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

我有一个 UITextView 包含在 UITableViewCell 中.最初显示视图时布局是正确的，但是一旦我单击 UITextView，它会自动向上滚动一点，第一行的上半部分字符变得不可见.

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.

此图像是 UITextView 未激活时的图像:

This image is when the UITextView is not active:

这是当我在 UITextView 中单击以使其处于活动状态时:

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

我根本不使用 UITextView 向上滚动，它应该简单保持固定.我怎样才能做到这一点?我已经在 Interface Builder 中尝试了几种设置，但到目前为止都没有运气.

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.

感谢任何建议.

推荐答案

根据 Apple 的工程师的说法，这是 UITextView 的行为方式，这是预期的，UITextView 适用于高度至少为几行的文本.没有办法解决这个问题，请改用 UITextField 或将 UITextView 的高度增加到至少 3 行.

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.
