Answer 1

最后这是我为此做的：

CATransition *transDown=[CATransition animation];
        [transDown setDuration:0.1];
        [transDown setType:kCATransitionPush];
        [transDown setSubtype:kCATransitionFromTop];
        [transDown setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

        [self.searchDisplayController.searchResultsTableView.layer addAnimation:transDown forKey:nil];
        [self.search.layer addAnimation:transDown forKey:nil];
