在iOS中 - 如何在不改变其位置的情况下将UILabel放入其文本中？ [英] In iOS - How do I fit a UILabel to its text, without changing its position?

问题描述

我在 UILabel 上调用 sizeToFit ，其中包含右对齐文本。它缩小了 UILabel 的高度和宽度，并使文本适合 UILabel 的左上角。

I'm calling sizeToFit on a UILabel which has right aligned text in it. It shrinks the height and width of the UILabeland fits the text to the top left of the UILabel.

现在...... UILabel 的位置不正确。如何让 UILabel 保持原始位置（右对齐）或移动它以使其显示在原始位置？

Now...the position of the UILabel is incorrect. How can I make the UILabel stay in its original position (right aligned) or move it so it'll appear at its original position?

再一次 - 问题是 sizeToFit 方法正在缩小 UILabel 。它将 UILabel 文本视为左对齐。但我的文字是正确对齐的。因此， UILabel 的右侧边框是我的文字开头的地方。

Once again - the problem is that the sizeToFit method is shrinking the width from the right side of the UILabel. It is treating the UILabel text as left aligned. But my text is right aligned. So, the right side border of the UILabel is where my text begins.

推荐答案

你检查之前和之前的宽度之后，然后将视图的中心向右移动差值/ 2.

You check the widths before & after, then move the center of the view right by the difference / 2.

顺便说一下，我认为盒子（框架）在两个方向都缩小了，保持中心完整。

By the way, I think the "box" (frame) is shrunk in both directions, keeping the center intact.
