问题 I have a table view with a search bar in the tableHeaderView , managed by a UISearchController . I use the standard UISearchController presentation animation. I want to animate another view with the same duration as the searchBar animation. I tried various duration values but alas they don't match perfectly at all times.

问题 I want to build a search control like the maps app; the search opens a result tableview (which works fine) on iPhone and should open a tableview in a popover on iPad. This used to be automatic in UISearchDisplayController but does not work anymore and it shows a fullscreen tableview on iPad. self.resultsController = [[EFResultTableViewController alloc] init]; [self.resultsController.tableView setDelegate:(id<UITableViewDelegate>)self]; self.searchController = [[UISearchController alloc]
