Question

I have implemented filterContentForSearchText method in UISearchDisplayDelegate.

I can see that (NSString*)searchText is the text i write in the textfield, but the scope returns me NULL. What parameter do I give for scope?

Answer 1

Scope is the “area” in which you are searching, if you have implemented it. E.g.

You can then pass the relevant scope to filterContentForSearchText:scope: as follows:

[self filterContentForSearchText:searchString 
                           scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];

This was taken from Apple’s TableSearch sample code.
