在iPad应用程序中嵌入字体的方法
摘自:韩磊的博客 http://blog.csdn.net/grhunter/archive/2010/11/03/5985491.aspx
今天为21世纪报系一个iPad应用做技术验证,尝试在应用中加入iPad没有的字体。先Google了一下,解决方案很简单,iOS 3.2以上都支持内嵌用户字体。介绍这个技术的blog文章或论坛帖子很多,也有中文写的,但中文的文章或帖子,几乎全是人云亦云。我猜这些可敬的作者们,多半没有自己去验证过,或者验证之后不愿把遇到的问题和解决方案分享出来。
进入正题。在iOS 3.2以上支持内嵌字体的方法,可以分为三个步骤:
1、把字体文件添加到项目的Resources文件组(千万别说你不会哦);
2、在项目的Info.plist文件中添加UIAppFonts项(类型为Array),并把字体文件名作为元素写进去;
3、在项目代码中引用字体:如 label.font = [UIFont fontWithName:@”字体名” size: 14.0f]。
简单吗?很简单。可是,如果你尝试内嵌中文字体(如Mac里面的“华文仿宋”),也许就会遇到问题。你已正确地将字体放到Resources文件组,正确地填写了Info.plist文件,而且,label.font = [UIFont fontWithName:@”华文仿宋” size:14.0f]也没有报错。好,Build and Go!怎么回事?标签文字并非如你所愿的仿宋,还是默认的Georgia字体。
这就是我说大多数中文作者都没有亲自验证的原因——或者他们都只开发英文软件?若你对字体的相关概念不熟悉,遇到这个问题太正常了。说穿了很简单,上述第三步中,必须使用字体的真实名称(family name),而不是字体文件名!
那么,“华文仿宋”的真实名称是什么?不必依赖搜索引擎,三行代码就可以找到:
在Debugger Console窗口,你将看到一大堆iPad系统支持的字体名称:

你内嵌的“华文仿宋”也在其中,但它改头换面,成了“STFangsong”。没错,这就是华文仿宋的Family Name,也是代码中应该使用的字体名称。把代码改为:
labelChinese.font = [UIFont fontWithName:@”STFangsong” size:43.0f];
labelChinese.text = @”测试”;
运行效果如下(我还添加了英文字体Comic Sans MS):
