关灯游戏无限关

思路:在一个view上建两层button 然后改变最上面一层的背景颜色

效果图

这里用了button 分类

//声明@interface UIButton (CategoryButton)+ (UIButton *)roundRectButtonWithFrame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action;+ (UIButton *)buttonWithType:(UIButtonType)type frame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action;@end

//实现

@implementation UIButton (CategoryButton)+ (UIButton *)roundRectButtonWithFrame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action{        return [UIButton buttonWithType:UIButtonTypeRoundedRect frame:frame title:title target:target action:action];    }+ (UIButton *)buttonWithType:(UIButtonType)type frame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action{    UIButton *button = [UIButton buttonWithType:type];    button.frame = frame;    [button setTitle:title forState:UIControlStateNormal];    [button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];    button.layer.borderWidth=4;    button.layer.contentsScale=5;    return button;    }@end

//root.h文件

@interface RootViewController : UIViewController@property(assign,nonatomic)int state;// 灯的状态@property(assign,nonatomic)int RandomClick;//随机点击次数@end

//实现

- (void)viewDidLoad{    [super viewDidLoad];    //    添加背景图片//    UIView *registeredView=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];//    UIImage *img=[UIImage imageNamed:@"2.png"];//    [registeredView setBackgroundColor:[UIColor colorWithPatternImage:img]];//    设置背景颜色//    registeredView.backgroundColor=[UIColor redColor];//    [self.view addSubview:registeredView];    CGFloat x=0;    CGFloat y=0;        UIView *downView = [[UIView alloc]initWithFrame:self.view.frame];    [self.view addSubview:downView];//    downView.tag = 10000;        UIView *downView2 = [[UIView alloc]initWithFrame:self.view.frame];    [self.view addSubview:downView2];    downView2.tag = 20000;        for (int i=1; i<6; i++) {        for (int j=1; j<6; j++) {            UIButton *button1=[UIButton roundRectButtonWithFrame:CGRectMake(x, y, 64, 96) title:@"" target:self action:@selector(offLamp:)];            button1.backgroundColor=[UIColor orangeColor];            [downView addSubview:button1];                        UIButton *button=[UIButton roundRectButtonWithFrame:CGRectMake(x, y, 64, 96) title:@"" target:self action:@selector(offLamp:)];            button.backgroundColor=[UIColor redColor];            [downView2 addSubview:button];            button.tag =i*100+j;//            显示button上的tag值//            NSString* str = [NSString stringWithFormat:@"%d",button1.tag];//            [button1 setTitle:str forState:UIControlStateNormal];//            NSLog(@"%d",button.tag);//            添加图片,并改变背景的状态//            [button setBackgroundImage:[UIImage imageNamed:@"imgage.png"] forState:UIControlStateSelected];                     x+=64;        }        x=0;        y+=96;            }    [self initWith];}//初始化-(void)initWith{    for (int i=0; i<1+self.RandomClick; i++) {        UIButton * button1=(UIButton*)[self.view viewWithTag:(arc4random()%5+1)*100+arc4random()%5+1];        [self offLamp:button1];    }    }//过关并进入下一关-(void)win{    self.state = 0;    UIView *view = [self.view viewWithTag:20000];    for (UIButton *but in [view subviews]) {        if (but.backgroundColor == [UIColor redColor]) {            self.state++;        }        if (self.state==25) {            UIAlertView *aView = [[UIAlertView alloc]initWithTitle:@"恭喜你" message:@"你过关了" delegate:self cancelButtonTitle:@"下一关" otherButtonTitles:nil];            [aView show];            self.RandomClick++;            [self initWith];        }    }}//点击事件/这里如果用seleated还可以优化-(void)offLamp:(UIButton *)button{    if (button.backgroundColor==[UIColor redColor]) {        button.backgroundColor=[UIColor clearColor];    }else{        button.backgroundColor=[UIColor redColor];    }    UIView *button1=[self.view viewWithTag:button.tag+100];        if (button1.backgroundColor==[UIColor redColor]) {        button1.backgroundColor=[UIColor clearColor];    }else{        button1.backgroundColor=[UIColor redColor];    }        UIView *button2=[self.view viewWithTag:button.tag-100];    if (button2.backgroundColor==[UIColor redColor]) {        button2.backgroundColor=[UIColor clearColor];    }else{        button2.backgroundColor=[UIColor redColor];    }    UIView *button3=[self.view viewWithTag:button.tag+1];    if (button3.backgroundColor==[UIColor redColor]) {        button3.backgroundColor=[UIColor clearColor];    }else{        button3.backgroundColor=[UIColor redColor];    }    UIView *button4=[self.view viewWithTag:button.tag-1];    if (button4.backgroundColor==[UIColor redColor]) {        button4.backgroundColor=[UIColor clearColor];    }else{        button4.backgroundColor=[UIColor redColor];    }    [self win];}
