ios开发之--仿（微信）自定义表情键盘

先附上demo：https://github.com/hgl753951/CusEmoji.git

效果图如下：

先说下具体的实现功能：

1，本地加载了一些H5的代码，直接使用webview的load方法加载出来的

2，获取web的动态高度，然后创建tableview，把webview加到一个tableview的headerview上，

3，实现cell的自定义高度，是用xib实现的

4，评论功能的实现，自定表情键盘，可以发送表情，文字等相关信息

这个demo里面有2个效果，第一个是我自己写的很粗糙，没有加表情键盘，第二个是加了表情键盘的。

话不多了，代码如下：

逻辑很简单也很清晰，先[self initInputView]-->[self createView];&& [self creatWebView];-->在webViewDidFinishLoad里面走[self creatTableView];方法，动态高度是用Masonry实现的！希望能帮到大家，代码是完整的，可以直接复制粘贴使用！demo和代码没有详细整理，注释也不多，后期我会完善的，加上回复等相关功能！
