- objc:add-method CLASS METHOD TYPES PROCprocedure
- objc:add-class-method CLASS METHOD TYPES PROCprocedure
Adds a class or instance method to CLASS.
METHOD Method name as a string (e.g. "setWidth:height:") TYPES List of encoded argument type strings (such as objc:INT or "@"). PROC Scheme procedure representing the method.
The structure of the TYPES list is (RETURN-TYPE SELF SELECTOR METHOD-ARGS...).
You may add Scheme methods to pure Objective C classes; when class proxies are enabled, this will automatically taint the class so that safe calls are used. Currently, a warning is printed when a class is tainted.
