UISearchBar with UISearchDisplayController animates outside screen - ios

Question

I have standard iPad view controller which has a custom navigation bar at the top. In the xib-file I've added a UISearchBar aligned to the right edge of the view. The search bar is 320px in width. I init a searchdisplaycontroller like this:
// Search display controller
self.mySearchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:_searchBar
contentsController:self];
_mySearchDisplayController.delegate = self;
_mySearchDisplayController.searchResultsDataSource = self;
_mySearchDisplayController.searchResultsDelegate = self;
The problem is that when I press the search bar, the bar resizes to be the full width of the entire view, but keeps its x-position. This means that it stretches far outside the screen. I'm guessing it has something to do with the "Cancel" button that slides in next to a search bar. If I place the search bar to the far left in the screen, it animates to the full width of the screen and the cancel button is visible.
Anyone has a solution for this?

You can animate the frame of your UISearchBar in the searchDisplayControllerWillBeginSearch method to correct its position like this:
- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
// animate the search bar to the left ie. x=0
[UIView animateWithDuration:0.25f animations:^{
CGRect frame = controller.searchBar.frame;
frame.origin.x = 0;
controller.searchBar.frame = frame;
}];
// remove all toolbar items if you need to
[self.toolbar setItems:nil animated:YES];
}
and the animate it back again when finished searching:
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
// animate search bar back to its previous position and size
// in my case it was x=55, y=1
// and reduce its width by the amount moved, again 55px
[UIView animateWithDuration:0.25f
delay:0.0f
// the UIViewAnimationOptionLayoutSubviews is IMPORTANT,
// otherwise you get no animation
// but some kind of snap-back movement
options:UIViewAnimationOptionLayoutSubviews
animations:^{
CGRect frame = self.toolbar.frame;
frame.origin.y = 1;
frame.origin.x = 55;
frame.size.width -= 55;
controller.searchBar.frame = frame;
}
completion:^(BOOL finished){
// when finished, insert any tool bar items you had
[self.toolbar setItems:[NSArray arrayWithObjects: /* put your bar button items here */] animated:YES];
}];
}
I have answered a similar question, you can check it here, I've put some images too.
The only thing you have to do is to adapt the code for the iPad.
