我设置了我的xcode项目,以便我成功地使用facebook库。我在index.ios.js文件中有以下代码:
/**
* Sample React Native App
* https://github.com/facebook/react-native
* @flow
*/
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
const FBSDK = require('react-native-fbsdk');
const {
LoginButton,
AccessToken
} = FBSDK;
var Login = React.createClass({
render: function() {
return (
<View>
<LoginButton
publishPermissions={["publish_actions"]}
onLoginFinished={
(error, result) => {
if (error) {
alert("login has error: " + result.error);
} else if (result.isCancelled) {
alert("login is cancelled.");
} else {
AccessToken.getCurrentAccessToken().then(
(data) => {
alert(data.accessToken.toString())
}
)
}
}
}
onLogoutFinished={() => alert("logout.")}/>
</View>
);
}
});
export default class FacebookReactNativeTest extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.ios.js
</Text>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
AppRegistry.registerComponent('FacebookReactNativeTest', () => FacebookReactNativeTest);
可悲的是,Facebook登录的东西并没有出现在这里的视图中,但FacebookReactNativeTest中的东西是。我似乎没有添加为视图创建的Login var,因为我是React Native的新手,我不知道如何手动添加它。我怎样才能做到这一点?
答案 0 :(得分:0)
弄清楚这是应该怎么做的:
/**
* Sample React Native App
* https://github.com/facebook/react-native
* @flow
*/
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
const FBSDK = require('react-native-fbsdk');
const {
LoginButton,
AccessToken
} = FBSDK;
var Login = React.createClass({
render: function() {
return (
<View>
<LoginButton
publishPermissions={["publish_actions"]}
onLoginFinished={
(error, result) => {
if (error) {
alert("login has error: " + result.error);
} else if (result.isCancelled) {
alert("login is cancelled.");
} else {
AccessToken.getCurrentAccessToken().then(
(data) => {
alert(data.accessToken.toString())
}
)
}
}
}
onLogoutFinished={() => alert("logout.")}/>
</View>
);
}
});
export default class FacebookReactNativeTest extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>

</Text>
<Text style={styles.instructions}>

<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>

<Login />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',

AppRegistry.registerComponent('FacebookReactNativeTest', () => FacebookReactNativeTest);
