使用的库:TPFloatRatingView

只要设置一下参数就好了：

self.starView = [[TPFloatRatingView alloc] init];
self.starView.frame = CGRectMake(kLeft30, 50, 100, 15);
self.starView.frame = CGRectMake(0, 0, starsWidth, starsHeight);
self.starView.emptySelectedImage = [UIImage imageNamed:@"star_grey"];
self.starView.fullSelectedImage = [UIImage imageNamed:@"star_light"];
self.starView.rating = self.starNum;
self.starView.maxRating = 5;
self.starView.minRating = 0;
self.starView.editable = NO;
self.starView.halfRatings = YES;
self.starView.floatRatings = YES;
[self.starview addSubview:self.starView];

如果需要编辑星星的话，就要使用TPFloatRatingViewDelegate：

- (void)floatRatingView:(TPFloatRatingView *)ratingView ratingDidChange:(CGFloat)rating
{
    self.starnumber = rating;
}
- (void)floatRatingView:(TPFloatRatingView *)ratingView continuousRating:(CGFloat)rating
{
    self.starnumber = rating*2;
    if (rating==0) {
        self.titleLabel.text = @"打个分吧~";
    }else if (rating==1){
        self.titleLabel.text = @"很差!";
    }else if (rating==2){
        self.titleLabel.text = @"较差!";
    }else if (rating==3){
        self.titleLabel.text = @"一般!";
    }else if (rating==4){
        self.titleLabel.text = @"挺好!";
    }else{
        self.titleLabel.text = @"很棒!";
    }
}

// Create image info
JTSImageInfo *imageInfo = [[JTSImageInfo alloc] init];
imageInfo.image = image;
imageInfo.referenceRect = self.view.window.frame;
imageInfo.referenceView = self.view.window.superview;
// Setup view controller
JTSImageViewController *imageViewer = [[JTSImageViewController alloc]
                                       initWithImageInfo:imageInfo
                                       mode:JTSImageViewControllerMode_Image
                                       backgroundStyle:JTSImageViewControllerBackgroundOption_Blurred];
// Present the view controller.
imageViewer.interactionsDelegate  = self;
[imageViewer showFromViewController:self transition:JTSImageViewControllerTransition_FromOffscreen];

使用JTSImageViewControllerInteractionsDelegate:
