// 先添加灰色的图片再添加橘色的图片

self.backgroundImage = [UIImageView alloc initWithFrame:CGRectMake(0, 0, 65, 23)];

self.backgroundImage.image = UIImage imageNamed:@"StarsBackground";

    self addSubview:self.backgroundImage;

self.foregroundImage = [UIImageView alloc initWithFrame:CGRectMake(0, 0, 65, 23)];

self.foregroundImage.image = UIImage imageNamed:@"StarsForeground";

    self addSubview:self.foregroundImage;

// 切割视图

self.foregroundImage.clipsToBounds = YES;

// 图片的停靠关系:左对齐

self.foregroundImage.contentMode = UIViewContentModeLeft;

// 实现星级的方法

• (void)setStarLevel:(NSString *)level

{

self.foregroundImage.frame = CGRectMake(0, 0, self.backgroundImage.frame.size.width * level.floatValue / 5, 23);
