如何在输入时阻止UITextView向上滚动 [英] How to stop UITextView from scrolling up when entering it

问题描述

我在 UITableViewCell 中包含 UITextView 。最初显示视图时布局是正确的，但是一旦我点击 UITextView ，它会自动向上滚动一下，第一行上的字符的上半部分变为不可见。

I have a UITextView included in a UITableViewCell. The layout is correct when the views are initially displayed, but once I click in the UITextView it automatically scrolls up a bit and the top half of the characters on the first line becomes invisible.

此图片是 UITextView 未激活的时间：

This image is when the UITextView is not active:

这是当我点击 UITextView 使其激活时：

And this one is when I clicked in the UITextView to make it active:
UITextView active http://gerodt.homeip.net/uitextview-active.png

I不要UITextView向上滚动，它应该简单地保持固定。我怎样才能做到这一点？我已经在 Interface Builder 中尝试了几个设置，但到目前为止还没有运气。

I do not the UITextView to scroll up at all, it should simple stay fixed. How can I achieve this? I already tried several settings in Interface Builder, but no luck so far.

任何建议都表示赞赏。

推荐答案

根据Apple工程师的说法，这是UITextView的行为方式intent和UITextView适用于高度至少为几行的文本。没有解决方法，使用UITextField代替或将UITextView增加到至少3行高。

This is how UITextView behaves according to Apple's engineer this is intended and UITextView is meant for text that are at least a few lines in height. There is no work around to this, use a UITextField instead or increase your UITextView to at least 3 lines in height.
