问题 I am using the tabnavigator (createbottomBottomTabNavigator) and need help with the bage count using redux. 回答1: There is custom way to do this using redux, you can make your custom component using the same :- screen: NotificationScreen, navigationOptions: { tabBar: (state, acc) => ({ icon: ({ tintColor, focused }) => ( <BadgeTabIcon iconName="notification" size={26} selected={focused} /> ), visible: (acc && acc.visible !== 'undefined') ? acc.visible : true, }), }, }, where, export default

问题 In redux saga if we want to handle multiple promises, we can use all (which is equivalent of Promise.all ): yield all( users.map((user) => call(signUser, user)), ); function* signUser() { yield call(someApi); yield put(someSuccessAction); } The problem is , even if one of the promises (calls) fail, the whole task is cancelled. My goal is to keep the task alive , even if one of the promises failed. In pure JS I could handle it with Promise.allSettled , but whats the proper way to do it in

问题 For example I want to remove the dispatch: any here: export const fetchAllAssets = () => (dispatch: any) => { dispatch(actionGetAllAssets); return fetchAll([getPrices(), getAvailableSupply()]).then((responses) => dispatch(actionSetAllAssets(formatAssets(responses)))); } There are 2 actions I dispatch above, actionsGetAllAssets and actionsSetAllassets . Here are the interfaces and actionCreators for both: // Interfaces interface IActions { GET_ALL_ASSETS: string; SET_ALL_ASSETS: string; GET
