Question

Is there a way to call [anObject performSelector]; with more than 2 objects? I know you can use an array to pass multiple arguments, but I was wondering if there was a lower level way to call a function I already have defined with more that 2 arguments without using a helper function with an nsarray of arguments.

Answer 1

Either (1) Use an NSInvocation or (2) directly use objc_msgSend.

objc_msgSend(target, @selector(action:::), arg1, arg2, arg3);

(Note: make sure all arguments are id‘s, otherwise the arguments might not be sent correctly.)
