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！

iOS开发项目篇—28自定义UITextView 一.简单说明 1.要实现的效果 2.分析 (1)UITextField 1.最多只能输入一行文字 2.能设置提醒文字(placehoder) 3.不具备滚动功能 (2)UITextView 1.能输入N行文字(N>0) 2.不能设置提醒文字(没有placehoder属性) 3.具备滚动功能 需求:技能输入多行文字,又具备文字提醒功能. 这里选择自定义一个类,让其继承自UITextView类,为其添加一个设置文字提醒的功能. 二.实现 自定义UI控

iOS开发项目篇—27自定义UITabBar

iOS开发项目篇—27自定义UITabBar 一.自定义 思路: (1)新建一个继承自UITabBar的类,自定义一个UITabBar (2)用自定义的UITabBar换掉系统的UItabBar(使用了KVC) (3)监听控制器的切换,只要控制器一切换,就调用代理方法强制重新布局子控件(内部会调用layoutSubviews). YYTabBar.m文件代码: 1 // 2 // YYTabBar.m 3 // 4 5 #import "YYTabBar.h" 6 7 @interfa
