如何在UIPickerView顶部添加UIToolbar? (iPhone/iPad) [英] How to add a UIToolbar on top of UIPickerView? (iPhone/iPad)

问题描述

在我的应用程序中，我有一个按钮，当按下该按钮时，应在其顶部显示一个UIPickerView和一个UIToolbar.当用户在UIPickerView中选择了值后，他们将按UIToolbar中的按钮，同时取消UIPickerView和UIToolbar.

In my app I have a button that when pressed should present a UIPickerView with a UIToolbar on top of it. When the user has selected the value in the UIPickerView they then press a button in the UIToolbar which dismisses both the UIPickerView and UIToolbar.

我遇到的问题是我不知道将UIToolbar添加到UIPickerView的方法.通常我会进行UITextField中的值受UIPickerView中的选择影响的设置.这样，我可以简单地将UIToolbar设置为inputAccessoryView，但是，这次我没有UITextField.

The problem I'm having is that I can't figure out a way to add the UIToolbar to the UIPickerView. Normally I would have a setup where a value in a UITextField is impacted by the selection in the UIPickerView. This way I can simply set the UIToolbar as the inputAccessoryView, however, this time round I don't have a UITextField.

请问有人可以建议如何在UIPickerView顶部添加UIToolbar吗?

Please can someone advise on how to add the UIToolbar on top of the UIPickerView?

推荐答案

为此的最佳解决方案是使用UIActionSheet.

Best Solution for this is make use of UIActionSheet.

只需创建UIActionSheet的全局对象，然后将UIToolbar和UIPickerview添加到UIActionSheet作为子视图.

Just Create Global of UIActionSheet,add Your UIToolbar and UIPickerview to UIActionSheet as subview.

最后在主视图的子视图中添加UIActionSheet.

At last add UIActionSheet in subview of your main View.
