Question

I’m developing a library to IOS, which at some point need to create a NSArray of methods reference´s from various classes. To an single class that will at some point call them.

Any ideas how to do that??

Thanks

Answer 1

You have some options. You can use NSStrings to actually have the name of your methods and then just do:

NSString *myMethodName = @"hellWorld";
SEL selector = selectorFromString(myMethodName);

You can then add your selector to your NSArray.

You can also use NSInvocations and store the methods and define the target later:

An NSInvocation object contains all the elements of an Objective-C
message: a target, a selector, arguments, and the return value. Each
of these elements can be set directly, and the return value is set
automatically when the NSInvocation object is dispatched.

From Apple Documentation.

Edit 1 (for the fun of it):

- (Method *)getMethodsPointer{
    unsigned int number = 0;

    Method *myMethods = class_copyMethodList([self class], &number);

    //for(int i=0;i<number;i++)
    // {
    //    printf("%s",sel_getName(method_getName(myMethods[i])));
    //}
    return myMethods;
}
