For short array by a key.. Like Name....Put the key on which you want to short your array

This will Short your array Ascending

 NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"Your Key"  ascending:YES  selector:@selector(localizedStandardCompare:)];
 NSArray *shortedArray=[Your array sortedArrayUsingDescriptors:[NSArray arrayWithObjects:descriptor,nil]];

This will Short your array Decending

 NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"Your Key"  ascending:NO  selector:@selector(localizedStandardCompare:)];
 NSArray *shortedArray=[Your array sortedArrayUsingDescriptors:[NSArray arrayWithObjects:descriptor,nil]];
