Question

I’ve been searching for this day, but I can’t find it….

Could anyone point me to a tutorial/tell me what I should do?
The documentation wasn’t really helpful…
I need this for my UITableViewController class (without a xib!)

Thanks A lot!

Answer 1

First do Gray UISearchBar w/matching scope bar programmatically

Then since the tableview and the searchtableview both use the same datasource, you have to insert an if statement in the tableview delegate methods like this:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    if (tableView == self.searchDisplayController.searchResutsTableView) {
        tableViewData = searchResultsData objectatindex...; //array with filtered data
    } else {
        tableViewData = defaultData objectatindex...; //array with unfiltered data
    }
}

Do the same for the number of rows delegate method:

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (tableView == self.searchDisplayController.searchResultsTableView) {
        return searchResultsData.count;
    } else {
        return defaultData.count;
    }
}

Then after the search text changes or search button is pressed (look at UISearchBar delegate methods), reload data to display.
