构建颜色字典构建back view 赋值背景颜色对颜色进行遍历－－－－在循环体里 ColorStripe 创建UILable定义位置和大小将字典中的颜色取出来赋给UIlable的背景颜色将UIlable送到view中 ColorNameLable 构建字体UILable并且定义位置设置字体和大小设置字体的颜色为背景颜色设置字体的对齐方式设置字体的熟知将Lable送到View中

控件的位置由frame属性决定每一个控件在创立的时候可以指定frame frame是CGRect结构的包含x，y，width，height四个浮点型 frame是相对父视图而言

颜色：UIColor()，颜色值为小数（0..1）归一到255. UILabel CGRectMake()创建框架。

UIView(frame): 创建一个视图 CGRectMake(x,y,width,height): 创建一个矩形 CGFloat: 浮点值的基本类型 CGPoint: 表示一个二维坐标系中的点 CGSize: 表示一个矩形的宽度和高度 CGRect: 表示一个矩形的位置和大小
