最近准备做一个聊天系统,开始准备使用cocos2dx的UIRichText控件来显示聊天内容,结果在使用的时候才发现,cocos2dx的RichText功能非常有限,完全不具备实现聊天的功能,只实现了加入文本、图像和自定义控件的功能,支持不同字体、颜色、字号。

      我个人认为,一个RichText控件应该具备以下基本功能:

      1、多样化的文本显示功能,包括字体、颜色、字号的设置。

      2、能显示图片以及一些特殊元素。

      3、应该支持图片文字的超链接功能。

      4、能够支持滚动的效果。

      5、能够有很方便的换行功能,最好能设置行间距。

      如果能够更好的实现聊天的功能,我觉得还需要加入以下功能:

      1、文本特效:描边,下划线,阴影,发光等功能。

      2、支持设置控件最大显示行数。

      3、支持数据的分类显示,用于分频道显示聊天内容。

      cocos2dx只实现了基础的1和2功能,所以考虑之后还是决定自己写一个RichText控件。UIRichText的框架还是不错的,实现了文本分行显示的技术。在他的基础上很容易扩展。 

      首先,扩展RichItem,用来支持多样化的文本需求。

      其次,扩展Label控件,用于支持特殊的文字效果。

      再次,需要实现滚动功能,控件继承UIScrollView。

      最后,还需要对lua进行支持,包括使用功能以及超链接点击事件的注册。

      以上是我实现控件的思路,这里就不贴代码了,很多,我会把我的控件代码共享给大家,大家在使用中有什么问题也可以向我咨询。

      最后贴一下使用的代码和效果图吧!

      使用代码如下,我是在lua里面使用的,大家可以参考一下:
