为iPhone评分明星

Question

我一直在寻找一个五星评级控制一段时间，并没有找到一个可靠的解决方案。 这个问题：

Anyone know whether there is a 5-star rating component on iPhone?

提供了几个不再可用的项目链接，但我无法追踪它们。

编辑：我显然不善于追踪项目，但我认为我的部分问题仍然存在。这是更新后的链接http://code.google.com/p/s7ratingview/downloads/detail?name=s7ratingview-basic-release.zip

所以这个问题是2部分 - 那里有一个可靠的预制解决方案，你可以指导我吗？

是否更好/相当容易（是的，我意识到这两个方面存在冲突）成长我自己的解决方案？你能给我一些提示/资源吗？我理解子类化UIView和跟踪触摸事件的基本思想，将另一个图像的顶部图像展开为看起来像星星，但更多的方向会有所帮助。我已经在iphone上开发了一个星期不到一个星期，仍然需要一点手握。

Answer 1

您可以尝试DYRateView。我想尽可能多地重用Ray教程中的那个，但是它缺少一些功能，所以我自己做了一个。

您可以查看我的博客，了解有关如何在项目中使用DYRateView的更多详细信息：http://iappexperience.com/post/23227218867/dyrateview-a-simple-yet-powerful-rating-control-for。

Answer 2

尝试使用5星评级的Ray Wenderlich's自定义UIView。

您还可以尝试使用UISlider并提供最小/最大曲目图像。

Answer 3

您可以尝试DLStarRating的另一种方法，让您自定义星星下方的区域，检测触摸。

轻松获得明星遵循此准则并复制并粘贴到您的项目中并轻松运行。
