iOS--九宫格奥秘(UIView)(arc4random)

 下面程序主要实现,九宫格的模型,每个小UIView的颜色随机产生的,用到了 arc4random函数:

int x=50;

    int y=50;

    int width=50;

    int height=50;

    for (int i=0; i<3; i++) {

        for (int j=0; j<3; j++) {

            UIView *tempView=[[UIView alloc]initWithFrame:CGRectMake(x+j*55, y+i*55, width, height)];

//            tempView.backgroundColor=[UIColor redColor];

            tempView.backgroundColor=[UIColor colorWithRed:(arc4random()%256/256.0) green:(arc4random()%128/256.0) blue:(arc4random()%128/256.0) alpha:2.0];

            [self.view addSubview:tempView];

        }

    }

 

程序结果如图:
