篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Unity编辑器下，界面替换NGUI字体以及字号相关的知识，希望对你有一定的参考价值。
项目中有需要批量替换字体以及字号的需求，一般也就是多语言处理吧。
提供界面如下：
手机拍图，就这样凑合看吧。但是代码不打折。
紧急避让，我只提供修改UILabel以及UIPopupList 下的字体，字号。其他需求的，可以绕远了。还有哈，代码写的很渣渣，因为自己用嘛。还有所有权归我本人所有，一切用于商业用途的，请自己联系博主，上缴费用，谢谢~~~~（赚钱好方法）

谁能帮我用NGUI做个简单的UNITY3D的界面，就是最普通的那种有登陆界面，确认返回，以及切换的3个界面。
