You might be better off with an NSDictionary for this. NSArray
doesn't support what you're trying to do.

Hi everyone; I'm fairly new to KVC. I have my application working
fabulously with my data model. Parameters and sliders and text
field's values, min, and max are bound to my objective c object.
Parameter validation works great.
However now I want to make an static array of values - each element
bound to a different gui control.
What key path do I use to specify the n'th NSNumber in a
NSMutableArray? I tried the following:
myData.params.2
myData.params.@2
myData.params@2
And then what is the best way to implement the methods in my object
to allow for this?
Or do I have to split them all out of the array and have separate
methods for each item like:
- (void) setParams0: (NSNumber *);
- (void) setParams1 : (NSNumber *);
- (void) setParams2 : (NSNumber *);
- (NSNumber *) getParams0;
- (NSNumber *) getParams1;
- (NSNumber *) getParams2;
etc...? I can't imagine I must resort to this..
All the examples I find for KVC and arrays are assuming that the
array is something to be filled in by the user with dynamic number
of items, for table views etc.
