Cannot get UISearchBar Scope Bar to appear in Toolbar (or anywhere) on iPad
- by Jann
This is really causing me fits. I see a lot of info on putting a UISearchBar in the top row of a UITableView -- but I am putting the UISearchBar into the Toolbar at the top of my screen (on the iPad). I cannot find ANYTHING regarding how to handle UISearchBar and UISearchDisplayController using a UIPopoverController on the iPad. Any more info about the UISearchDisplayController using a UIPopoverController would be greatly appreciated. Please help with this as I am at my wit's end.
Using IB, I put a toolbar on the IUView on the iPad. I added the following: Search Bar (not Search Bar and Search Display) to the toolbar. I set the options to be as follows: Show Cancel Button, Show Scope Bar, Scope Button Titles are: "Title1" and "Title2" (with Title2's radio button selected). Opaque, Clear Context and Auto Resize are checked. I hooked up the delegate of Search Bar to the "File's Owner" and linked it to IBOutlet theSearchBar.
In my viewWillAppear I have the following:
//Just in case:
[theSearchBar setScopeButtonTitles:[NSArray arrayWithObjects:@"Near Me",@"Everywhere",nil]];
//Just in case (again):
[theSearchBar setShowsScopeBar:YES];
//doesn't seem to do anything:
//[theSearchBar sizeToFit];
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:theSearchBar contentsController:self];
[self setSearchDisplayController:searchDisplayController];
[searchDisplayController setDelegate:self];
[searchDisplayController setSearchResultsDataSource:self];
//again--does not seem to do anything..but people have suggested it:
[theSearchBar sizeToFit];
Okay, so far, I thought, so good. So, I made the File's Owner .m file to be a delegate for: UISearchBarDelegate, UISearchDisplayDelegate.
My issue: I have yet to implement the delegates necessary to do the search but still... shouldn't I be seeing the scopeBar next to the search field when I click into the search field? Just so you know I DO see the log of the characters I type, so the delegate is working.
I have the following dummy functions in the .m file (just in case)
// called when keyboard search button pressed
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
NSLog(@"Search Button Clicked\n");
[theSearchBar resignFirstResponder];
}
// called when cancel button pressed
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
NSLog(@"Cancel Button Clicked\n");
[theSearchBar resignFirstResponder];
}
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
NSLog(@"Search Text So Far: '%@'\n",searchText);
}
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
return YES;
}
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
return YES;
}
Why doesn't the Scope Bar appear? A results UIPopoverController appears with the title "Results" and "No results found" (of course) when i type the first character in my search...but no scope bar. (not that i expect anything other than "No Results Found".
I am wondering where the scope bar is supposed to appear...in the titleView of the UIPopover? In the toolbar to the right of the search area? Where?
