ios - 激活 UISearchBar

Question

我试图加载一个 View ，就像用户已经按下 UISearchBar 一样。我希望 SearchController 加载顶部的 UISearchBar 以及取消按钮。

我已经试过了:

func activateSearch(){
        self.searchBarShouldBeginEditing(self.searchController.searchBar)
        self.willPresentSearchController(self.searchController)
        self.updateSearchResultsForSearchController(self.searchController)
}

Answer 1

func activateSearch() {
    self.searchController.isActive = true 
    self.searchController.searchBar.isHidden = false
    self.searchController.searchBar.becomeFirstResponder()
 }
