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
