}
 
 
- (void)initWithViewWithTheSize:(CGSize)starSize margin:(CGFloat)starMargin
{

    }

}
 
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (!_clickTheStar) {
        return;
    }
    UITouch *touch = [touches anyObject];
    CGPoint touchPoint = [touch locationInView:self];
    UIImageView *imageView ;
    _stores = 0;
    for(int i=0; i<5; ++i){
        imageView = _starImageViewArray[i];
        if ((touchPoint.x > 0) && (touchPoint.x < self.bounds.size.width) && (touchPoint.y > 0) && (touchPoint.y < self.bounds.size.height)) {

    }
}
 
- (CGFloat)getCurrentSocore
{
    return_stores;
}
 
@end
 
 
声明方法如下:
 
- (IDSStarsScoreView *)starsView
{
    if (!_starsView) {
        if (IS_IPHONE_5 || IS_IPHONE_4_OR_LESS) {
            _starsView = [[IDSStarsScoreViewalloc] initWithStarSize:CGSizeMake(12,12margin:0.5score:4.0];
        }
        else {
            _starsView = [[IDSStarsScoreViewalloc] initWithStarSize:CGSizeMake(13,13margin: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];
}
