//星级

[self.startView setStarLevelFormStr:model.starCurrent];

- (void)createUI{

//在当前图片上放置五星级图片

UIImageView * upImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 65, 23)];

upImageView.tag = 2000;

upImageView.image = [UIImage imageNamed:@"StarsForeground"];

[self addSubview:upImageView];

//执行切割多余部分的操作

upImageView.clipsToBounds = YES;

//停靠模式 使五星级图片停靠在父视图的左侧 不设置会自动拉伸

upImageView.contentMode = UIViewContentModeLeft;

}

- (void)setStarLevelFormStr:(NSString *)level{

//更改五星级图片

UIImageView * imageView = (UIImageView *)[self viewWithTag:2000];

//@"4.5"->float4.5

imageView.frame = CGRectMake(0, 0, (level.doubleValue/5.0)*65, 23);
