UIPopoverController 中的 UISearchBar 没有得到第一响应者

Question

当用户按下搜索栏按钮时，会出现一个带有搜索栏的弹出框。我正在从仅包含 tableview 的 nib 加载搜索结果视图。现在，我希望在弹出窗口出现时选择搜索栏，但是搜索栏没有得到第一响应者。我尝试在didPresentSearchController: 委托方法中设置它，但这也不起作用。以下是我尝试过的代码。

- (IBAction)search:(id)sender {
    self.searchView = [[[NSBundle mainBundle] loadNibNamed:@"Popover" owner:self options:nil] objectAtIndex:0];

    self.searchController = [[UISearchController alloc] initWithSearchResultsController:self.searchView];
    self.searchController.searchBar.scopeButtonTitles = @[@"BLARGH", @"WARGH"];
    self.searchController.searchBar.selectedScopeButtonIndex = 1;
    self.searchController.searchBar.delegate = self;
    self.searchController.delegate = self;

    self.table.delegate = self;
    self.table.dataSource = self;
    self.table.tableHeaderView = self.searchController.searchBar;

    self.popover = [[UIPopoverController alloc] initWithContentViewController:self.searchView];

    [self.popover setPopoverContentSize:CGSizeMake(320, 88)];
    self.popover.delegate = self;

    [self.popover presentPopoverFromBarButtonItem:self.searchButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    [self.searchController.searchBar becomeFirstResponder];
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
    [self.popover setPopoverContentSize:CGSizeMake(320, 600)];
    self.table.frame = CGRectMake(0, 0, 320, 600);
    NSLog(@"Me pressed");
}

我认为它对你有帮助 使用此委托并检查您是否已连接搜索栏委托的 .xib 或情节提要

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