How can I get Apple default filters and Can I add new Apple filter if not found.
Hi, 1- How can I get the new Apple default filters
// Get only the core image filters.
NSArray *filterTypes = [NBUFilterProvider availableFilters];
2- Can I add new Apple filter if not found ? https://developer.apple.com/library/mac/documentation/GraphicsImaging/Reference/CoreImageFilterReference/index.html#//apple_ref/doc/filter/ci/CIMinimumCompositing
You would need to make a new entry for the filter you want here.
First find out the available filters with [CIFilter filterNamesInCategories:nil], then check its attributes [CIFilter filterWithName:@"CIMinimumCompositing"].attributes.
Try to do that and open a pull request with a first version so we can take a look together.
Is there any way I can use more default iOS filter effects without changing code in pod.

Not without changing the code because the library wraps the filters so you can mix CoreImage filters with GPUImage filters, etc.
