UILabel sizeToFit方法无法正常工作 [英] UILabel sizeToFit method not working properly

问题描述

我试图在一行中的UILabel中显示一长段文本. UILabel是UIScrollView的子视图，因此我可以滚动并查看整个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的内容大小足够大，可以显示整个UILable，但是对于像这样的行:

The UIScrollView content size gets big enough to show the entire UILable, but for a line like:

所以我会不时尝试在这里分享其中一些."

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som ...

so i'll try to share som...

我在做什么错了?

推荐答案

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