三、游戏棋盘的设计
创建一个继承于UIView的类，作为五子棋游戏的棋盘，命名为GameView实现如下：
GameView.h
#import <UIKit/UIKit.h>
#import "TipButton.h"
#import "BlueToothTool.h"
//用于处理用户下子后的逻辑
@protocol GameViewDelegate<NSObject>
-(void)gameViewClick:(NSString *)index;
@end
@interface GameView : UIView<UIAlertViewDelegate>
//存放所有棋格
@property(nonatomic,strong)NSMutableArray<TipButton *> * tipArray;
@property(nonatomic,weak)id<GameViewDelegate>delegate;
//进行下子
-(void)setTipIndex:(int)index;
@end
GameView.m
#import "GameView.h"
@implementation GameView
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_tipArray = [[NSMutableArray alloc]init];
[self creatView];
}
return self;
}
//创建表格视图 横16 竖20
-(void)creatView{

self.layer.borderWidth = 0.5;
CGFloat width = self.frame.size.width/12;
CGFloat height = self.frame.size.height/20;
//排列布局
for (int i=0; i<240; i++) {
TipButton * btn = [[TipButton alloc]initWithFrame:CGRectMake(width*(i%12), height*(i/12), width, height)];
[btn addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
btn.isWhite = NO;
btn.index=i;
[self addSubview:btn];
[_tipArray addObject:btn];
}
}
-(void)click:(TipButton *)btn{
if (btn.hasChess==0) {
//下子
[btn dropChess:YES];
//进行胜负判定
[self cheak];
[self.delegate gameViewClick:[NSString stringWithFormat:@"%d",btn.index]];
}
}

关于胜负判定的算法逻辑，这里采用了向各个方向进行递归查找的方式，这里有一点需要主要，在4个方向进行递归查找时，理论上每个方向只需要单面递归即可，但是代码中采用了双面递归在进行累加的方式，这样的设计可以遍历更少的棋子判定出胜负情况。
四、整合通讯与游戏逻辑
创建一个继承于UIViewController的类作为游戏视图控制器，实现如下：
GameViewController.m
#import "GameViewController.h"
#import "GameView.h"
#import "BlueToothTool.h"
@interface GameViewController ()<BlueToothToolDelegate,GameViewDelegate>
{
UIView * _bgView;
UILabel * _tipLabel;
GameView * _view;
}
@end
@implementation GameViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor brownColor];
//创建游戏视图
_view = [[GameView alloc]initWithFrame:CGRectMake(20, 40, (self.view.frame.size.width-40), (self.view.frame.size.width-40)/12*20)];
_view.delegate=self;
[self.view addSubview:_view];
//创建背景视图
_bgView = [[UIView alloc]initWithFrame:self.view.frame];
_bgView.backgroundColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:0.1];
UIButton * btn = [UIButton buttonWithType:UIButtonTypeSystem];
btn.frame = CGRectMake(self.view.frame.size.width/2-50, 150, 100, 30);
UIButton * btn2 = [UIButton buttonWithType:UIButtonTypeSystem];
btn2.frame = CGRectMake(self.view.frame.size.width/2-50, 250, 100, 30);
[btn setTitle:@"创建游戏" forState:UIControlStateNormal];
[btn2 setTitle:@"扫描附近游戏" forState:UIControlStateNormal];
btn.backgroundColor = [UIColor orangeColor];
btn2.backgroundColor = [UIColor orangeColor];
[btn addTarget:self action:@selector(creatGame) forControlEvents:UIControlEventTouchUpInside];
[btn2 addTarget:self action:@selector(searchGame) forControlEvents:UIControlEventTouchUpInside];
[_bgView addSubview:btn];
[_bgView addSubview:btn2];
[self.view addSubview:_bgView];
//设置蓝牙通讯类代理
[BlueToothTool sharedManager].delegate=self;
//创建提示标签
_tipLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,40)];
[self.view addSubview:_tipLabel];
_tipLabel.textAlignment = NSTextAlignmentCenter;
}
-(void)creatGame{
[[BlueToothTool sharedManager]setUpGame:@"" block:^(BOOL first) {
[_bgView removeFromSuperview];
if (first) {
_tipLabel.text = @"请您下子";
//进行发送下子信息
}else{
_tipLabel.text = @"请等待对方下子";
self.view.userInteractionEnabled = NO;
[self gameViewClick:@"-1"];
}
}];
}
-(void)searchGame{
[[BlueToothTool sharedManager]searchGame];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)getData:(NSString *)data{
if (_bgView.superview) {
[_bgView removeFromSuperview];
}
if ([data integerValue]==-1) {
_tipLabel.text = @"请您下子";
self.view.userInteractionEnabled = YES;
return;
}
_tipLabel.text = @"请您下子";
[_view setTipIndex:[data intValue]];
self.view.userInteractionEnabled = YES;
}
-(void)gameViewClick:(NSString *)index{
_tipLabel.text = @"请等待对方下子";
[[BlueToothTool sharedManager]writeData:index];
self.view.userInteractionEnabled = NO;
}
@end
游戏运行的主要界面如下图所示：
