... and it goes without saying that if the method in question takes a parameter, its signature is drawRect:, not drawRect.

Is it possible to call a method at runtime when all my app knows is a string of the method?
For example object A has a string called "drawRect" and a rectangle called myDrawRect
Then I want object B to perform drawRect with myDrawRect as it's parameter.
So it would be something like [objectB doMethod:@"drawRect" withParameter:myDrawRect];

[objectB performSelector:NSSelectorFromString(@"drawRect") withObject:myDrawRect];

of course it's better to do this:

[objectB drawRect:myDrawRect];
