Question

我有一个UIPopoverController，其中包含UITableViewController。另外，我正在使用UISearchDisplayController。我的类界面是这样的：

@interface SearchController : UITableViewController <UITableViewDataSource, UITableViewDelegate, UIPopoverControllerDelegate, UISearchDisplayDelegate, UISearchBarDelegate> {

UISearchBar *_searchBar;
UISearchDisplayController *_searchDisplayVC;
}

我的init看起来像这样：

//create a search bar
_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
_searchBar.delegate = self;

_searchDisplayVC = [[UISearchDisplayController alloc] initWithSearchBar:_searchBar contentsController:self];

self.searchDisplayController.delegate = self;
self.searchDisplayController.searchResultsDataSource = self;
self.searchDisplayController.searchResultsDelegate = self;

// add a searchbar
self.tableView.tableHeaderView = _searchBar;

我的问题是，当我选择搜索栏在其中输入搜索词组时，即使尝试这样做，键盘也不会被忽略：

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

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
    NSLog(@"Dismiss popover controller");
    [_searchBar becomeFirstResponder];
    [_searchBar resignFirstResponder];
}

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar {
    //trying to resolve the issue with not working automatic hiding of a keyboard.
    [searchBar resignFirstResponder];
    [searchBar endEditing:YES];
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
    [TableSearchViewController dismissKeyboard];
}

-(BOOL)disablesAutomaticKeyboardDismissal {
    return NO;
}

+ (void)dismissKeyboard {
    [[[[UIApplication sharedApplication] delegate] window] endEditing:YES];
}

任何人都知道如何解雇键盘？

我找到了解决这个问题的方法。在父视图控制器中，我已将名为UIViewController的{{1}}方法覆盖为：

disablesAutomaticKeyboardDismissal

它工作正常！ :)键盘按预期隐藏。感谢@ujell对此问题感兴趣：）

在UIPopover中使用UISearchBar的UISearchDisplayController消除了键盘问题
