ios - 自定义图像滤镜和多种彩色滤镜

Question

我正在尝试为 iOS 应用程序实现一个类似于 LGBT 配色方案的过滤器(它是几条颜色条纹，一个在另一个之上)。有人对这个有经验么？我一直在到处寻找。我从 Ray Wenderlich 的教程( http://www.raywenderlich.com/76285/beginning-core-image-swift )开始创建了我的应用程序，但我没有看到有关制作自定义图像过滤器的任何内容。如果有人能指出我正确的方向，我将不胜感激!

谢谢:)

我们无法在 iOS 中自定义创建过滤器。

On OS X, if the filters provided by Core Image don’t provide the functionality you need, you can write your own filter. (Custom filters are not available on iOS.) You can include a filter as part of an application project, or you can package one or more filters as a standalone image unit. Image units use the NSBundle class and represent the plug-in architecture for filters.
