doCommand(by:command:)
Passes commands that are not generated as part of the text input process.
Declaration
func doCommand(by aSelector: Selector!, command infoDictionary: [AnyHashable : Any]!)Parameters
- aSelector:
A selector that represents a command from the text input menu.
- infoDictionary:
A dictionary that contains two key-value pairs:
Kimkcommandmenuitemname, whose value is an
NSMenuItemobject. That is, the item selected by the user.Kimkcommandclientname, whose value is the current client—
id<IMKTextInput, NSObject>.
Discussion
The default implementation checks if the input controller object (that is, self) responds to the selector. If so, it sends the message perform(_:with:) to the input controller class. The object parameter in that case is the infoDictionary parameter.
This method is called when a user selects a command from the text input menu. To support this, an input method must provide actions for each menu item that is placed in the menu. For example, (void)menuAction:(id)sender. Note that the sender in this instance is the info dictionary.
