Can I overload an operator in Objective-C?

Question

Is it possible to override operator use in Objective-C?

For example

myClassInstance + myClassInstance

calls a custom function to ad

Answer 1

First, operator overloading is evil. Second, C doesn't have operator overloading, and Objective-C is a proper superset of C, which only adds a handful of keywords and a messaging syntax.

That being said, if you're using Apple's development environment, you can use Objective-C++ instead of Objective-C, which gives you access to all of C++'s mistakes and misfeatures, including operator overloading. The simplest way to use Objective-C++ is just to change the extension on your implementation files from ".m" to ".mm"
