RKRoute Class Reference
Inherits from | NSObject |
Declared in | RKRoute.h |
Overview
The RKRoute
class models a single routable path pattern in use by the application. A route can be combined with an NSURL
base URL and interpolated with an object to produce a new fully hydrated URL object. Routes are always instantiated with a path pattern and metadata to provide for the subsequent identification of the defined route.
There are three types of routes modeled by the RKRoute class:
- Named Routes: A named route represents a single path and optional request method within the application. The route is not affiliated with any particular class. For example, one might define a route with the name
@"airlines_list"
as a GET to the path ‘/airlines.json’. - Class Routes: An class route represents a single path that is identified by object class and request method for which it is appropriate. For example, one might define a route for the class
RKArticle
for a POST to the path ‘/articles.json’. - Relationship Routes: A relationship route represents a single path through which the relationship of a parent object can be manipulated. For example, given an
RKArticle
andRKComment
class, one might define a relationship route for theRKArticle
class’s@"comments"
relationship as pointing to a GET to the path `@“/articles/:articleID/comments”.
The RKRoute class is internally implemented as a class cluster and is not to be directly instantiated via alloc and init.

property
Inspecting Route Types
-
– isNamedRoute
Determines if the receiver is a named route.
-
– isClassRoute
Determines if the receiver is a class route.
-
– isRelationshipRoute
Determines if the receiver is a relationship route.
Properties
method
The request method of the receiver.
@property (nonatomic, assign, readonly) RKRequestMethod method
Discussion
Appropriate for all route types. If the route is appropriate for any HTTP request method, then the RKRequestMethodAny
value is used.
Declared In
RKRoute.h
name
The name of the receiver.
@property (nonatomic, strong, readonly) NSString *name
Discussion
The name is used to identify named and relationship routes and is always nil
for object routes.
Declared In
RKRoute.h
objectClass
The object class of the receiver.
@property (nonatomic, strong, readonly) Class objectClass
Discussion
Defines the class for which the route is appropriate. Always returns nil
for named routes.
Declared In
RKRoute.h
