1，首先新建视图控制器

2，在视图控制器中铺上5*5的小格，每个格都是一个新View，全部添加到视频控制器上

3，当点击时调用系统触摸方法，可以把实现关灯的方法写在触摸方法里

代码如下：

先铺格

- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.        self.view.backgroundColor = [UIColor blackColor];        for (int i = 0; i < 5; i++) {        for (int j = 0; j < 5; j++) {            UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(35 + j * 50, 40 + i * 50, 50, 50)];            [self.view addSubview:view1];            view1.layer.borderWidth = 0.5;            view1.backgroundColor = [UIColor whiteColor];            view1.tag += 10000 + j + i * 100;            [view1 release];        }    }}

触摸

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    UITouch *touch = [touches anyObject];        int array[] = {0, 1, -1, 100, -100};    int count = sizeof(array) / sizeof(array[0]);        for (int i = 0; i < count; i++) {        UIView *view = (UIView *)[self.view viewWithTag:(touch.view.tag + array[i])];        if ([view.backgroundColor isEqual:[UIColor whiteColor]]) {            view.backgroundColor = [UIColor clearColor];        } else if ([view.backgroundColor isEqual:[UIColor clearColor]]) {            view.backgroundColor = [UIColor whiteColor];        }    }    }

关灯游戏之图片换图片：

- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.        self.view.backgroundColor = [UIColor blackColor];    for (int i = 0; i < 5; i++) {        for (int j = 0; j < 5; j++) {            UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(35 + j * 50, 40 + i * 50, 50, 50)];            imageView.userInteractionEnabled = YES;            [self.view addSubview:imageView];                        UIImage *image = [UIImage imageNamed:@"1.jpg"];            imageView.image = image;            imageView.layer.borderWidth = 0.5;            imageView.tag += 10000 + j + i * 100;            [imageView release];        }    }}

// 触摸- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    UITouch *touch = [touches anyObject];        int array[] = {0, 1, -1, 100, -100};    int count = sizeof(array) / sizeof(array[0]);    UIImage *image1 = [UIImage imageNamed:@"1.jpg"];    UIImage *image2 = [UIImage imageNamed:@"2.jpg"];        for (int i = 0; i < count; i++) {        UIImageView *view = (UIImageView *)[self.view viewWithTag:(touch.view.tag + array[i])];        if ([view isKindOfClass:[UIImageView class]]) {                        if ([view.image isEqual:image1]) {                view.image = image2;            } else {                view.image = image1;            }        }    }    }
