UISearchBar in UINavigationBar can't add UIBarButtonItem

问题

I'm trying to add a UISearchBar to a UINavigationbar using self.searchDisplayController.displaysSearchBarInNavigationBar = YES;

The UISearchBar gets added quite well into the UINavigationBar, but the left/right UIBarButtons are gone. I just can't figure out how to add them.

Andy ideas or examples on this?

回答1:

Dumb error from mine. When using self.searchDisplayController.displaysSearchBarInNavigationBar = YES; You need to use self.searchDisplayController.navigationItem to add the UIBarButtons. Now it is working properly.

For others viewing this thread, elaborating Ben's answer is what worked for me. [self.searchDisplayController.navigationItem setLeftBarButtonItem: self.sidebarButton];
