Hello again,

In C/C++ and the .NET languages I am used to, I have generally tried to prefix any member variables inside class methods with "this"

i.e. this.m_sMyString = "this is my string";

In Objective-C, this doesn't seem as clear to me (or at least it doesn't compile). For example:

- (id)initWithString:(NSString *) string {
    self.myString = [[NSString alloc] initWithString:string];
}

Produces an error:

error: request for member 'myString' in something not a structure or union

I am sure this is something very simple and basic I am missing, but any assistance is appreciated.

The short answer is: self is a pointer.

The longer answer is a question: Why do you do this? Do your naming conventions not make clear that something is an instance variable?
