推送另一个视图控制器后 searchBar 不隐藏

Question

我在表格的标题视图中创建了一个搜索栏：

self.searchResults = [NSMutableArray arrayWithCapacity:[self.list count]];
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.searchBar.barTintColor = [UIColor clearColor];
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);
[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor whiteColor]];
[self.searchController.searchBar becomeFirstResponder];

并且当点击 tableview 中的某一行时，将推送一个新的视图控制器。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    NSLog(@"HEY ROW %ld", indexPath.row+1);
    ZLContainerViewController *controller = [[ZLContainerViewController alloc]init]; // a container for UIPage
    [self.navigationController pushViewController:controller animated:YES];    
}

但是，在推送新的视图控制器后，搜索栏仍然存在。我该如何解决这个问题？

非常感谢任何建议！

Answer 1

在viewDidLoad中使用下面的代码。

斯威夫特：

self.definesPresentationContext = true

目标-C：

self.definesPresentationContext = YES;

这解决了我的问题。

这两个 UISearchBarDelegate 委托方法之一应该可以解决您的问题

- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
return YES;
}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
[self.searchBar resignFirstResponder];
}
