    typealias MGLOfflinePackAdditionCompletionHandler = (MGLOfflinePack?, Error?) -> Void

    Parameters

    pack

    Contains a pointer to the newly added pack, or nil if there was an error creating or adding the pack.
    error

    Contains a pointer to an error object (if any) indicating why the pack could not be created or added.

  • A block to be called once an offline pack has been completely invalidated and removed.

    Avoid any references to the pack inside this completion handler: by the time this completion handler is executed, the pack has become invalid, and any messages passed to it will raise an exception.

    Declaration

    Objective-C

    typedef void (^MGLOfflinePackRemovalCompletionHandler)(NSError *_Nullable)

    Swift

    typealias MGLOfflinePackRemovalCompletionHandler = (Error?) -> Void

    Parameters

    The file URL of the offline database containing the offline packs that were copied.
    packs

    An array of all known offline packs, or nil if there was an error creating or adding the pack.
