒乓球比赛，虽然没有拿到第一名，但是我也不是最后一名（偷笑）。在比赛中看到裁判员还是用原始的记录方式-纸质来记录分数（虽然不能全部替代纸质），感觉是不是能用手机（这里用手机代表，不是App，为了方便使用后来我也开发了小程序版来记分，实现基本的记分功能，于是它诞生了-比赛记分牌。废话不多说，先看下App的效果图：

待开发功能

计时功能
一局比赛结束换位功能

具体功能实现：

1.页面布局：小比分使用UIPageViewController，可以实现翻页效果和自带的点击效果；使用Masonry和frame混合布局
2.数据存储：fmdb使用

主要详细功能实现：

1.分数视图封装：包括上面的小比分，加减和重置按钮，UIPageViewController的使用；

• 1-1.初始化 底部添加一个背景视图 RBScoreView类

 CGFloat width = kSCREENW/2 - 2*KWidth(20);
    self.pageBgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, width)];
    [self addSubview:self.pageBgView];
    
    self.pageVC = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl navigationOrientation:UIPageViewControllerNavigationOrientationVertical options:nil];
    self.pageVC.view.frame = self.pageBgView.bounds;
    // 设置当前显示的控制器
    [self.pageVC setViewControllers:@[self.dataArray[0]] direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
    self.pageVC.delegate = self;
    self.pageVC.dataSource = self;
    [self.pageBgView addSubview:self.pageVC.view];
    [self.parentVC addChildViewController:self.pageVC];

• 1-2.仿UITableView代理方法 自定义方法 通过索引获取当前的控制器

- (RBPageChildrenVC *)viewControllerAtIndex:(NSUInteger)index {
    // Return the data view controller for the given index.
    if (([self.dataArray count] == 0) || (index >= [self.dataArray count])) {
        return nil;
    }
    
    RBPageChildrenVC *chiledVC = self.dataArray[index];
    
    return chiledVC;
}

• 1-3.仿UITableView代理方法 自定义方法 通过当前的控制器获取索引，number是自控制器的一个属性

- (NSUInteger)indexOfViewController:(RBPageChildrenVC *)viewController {
    return viewController.number.integerValue;
}

• 1-4.UIPageViewController代理方法

// 向前翻页展示的ViewController
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {
    NSInteger index = [self indexOfViewController:(RBPageChildrenVC *)viewController];
    
    if ((index == 0) || (index == NSNotFound)) {
        return nil;
    }
    
    index--;
    self.currentIndex = index;
    return [self viewControllerAtIndex:index];
}

// 向后翻页展示的ViewController
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {
    NSUInteger index = [self indexOfViewController:(RBPageChildrenVC *)viewController];
    if (index == NSNotFound) {
        return nil;
    }
    
    index++;
    self.currentIndex = index;
    if (index == [self.dataArray count]) {
        return nil;
    }
    return [self viewControllerAtIndex:index];
}

• 1-5.初始化数据源

- (NSMutableArray *)leftArray {
    if (_leftArray == nil) {
        _leftArray = [NSMutableArray arrayWithCapacity:0];
        
        for (int i = 0; i <= MAX_COUNT; i++) {
            RBPageChildrenVC *childrenVC = [[RBPageChildrenVC alloc] init];
            childrenVC.isRed = YES;
            childrenVC.number = [NSString stringWithFormat:@"%d", i];
            [_leftArray addObject:childrenVC];
        }
    }
    
    return _leftArray;
}

• 1-6.初始化视图

    self.leftScoreView = [[RBScoreView alloc] initWithFrame:CGRectMake(0, 0, width, width + KHeight(10+2*44)) parentVC:self dataArray:self.leftArray];
    self.leftScoreView.backgroundColor = RBRedColor;
    [self.leftBgView addSubview:self.leftScoreView];
//    self.leftScoreView.buttonClickAnimated = YES;

    [self.leftScoreView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.equalTo(self.leftBgView).offset(0);
        make.size.mas_equalTo(CGSizeMake(width, width + KHeight(10+2*44)));
        make.top.equalTo(self.leftBgView.mas_centerY).offset(0);
    }];

到这里首页基本的视图就OK了，其他的都是很简单控件的使用了。

首页最终效果图

2.比赛记录数据存储：fmdb数据库封装，小比分的存储

• 2-1.SQLite数据库 基本数据类型

• 2-2.创建表 注意关闭使用FMDatabase后 记得关闭

    NSString *path = [NSHomeDirectory() stringByAppendingString:@"/Documents/Score.db"];
    NSLog(@"------path:%@", path);
    fmDatabase = [FMDatabase databaseWithPath:path];
    BOOL isOpen = [fmDatabase open];
    if (isOpen) {
        NSLog(@"数据库打开成功!");
    } else {
        NSLog(@"数据库打开失败!");
    }
    
    NSString *sql = @"create table if not exists MyScore(id integer primary key autoincrement, date text, content text, redname text, bluename text, redscore integer, bluescore integer, gametype integer)";
    if ([fmDatabase executeUpdate:sql]) {
        NSLog(@"表创建成功!");
        [fmDatabase close];
    } else {
        NSLog(@"表创建失败!");
    }

• 2-3.插入数据 int或NSInteger类型插入时加@(int/NSInteger)，注意插入的是对象

if ([fmDatabase executeUpdate:sql, score.date, score.content, score.redName, score.blueName, @(score.redScore), @(score.blueScore), @(score.blueScore), @(score.gameType)]) {
        NSLog(@"数据插入成功!");
        
        [fmDatabase close];
    } else {
        NSLog(@"数据插入失败!");
        NSLog(@"error = %@", [fmDatabase lastErrorMessage]);
    }

• 2-4 查询比赛结果

    BOOL isOpen = [fmDatabase open];
    if (isOpen) {
        NSLog(@"数据库打开成功!");
    } else {
        NSLog(@"数据库打开失败!");
    }
    
    NSString *sql = @"select * from MyScore";
    FMResultSet *set = [fmDatabase executeQuery:sql];
    NSMutableArray *array = [[NSMutableArray alloc] init];
    
    while ([set next]) {
        RBScoreModel *scoreModel = [[RBScoreModel alloc] init];
        scoreModel.date = [set stringForColumn:@"date"];
        scoreModel.content = [set stringForColumn:@"content"];
        scoreModel.scoreId = [set intForColumn:@"id"];
        scoreModel.redName = [set stringForColumn:@"redname"];
        scoreModel.redScore = [set intForColumn:@"redscore"];
        scoreModel.blueName = [set stringForColumn:@"bluename"];
        scoreModel.blueScore = [set intForColumn:@"bluescore"];
        scoreModel.gameType = [set intForColumn:@"gametype"];

        [array addObject:scoreModel];
    }
    
    [fmDatabase close];
    return array;

• 2-5.删除表 删除成功后重新创建table 防止新增字段

- (BOOL)deleteTable {
    NSString *path = [NSHomeDirectory() stringByAppendingString:@"/Documents/Score.db"];
    NSFileManager *manager = [NSFileManager defaultManager];
    NSError *error = nil;
    if ([manager fileExistsAtPath:path]) {
        BOOL isRemove = [manager removeItemAtPath:path error:&error];
        if (isRemove) {
            // 删除成功后重新创建table 防止测试时新增字段
            [self createTable];
            
            return YES;
        }
        else {
            NSLog(@"%@", error);
            
            return NO;
        }
    }
    else {
        return YES;
    }
}

• 2-6.按钮操作添加数据

• • 2-6-1.回合结束按钮 构造数据

    NSDictionary *littleScoreDic = @{@"redScore":@(self.leftScoreView.currentIndex), @"blueScore":@(self.rightScoreView.currentIndex), @"roundEndTime":[RBTool getCurrentDateWithFormat:@"yyyy-MM-dd HH:mm:ss"]};
    [self.littleArray addObject:littleScoreDic];

• • 2-6-2.比赛结束按钮 添加数据

    RBScoreModel *model = [[RBScoreModel alloc] init];
    model.date = [RBTool getCurrentDateWithFormat:@"yyyy-MM-dd HH:mm:ss"];
    model.redName = self.leftTeamView.nameText;
    model.redScore = self.leftBigScoreTF.text.length == 0?0:self.leftBigScoreTF.text.integerValue;
    model.blueName = self.rightTeamView.nameText;
    model.blueScore = self.rightBigScoreTF.text.length == 0?0:self.rightBigScoreTF.text.integerValue;
    model.gameType = self.gameType;
    NSString *content = [RBTool convertObjectToJson:self.littleArray];
    model.content = content;
    [[FMDBManager sharedDBManager] addScoreModel:model];

至此，文章就该结束了，但是我发现很多人不太会使用比赛记分牌，所以文章末尾添加了比赛记分牌的使用方法。

使用方法：

以乒乓球比赛为例:
1.使用顺序，选择比赛类型，输入比赛双方的队名，摇先手，看谁先发球，然后赢得一方加分数，本回合结束点击按钮回合结束，比赛结束点击比赛结束。
2.“+”按钮用于增加分数，“-”按钮减少分数，“重置”按钮用于重置分数。
3.小比分是大框的比分，代表一个回合的比分；大比分是小框的比分，代表一局比赛的比分。“回合结束”表示一回合（一局）比赛结束，小比分清空，小比分多的一队大比分加1；“比赛结束”表示本局比赛结束，比赛比分全部重置。
4.比赛结束后默认跳转到比赛结果列表，可查看比赛结果。
