Cocoa is right - you can't convert an NSArray to an NSDictionary just like that. Do you mean that you absolutely *have* to use an array? If so, the dictionary idea isn't going to work.

What I meant was something like this: in your object, have an instance variable like this:

NSDictionary *someDictionary;

The stuff that you want to bind your UI controls to would be in there, so that

[someDictionary valueForKey:@"someKey"]

will give you the value you want to have in the control. Then you bind the control to someDictionary.someKey, and that should do it.

Thank you for your response; But I still have a problem. I can't just have my accessor method return an NSDictionary - Cocoa expects it to be an NSArray, and I get an exception saying it can't convert the NSDictionary to the NSArray. I also tried implementing a method named:

	valueIn<Key>WithName

But it does not get called.

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.
