Swift 到 Objective-C 的语法

Question

有人能帮我把这行代码转换成 Objective-C 吗？ 它是用 Swift 编写的，我对语法不太熟悉。

searchController = UISearchController(searchResultsController: nil)
searchController.hidesNavigationBarDuringPresentation = false
self.searchController.searchBar.delegate = self
presentViewController(searchController, animated: true, completion: nil)

Answer 1

如果 self 是 UIViewController

[self presentViewController:searchController animated:YES completion:nil];

Answer 2

[self presentViewController:searchController animated:YES completion:nil];
