Methods

createCollection(token:withTitle:alias:completion:)

Creates a new collection.

public func createCollection(token: String? = nil, withTitle title: String, alias: String? = nil, completion: @escaping (Result<WFCollection, Error>) -> Void)

If only a title is given, the server will generate and return an alias; in this case, clients should store the returned alias for future operations.

Parameters

• token: - token: The access token for the user creating the collection.
• title: - title: The title of the new collection.
• alias: - alias: The alias of the collection.
• completion: - completion: A handler for the returned WFCollection on success, or Error on failure.

getCollection(token:withAlias:completion:)

Retrieves a collection's metadata.

public func getCollection(token: String? = nil, withAlias alias: String, completion: @escaping (Result<WFCollection, Error>) -> Void)

Collections can be retrieved without authentication. However, authentication is required for retrieving a private collection or one with scheduled posts.

Parameters

• token: - token: The access token for the user retrieving the collection.
• alias: - alias: The alias for the collection to be retrieved.
• completion: - completion: A handler for the returned WFCollection on success, or Error on failure.

deleteCollection(token:withAlias:completion:)

Permanently deletes a collection.

public func deleteCollection(token: String? = nil, withAlias alias: String, completion: @escaping (Result<Bool, Error>) -> Void)

Any posts in the collection are not deleted; rather, they are made anonymous.

Parameters

• token: - token: The access token for the user deleting the collection.
• alias: - alias: The alias for the collection to be deleted.
• completion: - completion: A hander for the returned Bool on success, or Error on failure.

getPosts(token:in:completion:)

Retrieves an array of posts.

public func getPosts(token: String? = nil, in collectionAlias: String? = nil, completion: @escaping (Result<[WFPost], Error>) -> Void)

If the collectionAlias argument is provided, an array of all posts in that collection is retrieved; if omitted, an array of all posts created by the user whose access token is provided is retrieved.

Collection posts can be retrieved without authentication; however, authentication is required for retrieving a private collection or one with scheduled posts.

Parameters

• token: - token: The access token for the user retrieving the posts.
• collectionAlias: - collectionAlias: The alias for the collection whose posts are to be retrieved.
• completion: - completion: A handler for the returned [WFPost] on success, or Error on failure.

movePost(token:postId:with:to:completion:)

Moves a post to a collection.

public func movePost(token: String? = nil, postId: String, with modifyToken: String? = nil, to collectionAlias: String, completion: @escaping (Result<Bool, Error>) -> Void)

Attention: - The closure should return a result type of `<[WFPost], Error>`.

• The modifyToken for the post is currently ignored.

Parameters

• token: - token: The access token for the user moving the post to a collection.
• postId: - postId: The ID of the post to add to the collection.
• modifyToken: - modifyToken: The post's modify token; required if the post doesn't belong to the requesting user.

Pinning a post to a collection adds it as a navigation item in the collection/blog home page header, rather than on the blog itself. While the API endpoint can take an array of posts, this function only accepts a single post.

Parameters

• token: - token: The access token of the user pinning the post to the collection.
• postId: - postId: The ID of the post to be pinned.
• position: - position: The numeric position in which to pin the post; if nil, will pin at the end of the list.

• completion: - completion: A handler for the Bool returned on success, or Error on failure.

unpinPost(token:postId:from:completion:)

Unpins a post from a collection.

public func unpinPost(token: String? = nil, postId: String, from collectionAlias: String, completion: @escaping (Result<Bool, Error>) -> Void)

Removes the post from a navigation item and puts it back on the blog itself. While the API endpoint can take an array of posts, this function only accepts a single post.

Parameters

• token: - token: The access token of the user un-pinning the post from the collection.
• postId: - postId: The ID of the post to be un-pinned.
• collectionAlias: - collectionAlias: The alias of the collection to which the post should be un-pinned.
