If you want to filter array take a look on this code:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name == %@", @"qwe"];
NSArray *result = [self.categoryItems filteredArrayUsingPredicate:predicate];

But if you want to sort array take a look on the following functions:

- (NSArray *)sortedArrayUsingFunction:(NSInteger (*)(id, id, void *))comparator context:(void *)context;
- (NSArray *)sortedArrayUsingFunction:(NSInteger (*)(id, id, void *))comparator context:(void *)context hint:(NSData *)hint;
- (NSArray *)sortedArrayUsingSelector:(SEL)comparator;
