iOS 类似2048、4096小游戏-OC

大概思路(初步制作，粗工制造)：demo

1、Collection 创建cell

2、cell上添加一个view，用来添加手势

3、字典用来存放数据-》每次执行StarGame数组接收没有数字的字典，原来字典对应的删除-》随机选中改变数组-》插回原来数据-》每次滑动 用选择排序分别相加相邻且相等的数据后，再用选择排序 进行排序（详情下文）-》刷新cell-》♻️

 

//数据
NSMutableDictionary * dictChange;//放 数值为0（代表没有数值的位置） 的字典
 UISwipeGestureRecognizer * recognizer;//滑动手势
   NSMutableDictionary * dictData;//数据字典

// 先添加 初始数据
-(void)creaDATA{

    dictData = [NSMutableDictionary dictionary];
    for (int i=; i<; i++) {

        [dictData setObject:@"" forKey:@(i)];

    }

}

-(void)StarGame{
    //筛选出 模块上可以添加数据的 位置字典。装到数组，随机分配
    dictChange = [NSMutableDictionary dictionary];
    for (int i=; i<; i++) {
        NSString * str = [dictData objectForKey:@(i)];
        if ([str isEqualToString:@""]) {

            [dictChange setObject:@"" forKey:@(i)];

        }

    }

    //先判断有没有满足要求
    NSArray * value = [dictData allValues];
    if ([value containsObject:_GameNum]) {
        NSInteger haomiao,miao,fen;

        haomiao = timernumber%;
        miao = timernumber/;
        fen = miao/;

        [UIView pushAlertTwoActionViewWithMessage:[NSString stringWithFormat:@"恭喜你，完成游戏\n用时：%02ld:%02ld:%02ld",fen,miao,haomiao] Target:self Title:@"OH耶！！！" oneAlertTitle:@"挑战时间" twoAlertTitle:@"休息一下" oneActionfunc:^{
            //继续
            [dictData removeAllObjects];
            [collectionvieww reloadData];
            timernumber = ;
            [self StarGame];
            [self timerStar];

        } twoActionfunc:^{

            //返回上一页

        }];

    }

    //如果没有位置可以再添加数字了 游戏就结束了
    if (dictChange.count ==) {
        [timerss invalidate];
        timerss = nil;

           [UIView pushAlertTwoActionViewWithMessage:@"游戏结束" Target:self Title:@"再挑战一局吧" oneAlertTitle:@"好的" twoAlertTitle:@"休息一下" oneActionfunc:^{
               //继续
               [dictData removeAllObjects];
               [collectionvieww reloadData];
               timernumber = ;
               [self StarGame];
               [self timerStar];

           } twoActionfunc:^{

               //返回上一页

           }];
        return;
    }

    //随机添加数据。刷新表格
    int random = (int)( (arc4random() % (dictChange.count)));
    NSArray * dictKey = [dictChange allKeys];
    [dictChange setObject:@"" forKey:dictKey[random]];
    //返回给数据字典
    for (NSString * key in dictKey) {

        [dictData setObject:dictChange[key] forKey:key];

    }
    [dictChange removeAllObjects];
    //刷新表
    [collectionvieww reloadData];

}

每次插入数字时

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(silidingTop)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
    [frontView addGestureRecognizer:recognizer];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(silidingLift)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
    [frontView addGestureRecognizer:recognizer];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(silidingDown)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];
    [frontView addGestureRecognizer:recognizer];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(silidingRight)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
    [frontView addGestureRecognizer:recognizer];

上左下右 手势添加

-(void)silidingLift{

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, ), ^{
        for (int h = ; h<; h++) {

            //选择 筛选相邻数字相加。只相加一次
            for (int i=; i<; i++) {

                if (![dictData[@(i+*h)] isEqualToString:@""])

                {

                    for (int j=i+; j<; j++) {

                        if (![dictData[@(j+*h)] isEqualToString:@""]){

                            if ([dictData[@(i+*h)] isEqualToString: dictData[@(j+*h)]]) {

                                //后边的数是 相加后的值
                                [dictData setObject:[NSString stringWithFormat:@"%d",[dictData[@(j+*h)] intValue] + [dictData[@(i+*h)] intValue]] forKey:@(i+*h)];
                                [dictData setObject:@"" forKey:@(j+*h)];//前边的 设置为0

                            }
                            break; // 有了 就不再循环了

                        }
                    }

                }

                if (i==) {
                    [self Lift2:h];
                }

            }

        }

        dispatch_async(dispatch_get_main_queue(), ^{
            [collectionvieww reloadData];

            [self StarGame];
        });
    });

}

-(void)Lift2:(int)h{

    //选择排序  整理位置
    for(int i=;i<;i++){
        if ([dictData[@(i+*h)] isEqualToString:@""])//i为0 的时候
        {

            for (int j=i+; j<; j++)
            {
                if (![dictData[@(j+*h)] isEqualToString:@""]) //j 有值的时候

                    //i 的值 为j 的。j设置为0
                {

                    [dictData setObject:dictData[@(j+*h)] forKey:@(i+*h)];
                    [dictData setObject:@"" forKey:@(j+*h)];

                    break; // 继续下一次循环
                }

            }

        }

    }
