Question

I have searched but all the questions talk about sorting NSStrings.

I have a NSMutableArray with objects (myvector) which have an attribute NSDecimalNumber called fitness.

I want to filter all the object which attribute fitness is equal or grater than a ‘k’ value.

Answer 1

You have to use NSPredicate. I just assumed the value of k to be 2.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"fitness>=2.0"];
NSArray *arr = [data filteredArrayUsingPredicate:predicate];
