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];
}
Hey Matt -
If you prefer this type of explicit reference to an instance variable,
this syntax will work:
self->myString = [[NSString alloc] initWithString:string];
Since self is a pointer, you need to use the -> operator. If you're
familiar with working with structure members, object members work the
same way. The . syntax only applies if you have an actual object
instead of a pointer to an object, which you'll really never have in
objective-c.
Good Luck -

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.
Thanks,
Matt
