Yes:
http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/nsmutablearray_Class/Reference/Reference.html
"NSArray and NSMutableArray are part of a class cluster, so arrays are
not actual instances of the NSArray or NSMutableArray classes but of
one of their private subclasses."
Subclassing is fraught with many angry, fire-breathing, treasure-
grubbing dragons and as such is *not* recommended. Especially if
you're only trying to get a mutable array populated with a single
object.
What's wrong with [[NSMutableArray arrayWithObject:[[MyClass alloc]
init]]; ?
Create a convenience method somewhere in your project such as -
mutableArrayWithMyClass that contains the above and you're done. No
dragons.
