无法停止动画并隐藏searchController的searchBar上的取消按钮

Question

我在navigationBar中设置了searchBar。激活后，它会动画并出现取消按钮。我试图停止动画并阻止取消按钮出现。我的故事板是一个在navigationController中设置的tableviewController。

self.searchController = [[UISearchController alloc]initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.hidesNavigationBarDuringPresentation = NO;

self.searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y, self.searchController.searchBar.frame.size.width, 44.0);

self.navigationItem.titleView = self.searchController.searchBar;
[self.searchController.searchBar setShowsCancelButton:NO animated:NO];

Answer 1

尝试[self.searchController.searchBar showsCancelButton:NO]。
