在UIView中将字符串的部分设置为粗体 [英] Setting parts of a String to Bold in UIView

问题描述

我解析一个XML文件，得到一个字符串 NSMutableString 。
现在我想在 UIView 中将此字符串显示为文本。
所以，我创建了一个 TextView 并将其值设置为我的字符串。结果是我有Text标签中显示的HTML标签的文本。

从字符串中删除标签没有问题，但有些文本需要

是否有任何方法可以以编程方式显示字符串的某些部分？

< br> 元素与 \\\
，它适用于换行符。

但是我仍然不知道我可以做什么，在 UIView 中的粗标签之间显示字词。

解决方案

有两种方法。第一种是通过在UIWebViews中显示它们;在iOS 4.1之前这是有效的唯一方法。

如果您确定您的应用程式只能在iOS 4.1以上运行，您可以使用Core

I'm parsing an XML file an get a string as NSMutableString. Now I want to show this string as text in my UIView. So, I created a TextView and set its value to my string. The result was that I have the text with HTML Tags shown up in the TextView.

There is no problem removing the tags from the string, but some of the text needs to appear as bold.

Is there any way to display parts of a string as bold programmatically?

I replaced <br> Elements with \n and it works fine for line-break.

But I still don't know what I can do to display words between strong tags as bold in the UIView.

解决方案

There are two ways. The first is by displaying them in UIWebViews; prior to iOS 4.1 this was effectively the only way. Because you already have HTML codes in the text, it would certainly be easy.

If you're ok with your app running only on iOS 4.1 and up you can use Core Text, which provides very rich formatting.
