Best way to sort an NSArray of NSDictionary objects?
Use NSSortDescriptor like this..
NSSortDescriptor * descriptor = [[NSSortDescriptor alloc] initWithKey:@"interest" ascending:YES];stories = [stories sortedArrayUsingDescriptors:@[descriptor]];recent = [stories copy];stories is the array you want to sort. recent is another mutable array which has sorted dictionary values. Change the @"interest" with the key value on which you have to sort.
All the best
[array sortUsingDescriptors:[NSArray arrayWithObjects:[NSSortDescriptor sortDescriptorWithKey:@"YOUR-KEY" ascending:YES], nil]];I don't really want to break it into multiple lines. It's already simple enough for me.
You can just traverse from the parent to the required child property. For e.g.
NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"parent.child.child" ascending:YES];
