图片文字的并排布局在项目中非常的常见，iOS系统中没有很好的控件来具体的实现，虽然系统的UIButton的功能可以实现部分此类的功能，但是使用UIButton时自动布局不是太友好，需要固定button 的大小但是实际的开发中button的大小是不固定的，大小是根据图片和文字改变的，而且图片和文字的距离难以设置，通过多个控件(UIImageView ,UILabel)组合也可以实现，如果需要添加点击事件还需要在包装一层view，这种情况会造成代码的冗余，而且相应的文件代码量同样也会增多，基于以上可以封装通用的图片文字混排组件
通过自定义的图文并排，遇到此类的布局不需要过多的控件组合实现，以实现在App的通用，减少代码的量及相应功能的开发时间，使实现的效果更好，提高用户的使用体验。

具体实现
- 自定义View在此View中声明UIImageView，UILabel实现类似于系统按钮的点击方法和图文并排
- 通过枚举实现图文位置，布局的方式，点击的方式
- 声明类似于UIButton的点击方法，给自定义的View添加点击事件
