NSAttributedString - 获取字体属性 [英] NSAttributedString - get font attributes

问题描述

我需要获取有关我的属性字符串的信息，但无法弄清楚如何。我收到这本词典：

I need to get info about my attributed string but can't figure out how. I'm getting this dictionary:

2013-11-04 18:06:10.628 App[1895:60b] {
    NSColor = "UIDeviceWhiteColorSpace 0.3 1";
    NSFont = "<UICTFont: 0x17d8d4c0> font-family: \".HelveticaNeueInterface-MediumP4\"; font-weight: bold; font-style: normal; font-size: 17.00pt";
    NSUnderline = 0;
}

很容易检查下划线：

[attrs objectForKey:@"NSUnderline"]

但如何获取字体信息，如字体样式，字体重量等。

But how to get info about font like the font-style, font-weight etc.

感谢您的帮助

推荐答案

您可以从以下字体获取字体：

You get the font from:

UIFont *font = attrs[NSFontAttributeName];

问题在于确定它是否为粗体。没有财产。唯一的选择是查看字体的 fontName ，看看是否包含Bold或其他类似术语。并非所有粗体字体在名称中都有粗体。

The issue is determining whether it is bold or not. There is no property for that. The only option is to look at the fontName of the font and see if contains "Bold" or some other similar term. Not all bold fonts have "Bold" in the name.

同样的问题适用于确定字体是斜体还是注释。您必须查看 fontName 并查找Italic或Oblique等内容。

The same issue applies for determining of the font is italic or note. You have to look at the fontName and look for things like "Italic" or "Oblique".
