@implementation IDSStarsScoreView

 

 

- (instancetype)initWithStarSize:(CGSize)size margin:(CGFloat)margin score:(CGFloat)starNum

{

    CGRect frame = CGRectMake(0, 0, size.width*5 + margin*4, size.height);

    _stores = starNum;

    _clickTheStar = NO;

    if (self = [superinitWithFrame:frame]) {

        [selfinitWithViewWithTheSize:size margin:margin];

    }

    returnself;

}

 

 

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

{

    _starImageViewArray = [[NSMutableArrayalloc] init];

    UIImageView *imageView;

    CGFloat starNum = _stores;

    for (int i=0; i<5; ++i) {

        if (starNum > 0.5) {

            imageView = [[UIImageViewalloc] initWithImage:[UIImageimageNamed:@"ic_yiqiwan_star1"]];

        }

        elseif (starNum > 0){

            imageView = [[UIImageViewalloc] initWithImage:[UIImageimageNamed:@"ic_yiqiwan_star3"]];

        }

        else {

            imageView = [[UIImageViewalloc] initWithImage:[UIImageimageNamed:@"ic_yiqiwan_star2"]];

        }

        imageView.frame = CGRectMake(self.bounds.origin.x+(i*starSize.width+i*starMargin), 0, starSize.width, starSize.height);

        [selfaddSubview:imageView];

        [_starImageViewArrayaddObject:imageView];

        --starNum;

    }

}

 

- (void)startInitWithScore:(CGFloat)starNum

{

    _stores = starNum;

    UIImageView *imageView;

    for (int i=0; i<5; ++i) {

        imageView = _starImageViewArray[i];

        if (starNum > 0.5) {

            imageView.image = [UIImageimageNamed:@"ic_yiqiwan_star1"];

        }

        elseif (starNum > 0){

            imageView.image = [UIImageimageNamed:@"ic_yiqiwan_star3"];

        }

        else {

            imageView.image = [UIImageimageNamed:@"ic_yiqiwan_star2"];

        }

        --starNum;

    }

}

 

- (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)) {

            if (imageView.frame.origin.x <= touchPoint.x) {

                ++_stores;

                imageView.image = [UIImageimageNamed:@"ic_yiqiwan_star1"];

            }

            else{

                imageView.image = [UIImageimageNamed:@"ic_yiqiwan_star2"];

            }

        }

    }

    if ([self.delegaterespondsToSelector:@selector(startsScoreView:didSelectedScore:)]) {

        [self.delegatestartsScoreView:selfdidSelectedScore:_stores];

    }

}

 

- (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(12,12)  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];

}
