I have successfully sorted the data I have by my sort key lastName
, but I want to know how to sort by lastName
, and then by firstName
. Here is the code I used to sort by lastName
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"firstName" ascending:YES];
[request setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]];
How do I add the secondary sort key of firstName
?
NSSortDescriptor *sortDescriptor1 = [[NSSortDescriptor alloc] initWithKey:@"firstName" ascending:YES];
NSSortDescriptor *sortDescriptor2 = [[NSSortDescriptor alloc] initWithKey:@"lastName" ascending:YES];
[request setSortDescriptors:[NSArray arrayWithObjects:sortDescriptor1, sortDescriptor2, nil]];
