URLSessionEventHub

public final class URLSessionEventHub : NSObject
extension URLSessionEventHub: URLSessionTaskDelegate
extension URLSessionEventHub: URLSessionDataDelegate
extension URLSessionEventHub: URLSessionDownloadDelegate

Forwards callbacks from a URLSession to objects implementing URLSessionObserver. Assigns a single observer per URLSessionTask and that observer receives all callbacks associated with that task.

  • Undocumented

    Declaration

    Swift

    override public init()

  • Assigns an observer for a specific URLSessionTask. This unassigns the previous observer to the provided task. The new observer will receive all callbacks for task until it is explicitly removed from this instance, or, if task completes. A task is considered completed when 

    urlSession(:task:didCompleteWithError:)

    is invoked in which case the hub will forward this last call to its observer and then remove it.

    Declaration

    Swift

    public func setObserver(_ observer: URLSessionObserver, for task: URLSessionTask)

    Parameters

    observer

    An object that will receive all callbacks for task.
    task

    The task to associate with observer.

  • Removes the observer for a specific URLSessionTask, if one exists.

    Declaration

    Swift

    public func removeObserver(for task: URLSessionTask)

    Parameters

    task

    The task to stop observing.
