Ok, this bugged me for the a couple of hours, but I finally got it to work! The problem seems to be that the UISearchDisplayController keeps track of whether or not it has hid the navigation bar, and if it has, it restore it, after the view has been dismissed. That is why with many of the answers above you see the tail end of the animation of the bar hiding itself when the new view is pushed. However, by tricking the search display controller we can change this behavior.
First: Subclass The UISearchDisplayController
Following the answer on how to keep a navigation controller from hiding, found here, I altered the code, to keep the navigation bar hidden:
- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
if(self.active == visible)
return;
[self.searchContentsController.navigationController setNavigationBarHidden:YES animated:YES];
[super setActive:visible animated:animated];
if (visible)
[self.searchBar becomeFirstResponder];
else{
[self.searchBar resignFirstResponder];
[self.searchContentsController.navigationController setNavigationBarHidden:NO animated:YES];
}
}
Note we hide the navbar before we call the super setActive function. This seems to keep the super class from trying to hide the nav bar and consequently, from trying to restore it ater item selection. Now when the controller becomes active, the bar will be hidden like normal. Also note that we restore the navigation bar when the searchBar resigns first responder. This will restore the bar if we cancel out of the controller.
Second: Hide Navigation Bar When Exiting
If we hide the navigation bar in the view will disappear, it will be hidden:
-(void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}
Third: Hide Navigation Bar When Returning
The only problem now is that if we select a row from the filtered tableview, when we return, the navigation bar will be visible. To fix this we need to put a check in view will Appear:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if(self.isFiltered){
[self.navigationController setNavigationBarHidden:YES animated:NO];
}
}
While this feels like a huge hack, it does the trick and I could see no better way of doing it.
