Question

Say I am in a myClass.m

I know I can do:

SEL aSelector = @selector(methodName);

I can latter do NSStringFromSelector(@selector(Bookmark)), for example.

Here, methodName is a selector for myClass.

Say I have a property named myProperty of type myPropertyClass and that class have a selector myPropertymethodname

How should I access it if say I want to express that selector using string.

Basically sometimes we want to use valueForKey rather than accessing the accessor directly. However, that’s prone to mistyped. I want to use NSStringFromSelector instead

SEL aSelector = @selector(myPropertyClass.myPropertymethodname);

Doesn’t work.

Answer 1

For the property’s default named getter:

SEL aSelector = @selector(myPropertymethodname);

For the property’s default named setter:

SEL aSelector = @selector(setMyPropertymethodname:);
                          ^^^^                   ^

Then just ensure the selector/property declaration is visible in the file you are compiling.

Note that a selector’s name cannot be scoped-qualified to a specific class.
