最近研究了很久图文混排，本来一开始想研究UILabel的源码，从底层去添加聊天表情。可惜自己刚刚接触Unity 很多东西都不懂，没办法只能另辟蹊径。好在在网上终于找到了解决方案。现在的做法对性能来说肯定不是最好的。不过暂时用用还可以。。等到以后Unity学习得好一点的时候再重新做一个。

下面的代码其实很简单。相信都能看懂。

有些问题希望请教，我QQ139570714,希望能加到您
ChatItem.cs里
NGUIText.size = label.fontSize;
NGUIText.finalSize = label.fontSize;
NGUIText.dynamicFont = label.trueTypeFont;
NGUIText.lineWidth = MaxLineWidth – positionX;
NGUIText.maxLines = 10000;
NGUIText.lineHeight = 10000;
NGUIText.WrapText(value, out sbstr);
UILabel里有Wrap方法的
//修改为固定宽,自适应高度
label.overflowMethod = UILabel.Overflow.ResizeHeight;
label.width = MaxLineWidth – positionX;
label.Wrap(value, out sbstr);
//赋值前修改为全自适应
label.overflowMethod = UILabel.Overflow.ResizeFreely;
label.text = text;
老版本没有NGUIText怎么办，新版的label.wrap也是调用了NGUIText.wrap
最近在做一个网络聊天的UI界面
发送消息这块正常 但接收别人的消息一直都在循环 我是用的UITextList做的 搞了很久也没找到BUG
求帮助 !!!
这个应该是自身逻辑代码，有bug吧。估计不会是NGUI的问题。
[…] 之前发过一个图文混排的文章《[Unity3D学习]NGUI UILabel 图文混排》、一直感觉那样比较消耗。又由于公司项目也需要做图文混排，就想了另一种图文混排思路，从性能来说比之前的思路要好很多，不过也有弊端，现在这种解决方案，做动态表情不太适应。不过我想的是，手机游戏对聊天功能其实已经比较弱化了，所以个人认为聊天不需要做得太复杂，一切从简就好。 […]
