sel_registerName(_:)
Registers a method with the Objective-C runtime system, maps the method name to a selector, and returns the selector value.
Declaration
func sel_registerName(_ str: UnsafePointer<CChar>) -> SelectorParameters
- str:
A pointer to a C string. Pass the name of the method you wish to register.
Return Value
A pointer of type SEL specifying the selector for the named method.
Discussion
You must register a method name with the Objective-C runtime system to obtain the method’s selector before you can add the method to a class definition. If the method name has already been registered, this function simply returns the selector.
