iphone - 如何删除 UISearchBar 中的工具提示

Question

我仍在开发我的应用程序，并且对 UISearchBar 有疑问。 这是我的问题:如何摆脱 UISearchBar 中出现的“选择|全选|粘贴”工具提示？ 谁能帮我这个？预先感谢您。

如果您只想为 UISeacrhBar 隐藏它，则:

-(void)setGestures
{
    for (id obj in searchBar.subviews)
    {
        if ([obj isKindOfClass:[UITextField class]])
        {
            UITextField *textF = (UITextField *)obj;
            textF.gestureRecognizers = nil;
            UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(makeSearchBarFirstResponder:)];
            textF.gestureRecognizers = @[tapGesture];
        }
    }
}

-(void)makeSearchBarFirstResponder:(UIGestureRecognizer *)sender
{
    [sender.view becomeFirstResponder];
}

并在

中调用[self setGestures]方法

-(void)viewDidLoad
{
   [self setGestures];
}
-(BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
   [self setGestures];
   return YES;
}
