声明方法如下：
- (IDSStarsScoreView *)starsView
{
if (!_starsView) {
if (IS_IPHONE_5 || IS_IPHONE_4_OR_LESS) {
_starsView = [[IDSStarsScoreViewalloc] initWithStarSize:CGSizeMake(12,12) margin:0.5score:4.0];
}
else {
_starsView = [[IDSStarsScoreViewalloc] initWithStarSize:CGSizeMake(13,13) margin:2score:4.0];
}
_starsView.frame = CGRectMake(CGRectGetMinX(self.scoreLabel.frame)-_starsView.frame.size.width-3, 0, _starsView.frame.size.width, _starsView.frame.size.height);
_starsView.centerY = self.scoreLabel.centerY;
}
return_starsView;
}
数据联调用法如下：
if (!IS_NS_STRING_EMPTY(model.gameInfo.score)) {
_scoreLabel.text = model.gameInfo.score;
[_scoreLabel sizeToFit];
_scoreLabel.frame = CGRectMake(self.bounds.size.width-10-_scoreLabel.contentSize.width,99, _scoreLabel.contentSize.width, _scoreLabel.contentSize.height);
_scoreLabel.centerY = self.soundImageView.centerY;
[_starsView startInitWithScore:model.gameInfo.score.floatValue];
}
