the compiler is complaining just because they all have the same name
and he is confused about witch to choose....
to resolve the issue, just rename the parameters of your procedure.
IE: - (id)initWithLabel:(NSString *)initLabel pin:(NSString *)initPin
seed:(NSString *)initSeed {
or whatever name that makes them different than your classe's
definition.

I am trying to define a pure data object in Cocoa. This object
doesn't do anything, it should just act as a container for three
strings. This is generally a good design pattern, at least in Java.
In Cocoa, I am running into a lot of resistance. The constructor is
rather complicated.
And the compiler complains about this:
- (id)initWithLabel:(NSString *)label pin:(NSString *)pin seed:
(NSString *)seed {
if (self = [super init]) {
self.label = label; ///<----------- compiler complains
self.pin = pin;
self.seed = seed;
}
return self;
}
I get three warnings that say "local declaration of x overrides
instance variables. I thought I could differentiate between the
parameters and the instance variables using self.variable vs just
variable.
What's the Cocoa way of doing this? Do I really have to name the
parameters pLabel, pSeed, and pPin? Or would it be better to just
keep that stuff in a Dictionary object?
Thanks for any help,
Nik
