Instance Property

identity

The changes to a particular touch during its lifetime.

Declaration

@property(readonly, strong) id<NSObject, NSCopying> identity;

Discussion

While touch identities may be re-used, they are unique during the life of the touch, even when multiple devices are present.

Identity objects implement the NSCopying protocol so that they may be used as keys in an NSDictionary. Use isEqual: to compare two touch identities.
