Overview

Core Animation adds two additional properties to the CIFilter class. These properties are accessible through key-value coding as well as the properties declared below.

Tasks

Enabling Filter Instances

name

The name of the receiver.

@property(copy) NSString *name
Discussion

Default is nil. Each CIFilter instance can have an assigned name. The name is used to construct key paths to the filter’s attributes. For example, if a CIFilter instance has the name “myExposureFilter”, you refer to attributes of the filter using a key path such as “filters.myExposureFilter.inputEV”. Layer animations may also access filter attributes via these key paths.
