如何使用Unity UI滚动到ScrollRect中的特定元素? [英] How to scroll to a specific element in ScrollRect with Unity UI?

问题描述

我使用Unity 5.1为手机游戏建立了注册表. 为此，我使用 Unity UI 组件:ScrollRect +自动布局(垂直布局)+文本(标签)+输入字段. 这部分工作正常.

I built a registration form for a mobile game using Unity 5.1. To do that, I use Unity UI components: ScrollRect + Autolayout (Vertical layout) + Text (labels) + Input Field. This part works fine.

但是，当打开键盘时，所选字段位于键盘下方.是否可以通过编程方式滚动表单以使选定字段显示在视图中?

But, when keyboard is opened, the selected field is under keyboard. Is there a way to programmatically scroll the form to bring the selected field into view?

我尝试使用ScrollRect.verticalNormalizedPosition，滚动一些内容效果很好，但是我无法使所选字段出现在我想要的位置.

I have tried using ScrollRect.verticalNormalizedPosition and it works fine to scroll some, however I am not able to make selected field appear where I want.
