问题描述
我正在使用本机反应式0.62.2版本和datetimepicker版本3.0.1。当我尝试使用xcode构建项目时，显示以下错误：
- 使用未声明的标识符'UIDatePickerStyleCompact'
- 使用未声明的标识符'UIDatePickerStyleWheels'
- 在类型的对象上找不到属性'preferredDatePickerStyle' “ RNDateTimePicker *”
- 在类型的对象上找不到属性'preferredDatePickerStyle' 'UIDatePicker *'
- “ NSInteger”（又名“ long”）到“ id”的隐式转换是 不允许使用ARC
- 声明需要整数类型（'__strong id' 无效）
- “ UIDatePickerMode”（又名“枚举”）的隐式转换 ARC不允许将UIDatePickerMode'）更改为'id'
- 使用未声明的标识符'UIDatePickerStyleWheels'
以下是 RNDateTimePickerManager.h

react-native datetimepicker中是否存在任何错误？
