NSString *searchString = @"subcat"
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Cate = %@",searchString];
NSArray *array = [yourArray filteredArrayUsingPredicate:predicate];
if (array.count > 0)
{
// here goes your code
}

Using Linq to ObjectiveC you can filter it as follows:

NSArray* itemsInCategory = [menuArr where:^BOOL(id dic) {
    return [[dic objectForKey:@"Cate"] isEqualToString:@"subcat"];
}];

This finds all the dictionaries where Cate=subcat.

Use NSPredicate

NSArray *filtered = [yourArray filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(Cate LIKE[CD] %@)", @"subcat"]];
