You should read some tutorials about NSDictionary . i have implemented this search on book search app where titles and authors were searched both at same time.
// for each book
NSDictionary * book = NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
title, #"TITLE", author, #"AUTHOR", nil];
[dataSource addObject:book];
after that in search method you can make changes according to your own ease
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
[tableData removeAllObjects];
if(searchText != nil && ![searchText isEqualToString:#""]){
for(NSDictionary * book in dataSource){
NSString * title = [book objectForKey:#"TITLE"];
NSString * author = [book objectForKey:#"AUTHOR"];
NSRange titleRange = [[title lowercaseString] rangeOfString:[searchText lowercaseString]];
NSRange authorRange = [[author lowercaseString] rangeOfString:[searchText lowercaseString]];
if(titleRange.location != NSNotFound || authorRange.location != NSNotFound)
[tableData addObject:book];
}
}
[tableView reloadData];
}
