Objective-C Access @private instance variables from another class

I've been looking at this question and came across the following code in one of the answers

@interface MyClass : NSObject
{
    @private
    int someVar;  // Can only be accessed by instances of MyClass

    @public
    int aPublicVar;  // Can be accessed by any object
}
@end

Is there anyway to access someVar from any other class (including derived classes)?

As with most dynamic languages you can get at this information in Objective C, however, it is painful. Look here for an example.

No. That's exactly what @private means. The compiler explicitly disallows any other class (even subclasses) from accessing that ivar.

@public means anyone can access the ivar, and @protected means subclasses can access it but other classes can't.
