The Pis the props type and the Sis the state type. You'll want to change:
该P是道具类型和S是状态型。你会想要改变：
class MyComponent extends React.Component { ...
class MyComponent extends React.Component { ...
to:
到：
interface MyProps {}
interface MyState {}
class MyComponent extends React.Component<MyProps, MyState> { ...
Then expand the MyPropsand MyStateinterfaces to include typing for all the props and state that the component needs.
然后扩展MyProps和MyState接口以包括输入组件所需的所有道具和状态。
