如何在点击键盘上有关 UISearchBar 的搜索按钮时关闭键盘？

发布于 2024-12-22 00:01:58 字数 191 浏览 0 评论 0原文

我正在开发一个应用程序，其中添加一个控件 UISearchBar。当我开始在 UIsearchBar 中编辑文本时，键盘会在屏幕上显示动画。当我完成完整的编辑或取消所有文本后，我将停留在关闭键盘的位置。如何在点击 UIKeypad 中的搜索键时关闭键盘？

UITextField 和 UITextView 也有同样的问题吗？

谢谢

确保具有 SearchBar 的视图控制器实现了 SearchBarDelegate 并将 searchBar.delegate 设置为 self:

@interface AddressSearchViewController : UIViewController <UISearchBarDelegate>

然后实现以下方法：

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

这将使当您点击键盘或搜索栏上的搜索按钮时键盘消失

Make sure the view controller which has the SearchBar implements the SearchBarDelegate and you set the searchBar.delegate to self:

@interface AddressSearchViewController : UIViewController <UISearchBarDelegate>

then implement the following method:

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

This will make the keyboard disappear when you tap the search button on the keyboard or the search bar

对于搜索栏：

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

对于文本字段也是如此：

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
}

For the search bar:

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

And same thing for the text field:

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
}

在 ViewDidLoad 中使用此代码

-(void) ViewDidLoad
 {
    [super ........];
    UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
    [self.view addGestureRecognizer:gestureRecognizer];
    gestureRecognizer.cancelsTouchesInView = NO;    
 }

 - (void) hideKeyboard 
 {
    [texfieldname1 resignFirstResponder];
    [texfieldname2 resignFirstResponder];
 }

Use this code in ViewDidLoad

-(void) ViewDidLoad
 {
    [super ........];
    UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
    [self.view addGestureRecognizer:gestureRecognizer];
    gestureRecognizer.cancelsTouchesInView = NO;    
 }

 - (void) hideKeyboard 
 {
    [texfieldname1 resignFirstResponder];
    [texfieldname2 resignFirstResponder];
 }
