UISearchDisplayController, what's the reference to the UITableView ? - iphone

Question

If I have multiple UITableViews, and a UISearchBar with UISearchDisplayController, in the UITableView delegate and datasource methods, how do I get a reference to the UITableView for the Search? Thanks.

Answer 1

get a reference to your UISearchDisplayController either via an outlet connected to your NIB file or when you create the searchBar programmatically. Once you have the reference, in all of your datasource and delegate methods you can just check to see which tableView is being passed and act appropriately. For example:
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (aTableView==self.searchDisplayController.searchResultsTableView) {
// do something with the search data source
self.searchDisplayController.active=NO;
}else{
// do something with the regular data Source
}
// present a view or other response to the selected row
}
here is how you might create the search bar and get the reference to the UISearchDisplayController
-(UISearchBar *)searchBar{
// Create a search bar
if (searchBar==nil){
UISearchBar *aSearchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)] autorelease];
aSearchBar.autocorrectionType = UITextAutocorrectionTypeNo;
aSearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
aSearchBar.keyboardType = UIKeyboardTypeAlphabet;
aSearchBar.barStyle=UIBarStyleBlack;
self.searchBar=aSearchBar;
// Create the search display controller
UISearchDisplayController *aSearchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self] ;
aSearchDisplayController.searchResultsDataSource = self;
aSearchDisplayController.searchResultsDelegate = self;
aSearchDisplayController.delegate=self;
self.searchDisplayController=aSearchDisplayController;
[aSearchDisplayController release];
}
return searchBar;
}
then add it to your tableView like this:
self.tableView.tableHeaderView = self.searchBar;
Good luck
