从v3.9.x升级到MUI v4.0.2后,出现以下错误:
您必须将组件传递给connect返回的函数。而是收到{“ propTypes”:{},“ displayName”:“ WithStyles(MyComponent)”,“ options”:{“ defaultTheme”:{“ breakpoints”:{“ keys”:[“ xs”,“ sm”,“ md“,” lg“,” xl“],”值“: ...
MyComponent:
import { connect } from 'react-redux'
import MyComponent from './MyComponent'
...
export default connect(mapStateToProps, mapDispatchToProps)(MyComponent)
MyContainer:
withStyles
如何迁移 func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
/*
for facebook login
*/
if #available(iOS 9.0 , *){
return ApplicationDelegate.shared.application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplication.OpenURLOptionsKey.annotation])
}
/*
for google signin
*/
return GIDSignIn.sharedInstance().handle(url as URL?,
sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplication.OpenURLOptionsKey.annotation])
}
?

react-redux的版本5.0.7和更早版本对传递给connect
的组件执行了以下验证:
https://github.com/reduxjs/react-redux/blob/v5.0.7/src/components/connectAdvanced.js#L91
invariant(
typeof WrappedComponent == 'function',
`You must pass a component to the function returned by ` +
`${methodName}. Instead received ${JSON.stringify(WrappedComponent)}`
)
通过引入React.forwardRef
(在Material-UI v4中大量使用)和React 16.8中引入的其他功能(挂钩),可以使用不是的组件类型。 strong>一个功能。
React-redux的最新版本改用react-is
包中的isValidElementType。这样可以正确识别forwardRef
和其他方法返回的组件类型。
我相信react-redux的5.1版和更高版本应该都能正常工作,而不会错误地引起问题中提到的错误。

这是我的方法:
import { withStyles } from '@material-ui/core/styles';
定义样式对象:查看material-ui示例以获取指导
const styles => ({
root: {
display: 'flex',
}
});
然后使用您的样式导出组件:
export default withStyles(styles)(YourComponent);
