Basically, I am want to filter the results of what is brought in by the NSXMLParser into search terms as they are typed into a search bar.
Any help is much appreciated from you guys/gals.

Answer 1

Do this
Store the value get from parser into an array. responseArray
Use another array to store the value to show in table
datasourceArray
After webvservice recieve successful response datasourceArray=responseArray then reload table with [tableView reloadData]
When search starts,search from responseArray load the result into DatasourceArray then call reloadData again

Answer 2

you can use textFeildDidBegunEditingdelegate method of uitextFeild
then this code will help you filter
NSMutableArray *array1=(NSMutableArray*)[txtEditFavoriteColor.text componentsSeparatedByString:#" "];//words from textFeild
for (NSString *str in array1)
{
NSString *tempStr = [str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if([tempStr length])
{
[arryOfWordsToBeSearched addObject:tempStr];
}
}
NSMutableArray *subpredicates = [NSMutableArray array];
for(NSString *term in arryOfWordsToBeSearched) {
NSPredicate *p = [NSPredicate predicateWithFormat:#"name contains[cd] %#",term];
[subpredicates addObject:p];
}
NSPredicate *filter = [NSCompoundPredicate andPredicateWithSubpredicates:subpredicates];
//***************************************************************predicate made above******
result = [[NSMutableArray alloc]initWithArray:[arryOfDummyData filteredArrayUsingPredicate: filter]];//search on data array using predicate

Create table view controller subclass with nibfile. Add search bar to nibfile at top of table view. Then search result view controller will be added automatically.
most of the property of searchResultViewController like delegate, searchBar ,searchDisplayDatasource and delegate are automatically set. and also for search bar delegate is set as file owner.
Now implement table view conform to this protocol . .
Implement the following delegate method .
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
// create the array of ur search result object
}
now implementing tableViewDataSource and delegate check which table is calling method
as follows
if (tableView == self.searchDisplayController.searchResultsTableView)
{
// searchResultsTableView
}
else
{
// main table view
}
implement the corresponding code.
