简易的关灯游戏设计

//初始化
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.isOpen = YES;
self.backgroundColor = [UIColor whiteColor];

}
return self;
}

//改变自己的颜色
- (void)exchange
{
self.backgroundColor = _isOpen ? [UIColor blackColor]:[UIColor whiteColor];
_isOpen = !_isOpen;
}
//改变周围的颜色
- (void)suroundChange
{
TouchView *left = (TouchView *)[self.superview viewWithTag:self.tag - 1];
TouchView *right = (TouchView *)[self.superview viewWithTag:self.tag + 1];

TouchView *up = (TouchView *)[self.superview viewWithTag:self.tag - 20];
TouchView *down = (TouchView *)[self.superview viewWithTag:self.tag + 20];
[left exchange];
[right exchange];
[up exchange];
[down exchange];
}
//点击实现颜色的跳转
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"自己的tag:%ld",self.tag);
[self exchange];
[self suroundChange];
}

视图控制器里面的实现:
MainViewController *main = [[MainViewController alloc]init];
self.window.rootViewController = main;
[main release];

//实现6*8的视图:(在主视图控制器里实现) Length是定义的宏:
for (NSInteger i = 0; i < 48; i++) {
TouchView *touch = [[TouchView alloc]initWithFrame:CGRectMake(5 + i % 6 * Length, 25 + i / 6 * Length , Length - 1, Length - 1)];
touch.tag = 100 + i / 6 * 20 + i % 6;
[self.view addSubview:touch];
[touch release];
}
