有没有办法将UITextView的滚动指示器放到UITextView外面？ [英] Is there a way to put UITextView's scroll indicator to outside UITextView?

问题描述

这可能是一个愚蠢的问题。
我正试图设置左/右边距，如附图。我通过将UITextView添加到UIScrollView来成功实现它。
然而，我可以单独使用UITextView实现我想要的几乎所有东西。例如，使用UIScrollView，当我手动更改UITextView的文本时，无论将.scrollEnabled设置为否，它都会自动滚动到底部。

It might be a silly question. I'm trying to set left/right margins like the attached picture. I succeeded to implement it by adding UITextView to UIScrollView. However, I could achieve almost everything I want with UITextView alone. For example, with UIScrollView, when I manually change the text of UITextView, it automatically scrolls to bottom regardless of setting its .scrollEnabled to No.

如果是UITextView的滚动指示符出现在UITextView外部。
在附图中，假设红色框代表整个UITextView。我试图更改UITextView的scrollIndicatorInsets属性，但滚动指示器只能向内移动才能看到。

It would be perfect if a scroll indicator of UITextView appears outside UITextView. In the attached picture, let's say the red box represents the entire UITextView. I tried to change UITextView's scrollIndicatorInsets property, but a scroll indicator can be moved only inward to be visible.

诸如Pages，aWriter，Plaintext等几个应用程序实现了这一功能。
您能给出任何建议吗？

Several apps such as Pages, aWriter, Plaintext achieve this feature. Could you give any suggestion?

谢谢！

推荐答案

您可以设置滚动条右侧插入UITextView的值为负值，并禁用剪辑子视图选项以达到您的要求。不需要其他滚动视图。

You can set the scroller right inset value of the UITextView to negative value and disable the clip subview option to achieve your require. No other scrollview is needed.
