1、上效果图：
这里写图片描述

2、
第一个是显示的7.2分的评分
第二个可以点击选择评分

3、主要代码：

- (void)creatStarView{    UIImage *gray   = [UIImage imageNamed:@"starGrey"];    UIImage *yellow = [UIImage imageNamed:@"strayellow"];    //1.获取星星视图的初始宽高    CGFloat width  = gray.size.width *5;    CGFloat height = gray.size.height;    //2.初始化星星视图    _grayView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height)];    [_grayView setBackgroundColor:[UIColor colorWithPatternImage:gray]]; // 平铺    [self addSubview:_grayView];    _yellowView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height)];    [_yellowView setBackgroundColor:[UIColor colorWithPatternImage:yellow]]; // 平铺    [self addSubview:_yellowView];    //3.放大星星视图与self等高等宽    CGFloat scaleW = self.frame.size.width/width;    CGFloat scaleH = self.frame.size.height/height;    _grayView.transform   = CGAffineTransformMakeScale(scaleW, scaleH);    _yellowView.transform = CGAffineTransformMakeScale(scaleW, scaleH);    //4.重置星星视图坐标    _grayView.frame   = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);    _yellowView.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);}-(void)setRating:(float)rating{//    _rating = rating;    _yellowView.frame = CGRectMake(0, 0, self.frame.size.width *rating/10, self.frame.size.height);}
