自定义键盘的核心思想
- 设置UITextFiled 的InputView
- 切换键盘的思路为重新设置UITextFiled 的InputView然后再调用textFiled?.reloadInputViews()
*剩下的就是按键的布局与代理设置了
swift版本采用策略模式实现，Objc版本使用常规模式实现
- 策略模式请参看另一编文章https://blog.csdn.net/d06110902002/article/details/75642548
swift版本的策略模式实现的角色划分如下：
- 策略管理类–键盘管理类KeyboardMgr
- 通用策略类–键盘基类KeyboardBaseView
- 具体的策略类–数字键盘、随机数字键盘、英文键盘
##具体的源码如下：
