Provided Methods

fn textFormattingViewController_didChangeValue( &self, view_controller: &UITextFormattingViewController, change_value: &UITextFormattingViewControllerChangeValue, )

where Self: Sized + Message,

Available on crate features UIResponder and UITextFormattingViewControllerChangeValue and UIViewController only.

Delegate method that will be invoked on any text formatting changes.

• Parameters:
• viewController: Text formatting controller in which action was performed.
• changeValue: Object describing the change made via view controller.

fn textFormattingViewController_shouldPresentFontPicker( &self, view_controller: &UITextFormattingViewController, font_picker: &UIFontPickerViewController, ) -> bool

where Self: Sized + Message,

Available on crate features UIFontPickerViewController and UIResponder and UIViewController only.

If implemented, text formatting will call this method before presenting font picker controller. Use this method to make any presentation modifications or to prevent presentation altogether.

If you decide to prevent presentation of font picker via text formatting controller, you may present provided font picker yourself. In this case, you will have to handle any font picker actions independently.

• Parameters:
• viewController: Text formatting controller that is attempting to present font picker controller
• fontPicker: Font picker controller that will be presented.
• Returns: Flag indicating if text formatting controller should present font picker.

fn textFormattingViewController_shouldPresentColorPicker( &self, view_controller: &UITextFormattingViewController, color_picker: &UIColorPickerViewController, ) -> bool

where Self: Sized + Message,

Available on crate features UIColorPickerViewController and UIResponder and UIViewController only.

If implemented, text formatting will call this method before presenting color picker controller. Use this method to make any presentation modifications or to prevent presentation altogether.

You may decide to prevent presentation of color picker via text formatting controller. In that case, you may present provided color picker controller yourself, but you will have to handle any actions in that controller separately.

• Parameters:
• viewController: Text formatting controller that is attempting to present font picker controller
• colorPicker: Color picker controller that will be presented.
• Returns: Flag indicating if text formatting controller should present font picker.

fn textFormattingDidFinish( &self, view_controller: &UITextFormattingViewController, )

where Self: Sized + Message,

Available on crate features UIResponder and UIViewController only.

Informs the delegate that user has dismissed text formatting view controller.
