我正在使用redux处理react-native app . 我无法从数组中删除特定项目 . state.tournaments是数组，我要删除的项必须包含我从动作发送到redux的ID .
这是我的减速机：
import {
TOURNAMENT_NAME_CHANGED,
TOURNAMENT_CREATE,
SAVE_TOURNAMENT,
DELETE_TOURNAMENT
} from '../actions/types';
const INITIAL_STATE = {
name: null,
admin_token: null,
tournaments: []
};
export default (state = INITIAL_STATE, action) => {
switch (action.type) {
case TOURNAMENT_NAME_CHANGED:
return { ...state, name: action.payload };
case TOURNAMENT_CREATE:
return { ...state, admin_token: action.payload.data.admin_token };
case SAVE_TOURNAMENT:
return { ...state, tournaments: [...state.tournaments, action.payload] };
case DELETE_TOURNAMENT:
return { ...state, tournaments: state.tournaments.filter((name, id) => id !== action.payload.id) };
default:
return state;
}
};

你没有正确使用过滤器，试试这个：
