ios - 为什么按下 UISearchbar 上的取消按钮时会出现 UIKeyboard？

Question

我正在使用以下代码在 iOS7 中添加 UISearchBar 并且 UISearchBar 外观很好。但是问题是当按下 UISearchBar 上的取消按钮时UIKeyboard 出现了。为什么会这样？请帮助我。

CGRect searchFrame = CGRectMake(self.view.bounds.origin.x, 64, self.view.bounds.size.width, 44.0f);
self.mySearchBar = [[UISearchBar alloc]initWithFrame:searchFrame];
self.mySearchBar.delegate = self;
self.mySearchBar.searchBarStyle = UISearchBarStyleDefault;
self.mySearchBar.placeholder = @"search items;
self.mySearchBar.showsCancelButton = YES;
[self.view addSubview:self.mySearchBar];

Answer 1

实现 searchBarCancelButtonClicked: UISearchBarDelegate 方法。如果您希望键盘消失，您可以执行以下操作:

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