Reset text in textfield of UISearchBar when X button is clicked, but not resign firstresponder
提问by Magnus
I have a view with a UISearchBar in it. However, when the "X" button in the searchbar is clicked, it removes the keyboard but doesn't remove the text in the textfield of the searchbar. What I want is this: When the user clicks the x button, the text in the textfield is reset but the keyboard stays up.
我有一个带有 UISearchBar 的视图。但是，当单击搜索栏中的“X”按钮时，它会删除键盘，但不会删除搜索栏文本字段中的文本。我想要的是：当用户单击 x 按钮时，文本字段中的文本被重置但键盘保持不动。
How can I do this?

This seems to do the trick for me. Make sure your View Controller is a UISearchBarDelegate
这似乎对我有用。确保您的视图控制器是 UISearchBarDelegate
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
searchBar.text = @"";
}

try implementing UISearchBarDelegate's method -(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBarand return NOas the result.
尝试实现UISearchBarDelegate的方法-(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar并NO作为结果返回。
E.g.:
例如：
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{
return NO;
}
