UIFont fontWithName返回nil [英] UIFont fontWithName returns nil

问题描述

在我的info.plist中，我添加了一个键应用程序提供的字体，并添加了 EdwardianScriptITCStd.otf

  NSLog（@％@，[UIFont fontWithName：@EdwardianScriptITCStd

解决方案

我的意见开始变长，所以我决定提交一个答案： ）

1. 自定义字体仅在iOS 3.2及更高版本中受支持，因此请确保您的部署目标构建设置不会返回

验证字体是否包含在构建目标中（在复制捆绑资源构建阶段）
/ li>


2. 检查应用程序提供的字体键的原始值，以确保它是正确的。在Xcode中查看* .plist时，右键单击并选择显示原始键/值，然后验证键是 UIAppFonts 。




3. 我相信当使用 fontWithName：size：时，iOS需要一个字体的PostScript名称，您可以通过打开字体在Apple's Font Book中输入命令+ I 。




4. 使用自定义字体和 UILabel 。我不知道这个问题是否仍然存在。

编辑

不能保证我有与您相同的字体文件，但在我的机器上PostScript名称是EdwardianScriptITC

In my info.plist, I added a key "Fonts provided by application" and added EdwardianScriptITCStd.otf

But, when I try to get that font, it returns nil:

NSLog(@"%@", [UIFont fontWithName:@"EdwardianScriptITCStd" 
                                size:16.0f]);

I printed the font families using [UIFont familyNames] and it's not there either:

What am I missing? Thanks!

解决方案

My comments were starting to get lengthy, so I've decided to submit an answer instead :)

1. Custom fonts are only supported in iOS 3.2 and above, so make sure your Deployment Target build setting doesn't go back any farther than version 3.2.

2. Verify that the font is included in your build target (in the "Copy Bundle Resources" build phase)

3. Check the raw value of the key for "Fonts provided by application" to make sure it's correct. When viewing the *.plist in Xcode, right-click and choose "Show Raw Keys/Values", then verify the key is UIAppFonts.

4. I believe iOS requires the PostScript name for a font when using fontWithName: size:, which you can find/verify by opening the font in Apple's Font Book and typing command+I.

5. At one point, there was an issue with using custom fonts and UILabel. I am not sure if this problem still exists. The solution was to subclass UILabel and set the font therein.

If it still doesn't work, this Stack Overflow thread on custom fonts has quite a bit of info, you may have some luck there.

EDIT
There's no guarantee that I have the same font file as you, but on my machine the PostScript name is "EdwardianScriptITC"
