})
)(copilot({
tooltipComponent: TooltipComponent,
stepNumberComponent: StepNumberComponent
})(PathexploredTab));
Pathexplorer.js 包含 Pathexplorer 类，其中有一个名为 ToolTipComponent 的组件，我从中调用一个操作，但该操作未反映在 mapStateToProps 中。我被迫这样做的原因是我正在使用一个名为 react-native-copilot 的库，其中我有一个自定义工具提示组件，我想从中访问状态
解决方案
本次活动的问题：
onPress={store.dispatch(action)}
应该：
onPress={()=>store.dispatch(action)}
顺便说一句，您可以连接您的功能组件，如类组件：
export default connect(
mapStateToProps,
mapDispatchToProps
)
)(TooltipComponent)
