UILabel sizeToFit 方法无法正常工作

问题描述

我试图在一行中的 UILabel 中显示一大段文本.UILabel 是 UIScrollView 的子视图，因此我可以滚动查看整个 UILabel.

I'm trying to show a long chunk of text inside a UILabel in one line. The UILabel is a subview of UIScrollView so I can scroll and see the entire UILabel.

我的问题是 sizeToFit 方法仅部分有效.

My problem is that the sizeToFit method only partialy works.

textLabel.attributedText = attributedString;
textLabel.numberOfLines = 1;
[textLabel sizeToFit];
textScrollView.contentSize = CGSizeMake(textLabel.frame.size.width, textLabel.frame.size.height);

UIScrollView 内容大小变得足够大，可以显示整个 UILable，但是对于这样的一行:

所以我会尝试每隔一段时间在这里分享一些."

so i'll try to share some of them here every once in a while."

UILabel 显示:

The UILabel shows:

所以我会尝试分享一些...

so i'll try to share som...

我做错了什么?

推荐答案

Turns out the code is just fine - but the Use Autolayout was checked. Unchecked it - everything works just great...
