objective-c - 在 uikeyboard 顶部添加工具栏

Question

我有一个工具栏，我想将它放在键盘的顶部。

在 keyboardwillshow 通知中，我尝试将工具栏添加到键盘，但没有成功，我无法添加

请告诉我

UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
    UIView* keyboard;
    for(int i = 0; i < [tempWindow.subviews count]; i++)
    {
        //Get a reference of the current view 
        keyboard = [tempWindow.subviews objectAtIndex:i];

        //Check to see if the description of the view we have referenced is "UIKeyboard" if so then we found
        //the keyboard view that we were looking for
        if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
        {
            [keyboard addSubview:myToolbar];
        }
    }

我想，你想要一个 inputAccessoryView .

基本上，您创建一个 View 并将其设置为文本字段或 TextView 的输入辅助 View 。

[textField setInputAccessoryView:inputAccessoryView];
