I am trying to modify the array controller programmatically and I'm
running
into problems using mutableArrayForKeyValue
I am using this line
id proxy = [controller mutableArrayValueForKey:@"Person"];
when I do
[proxy addObject:newPerson]
I get
[<NSArrayController 0x130050> valueForUndefinedKey:]: this class is
not key
value coding-compliant for the key Person.
In IB I have bound the Content Array to my array member in App
Controller.
Shouldn't this work?
No.
Just as the error states, @"Person" is not a valid key for the
controller.
I have set the class name to be of the "Person" class. Right now the
key I
am using is "Person" but I have also tried "array" and got the same
problem.
Similarly, @"array" is not a valid key for the controller.
What do I do next?
Look at the API reference for NSArrayController to see what are valid
messages to send to the controller to achieve what it is that you
want; read the bindings conceptual documentation to see how else you
might achieve this by modifying the source data controller; or look at
the myriad online examples that illustrate this.
