Question

I have a NSArray of objects. Each object has several properties.

For example:
The NSArray oneArray has 5 objects. Each object has the following properties: name, address, ZIP_Code.

How can I sort the NSArray, by name?

Answer 1

NSSortDescriptor* dx = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES];
NSSortDescriptor* dy = [[NSSortDescriptor alloc] initWithKey:@"address" ascending:NO selector:@selector(caseInsensitiveCompare:)];
[arr sortUsingDescriptors:[NSArray arrayWithObjects:dx, dy, nil]];
[dx release];
[dy release];

Taken from code posted by KennyTM. Edited by Jordan to actually work 😉 Replace Array arr with your array. Modify to suit.
