警告:可能会出现未处理的承诺拒绝(id:0)
TypeError:对象不是函数(正在评估'concreteComponentProvider()')
这是在我的应用程序中添加React Redux后收到的警告。关于React Redux和React Native Navigation(最新版本)或React Native Vector图标可能会有些冲突。
我认为导致错误的原因是这段代码startMainTabs.js
。这是我编写所有React Native Navigation的地方。
随时询问我的更多代码或任何问题。谢谢!
这些是我的代码: App.js
import {Provider} from 'react-redux';
import configureStore from './src/store/configureStore';
const store = configureStore();
//Register Screens
Navigation.registerComponent("Event.AuthScreen", () => AuthScreen);
Navigation.registerComponent("Event.Map", () => EventMap);
Navigation.registerComponent("EventCreator", () => EventCreator, store, Provider);
Navigation.registerComponent("EventHome", () => EventHome, store, Provider);
Navigation.setRoot({
root: {
stack: {
children: [{
component: {
name: "Event.AuthScreen",
}
}],
options: {
topBar: {
title: {
text: 'Welcome'
}
}
}
}
}
});
startMainTabs.js
const startTabs = () => {
Promise.all([
Icon.getImageSource("ios-home", 30),
Icon.getImageSource("ios-map", 30),
Icon.getImageSource("ios-share-alt", 30)
]).then(sources => {
Navigation.setRoot({
root: {
bottomTabs: {
children: [{
stack: {
children: [{
component: {
name: "Event.Map",
}
}],
options: {
bottomTab: {
icon: sources[1],
testID: 'FIRST_TAB_BAR_BUTTON'
}
}
}
},
{
stack: {
children: [{
component: {
name: "EventHome"
}
}],
options: {
bottomTab: {
icon: sources[0],
testID: 'SECOND_TAB_BAR_BUTTON'
}
}
}
},
{
component: {
name: "EventCreator",
options: {
bottomTab: {
icon: sources[2],
testID: 'THIRD_TAB_BAR_BUTTON'
}
}
}
}
]
}
}
});
})
}

您应该使用来自wix的最新版本的react native导航
registerComponentWithRedux
而非registerComponent
,
并在存储前设置提供者
答案 1 :(得分:0)
registerComponent
在最新版本的RNN中,您应该使用Provider
而不是store
,并且grep -A 5 -B 5 somestring file.txt
首先出现,然后是$ grep -A 2 -B 1 four tmp.text
three
four
five
six
$ cat tmp.text
one
two
three
four
five
six
seven
,就像上面的代码示例一样
