Hi everyone!

I need to convert a custom object to a different object. How can I do that?

I know that typecasting doesn't work (the only thing is does is "shuts the compiler warnings off", but nothing more). Here is a sample code:

MyType* obj1;
MyOtherType* obj2;

obj1 = [MyType initWithData: 1];
obj2 = (MyOtherType*) obj1;

if ([obj2 isMemberOfClass: [MyOtherType class]]) { NSLog(@"OK"); }
else if ([obj2 isMemberOfClass: [MyType class]]) { NSLog(@"Nope"); }

The result is:

Nope

What can I do??
