call class method within a framework

In objective-c how can i call class method inside a framework?

This is the method declaration:

public class func setGameLevel(level:Int)
{
    current_level = level
}

That is the class declaration (of the framework class):

public class MyClass
{

I imported the framework, now how can i call the method setGameLevel of the MyClass method?

In swift its called using:

MyClass.setGameLevel(1)
