– You can have heterogeneous collections (impossible in C++) and use them without downcasting (something you need to do in Java). Great flexibility when dealing with existing frameworks or Cocoa itself. This is one of the more useful feature of Objective-C.
– You can add methods to a class for which you don’t have the source code. > I’d be interested to know what constraints C++ or Java hope that answers some of your questions. these are just a FEW of the things you can do in obj-c that neither c++ nor java support. h file, then #importing it to your source instantly gives you access to these new methods you just added to the base foundation. well, you can simply add that NSArray (Reverse) NSArray (the foundation array type) has a sort method, but it has no reverseSort method. Obj-c also lets you add methods dynamicly to already existing classes. even java doesn’t allow you this sort of flexibility. this allows you to do some highly dynamic programming. This is perfectly legal in obj-c because of the way messaging passing works. say you have two interfaces, one for printing and one for drawing, you can do typechecking on these to using the type id varName so now varName accepts objects that confrom to those two interfaces (or protocols in objc).Īnother thing that c++ doesn’t let you do is “blind message calling” say i have a method named print in two objects. the id type has other useful features like multi-type checking at once. templates are a fancy macro, and i don’t think fancy macros are a good solution when you’re attempting to do object oriented programming. so writing functions that take multiple types doesn’t mean you have to write root interfaces for two classes, and you don’t have to make your own custom base object type for the entire project (which isn’t advisable anyways in c++). objective-c has a root type, id, unlike C++. You could also check Gorm, the GNUstep equivalent of IB.Įasy. Yet you still has all the power of normal programming - it’s not dumbed down programming, it actually HELP you and save you time. Plus, InterfaceBuilder is an incredible RAD tool - you aren’t that far from a pure designing click-and-run programming. The less code, the faster you program, the less bug you have. You rarely inherits widgets in Cocoa - and that’s a good thing. Basically, the idea is to use the existing code, not to force developers to inherits some widgets (tables.) for their need. It doesn’t do your laundry, but it’s not far - the whole idea of OpenStep frameworks was to let you fit your program “in” the framework.

It was good on OPENSTEP, it’s still damn good on Mac computers now. The fact that it runs on OSX is irrelevant - that’s not why it is good. The single fact that Apple didn’t updated it much since 1994 should speak for itself (they mostly added widgets). It’s much better than most of the OO framework, because it heavily uses many design patterns such as delegation, composition, mvc, etc.Ĭheck things like the responder chain … or NSTableView delegate … Sorry for this inconvenience.Honnestly, it’s because you didn’t developed with it.
This is an Embarcadero's decision, not ours. Starter Edition has many limitations and some RAD & Installer features are disabled in this edition.
