I have read several of the post about Objective-C method syntax but I guess I don’t understand multiple names for a method. I’m trying to create a method called getBusStops with NSString and NSTimeInterval parameters and a return type of NSMutableArray. This is how I have constructed the method but it obviously gets errors at … Read more

I have several private “helper” methods inside the class that do not require access to any of the class members, and operate solely on their arguments, returning a result. public class Example { private Something member; public double compute() { double total = 0; total … Read more
