Hi everyone.

I have the situation where I need to dynamically create an object based on
the value held in a string at runtime. I'm pretty sure the dynamic nature
of objective-c would allow this, but I cant seem to find the right method on
NSString or NSObject. I want to do this:


NSString* someClass = @"Dog";
Animal* anAnimal = [[someClass alloc] init];

I know this isn't right, but I'm trying to use the value held in someClass
as the name of the class I want to instantiate. thanks for the help.

Animal *anAnimal = [[NSClassFromString(someClass) alloc] init];
