+### **简介**
+
+> CupertinoTimerPicker 是一个ios风格下的时间选择组件
+
+此选择器显示带有小时、分钟和秒的时间选择器。时间范围为0-23小时, 0-59分钟. 0-59秒.
+
+
+### **基本用法**
+
+
+### **基本实例**
+
+属性说明: 
+
+- initialTimerDuration 初始化时间点
+- minuteInterval 分钟间隔, 我们设置为5, 则分钟选项为0,5,10,15...
+- mode 显示的格式, 我们可以控制该属性, 仅显示小时与分钟, 分钟与秒等, 具体查看 **CupertinoTimerPickerMode**
+- onTimerDurationChanged 时间改变后的回调
+- secondInterval  秒数间隔, 与minuteInterval同
