That feels a bit dirty to me. I'd recommend using a protocol instead. As long
as the compiler has seen the method *somewhere*, it will consider it

To be extra fail-safe, you might want to perform a cast to be sure the right

You need to #import a header file with an @interface declaration
for the 'initWithManager:' method.
The rule is that when the compiler sees a message send to a
receiver of type 'id' (which is the return type of 'alloc'), it
needs to have seen *some

to avoid the warning or otherwise fix it?
You could try declaring initWithManager: in a category on the class
visible only to your implementation code. (i.e. at the top of
your .m file)
The class name is passed in as a string and the class is formed from

Off-topic: instead of using the Obj-C runtime’s C API, you can
express this as
if ([myClass
myObj = [[myClass alloc] performSelector(@selector(initWithManager:)
withObject:self];
Would this work?
You could do :
id myObj =[myClass alloc];
myObj = [myObj performSelector(@selector(initWithManager:) withObject:myObj];

That's wont help because myClass is a variable created from a String.
But it will help, because Quincey's suggestion is not contingent on the type of

What warning do you get? (Its not obvious from context).
