Several things:
1 - Using the dot syntax (a feature of Objective-C 2.0) requires that
you have proper accessors set up for the property you're using. In
this case, the "myString" property. Do you?
2 - In your -initWithString: method, you probably want:
self.myString = string;
... in your version, you're uselessly creating a string from the
passed string when the passed string will do. If you waned a copy of
the passed string, the property is where you'd specify this behavior
(ie, copy versus retain, etc.).
