Is there a way to use KVC to:
1) Given an array of EOs
2) Get an array of attribute A1 which is a double.
Not directly.
I was hoping to do:
double[] y = (double[])projects.valueForKeyPath
("calculatedRewardScore");
but this throws an exception.
What am I doing wrong?
valueForKey (and valueForKeyPath) on an NSArray return an NSArray
(unless using an aggregate function like @sum, in which case they
return a Double IIRC). What you want is (warning, untested code):
double[] y = (double[])((NSArray)projects.valueForKeyPath
("calculatedRewardScore")).objects();
