How to get the list of filter names in CIFilter class?

Question

I am using the following code for exposure adjustment and its working. I need the filter names for sharpen, denoise, highlighs, color temperature, shadows, blur, etc.

Answer 1

In Swift (4.2, at the time of writing this), you can use this code to get all filter names:

For filters in a specified category:

CIFilter.filterNames(inCategory: "Name_of_the_category")

For filters in specified categories:

CIFilter.filterNames(inCategories: ["Name_of_the_category_1", "Name_of_the_category_2"])

For filters in all categories, just pass nil either in inCategory or inCategories:

CIFilter.filterNames(inCategory: nil)

or

CIFilter.filterNames(inCategories: nil)

All the functions above returns an Array of the filter names in String values:

[ "CIAccordionFoldTransition", "CIAdditionCompositing", "CIAffineClamp", "CIAffineTile", "CIAffineTransform", "CIAreaAverage", "CIAreaHistogram"... ]
