Hi,
I have a short list with "Name" and "Surname" fields.
I want to sort this list by "Surname".
How should I build the NSArray?
How should I use the NSArray methods?
Thank you.
Download my Open Source BDControl framework from
<
http://bdistributed.com/Projects/BDControl/>.
Then use the following to sort the mutable array "myArray":
BDSortOrdering *surnameOrdering;
NSArray *sortOrderings;
surnameOrdering = [BDSortOrdering sortOrderingWithKey:@"surname"
selector:BDCompareCaseInsensitiveAscending];
sortOrderings = [NSArray arrayWithObjects:surnameOrdering, nil];
[myArray sortUsingKeyOrderArray:sortOrderings];
If you want, you can sort by surname and then by name, by using this code:
BDSortOrdering *surnameOrdering;
BDSortOrdering *nameOrdering;
NSArray *sortOrderings;
surnameOrdering = [BDSortOrdering sortOrderingWithKey:@"surname"
selector:BDCompareCaseInsensitiveAscending];
surnameOrdering = [BDSortOrdering sortOrderingWithKey:@"name"
selector:BDCompareCaseInsensitiveAscending];
sortOrderings = [NSArray arrayWithObjects:surnameOrdering,
nameOrdering, nil];
[myArray sortUsingKeyOrderArray:sortOrderings];
(I assume that the attributes of the objects in your array are
actually named "name" and "surname" so they'll work properly with
Key-Value Coding.)
The documentation for the BDSortOrdering class is online at
<
http://bdistributed.com/projects/BDControl/Documentation/Classes/BDSortOrdering.html>.
The BDControl framework will make your life as a Cocoa developer
easier, and it's available under a BSD-style license.
