在iPhone上的联系人应用程序中输入搜索词,然后点击"搜索"按钮,键盘被隐藏,但取消按钮仍然启用.在我的应用程序中,当我调用resignFirstResponder时取消按钮被禁用.

任何人都知道如何在取消按钮处于启用状态的同时隐藏键盘？

我使用以下代码:

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

键盘滑出视图,但搜索文本字段右侧的"取消"按钮被禁用,因此我无法取消搜索.联系人应用程序将取消按钮维持在启用状态.

我想也许一个解决方案是深入到searchBar对象并在实际文本字段上调用resignFirstResponder,而不是搜索栏本身.

任何输入赞赏.

我的应用程序有一个搜索栏,用于从表视图中搜索记录,该视图由sqlite DB填充.我的问题是,当视图打开时,"取消"按钮未启用,我也无法触及,就像只有图像一样.它就在那里,但没有动作.当我们点击该搜索栏文本时,取消按钮将更改为"已完成",它将启用一个.所以这是我的代码

这是我的搜索栏视图,看到取消按钮.它没有启用

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
    //[newSearchBar setShowsCancelButton:YES animated:YES];


    newSearchBar.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters;

    NSLog(@"search begin edit") ;

    //searchString = searchBar.text;

    //NSLog(@"print did edit searchstring : %@", searchString) ;

    for(UIView *view in [searchBar subviews])       
    {

        //shareItemId =newSearchBar.text;

        if([view isKindOfClass:[NSClassFromString(@"UINavigationButton") class]]) {
            [(UIBarItem *)view setTitle:@"Done"];

        }
        }

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
    NSLog(@"searchBarTextDidEndEditing:");


    [searchBar resignFirstResponder];
    //[self dismissModalViewControllerAnimated:YES];
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
    NSLog(@"searchBarSearchButtonClicked");


    searchString = searchBar.text;
    NSLog(@"search %@", searchBar.text);
    [newSearchBar setShowsCancelButton:NO animated:YES];

    [searchBar resignFirstResponder];
    //[self dismissModalViewControllerAnimated:YES];
}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar

{  
    NSLog(@" searchBarCancelButtonClicked"); …
