open class PhotoEditToolController : ViewController

A PhotoEditToolController is the base class for any tool controller. Tool controllers can be presented in a PhotoEditViewController and are displayed above a PhotoEditPreviewController.

  • Creates a new PhotoEditToolController with the given configuration. This initializer must be implemented by each PhotoEditToolController subclass and is the initializer that gets called when a tool is instantiated by the framework.

    Declaration

    Swift

    public required init?(configuration: Configuration, productType: LicenseProduct)

    Parameters

    configuration

    A Configuration object.

    productType

    The product that this tool is used in.

  • The ToolbarItem that is displayed in the Toolbar of a PhotoEditViewController when this tool is pushed onto the stack.

    Declaration

    Swift

    open lazy var toolbarItem: ToolbarItem { get set }
  • Configures the toolbarItem. Subclasses can override this to do any custom configuration.

    Declaration

    Swift

    open func configureToolbarItem()
  • Called when the apply button is tapped. This sends a viewControllerDidFinish(_:) message to subscribers.

    Declaration

    Swift

    open func apply(_ sender: ToolbarItem)

    Parameters

    sender

    The toolbar item that called this method.

  • Called when the discard button is tapped. This sends a viewControllerDidCancel(_:) message to subscribers.

    Declaration

    Swift

    open func discard(_ sender: ToolbarItem)

    Parameters

    sender

    The toolbar item that called this method.

  • The photo edit model. Changing this sends a photoEditModelDidChange(_:) message to subscribers.

    Declaration

    Swift

    open var photoEditModel: PhotoEditModel { get set }
  • The unedited photo edit model without any changes applied.

    Declaration

    Swift

    public private(set) var uneditedPhotoEditModel: PhotoEditModel
  • Called when the photo edit model changes.

    Declaration

    Swift

    open func photoEditModelDidChange(from oldModel: PhotoEditModel, to newModel: PhotoEditModel)

    Parameters

    oldModel

    The previous photo edit model, before the update.

    newModel

    The new photo edit model, after the update.

  • The configuration object that configures this tool.

    Declaration

    Swift

    public let configuration: Configuration
  • An object that acts as a delegate.

    Declaration

    public var assetCatalog: AssetCatalog { get set }
  • A UserInteraceState can be used by a tool to restore any previous state when being initialized and to pass updated state back to the subscriber.

    Declaration

    Swift

    open var userInterfaceState: UserInterfaceState { get set }
  • Asks the tool to update its user interface state if required. By default this method does nothing.

    Declaration

    Swift

    open func updateUserInterfaceState()

    open override func willBecomeActiveTool()
  • Notifies the tool controller that it became the active tool.

    Important

    Declaration

    Swift

    open override func didBecomeActiveTool()
  • Notifies the tool controller that it is about to resign being the active tool.

    Note

    This method will not be called if another tool is pushed above this tool. It is only called if you pop the tool from the photo edit view controller.

    Declaration

    Swift

    open override func willResignActiveTool()
