无法在react native中获取iOS推送通知设备令牌

react-native-ios react-native

我提到 this question 获取设备令牌以向我的应用发送推送通知。我使用创建了我的应用程序 create-react-native-app 。代码如下:

import React, { Component } from 'react';
import {
  Platform,
  StyleSheet,
  AppRegistry,
  Text,
  View,
  PushNotificationIOS
} from 'react-native';

type Props = {};

export default class Apptitude extends Component<Props> {
  constructor() {
    console.log('registering evt listerner in launchpad')
    PushNotificationIOS.addEventLister('register', (token) => {
      this.setState({
        deviceToken: token
      })
    });
  }

  render() {
    return (
      <View>
      </View>
    );
  }
}

PushNotificationIOS.addEventListener('registrationError', (registrationError) => {
  console.lo('was error')
  console.log(reason.message)
  console.log(reason.code)
  console.log(reason.details)
})
// yes I'm aware I've added an event listener in the constructor also. Neither of these callbacks fire
PushNotificationIOS.addEventListener('register', (token) => {
  console.log('this is the token', token);
});
console.log('requesting permissions')
PushNotificationIOS.requestPermissions();

问题是 register 以及 registrationError 事件永远不会发生。系统会提示我批准权限,下次启动应用程序时,我可以使用 checkPermissions() 并确认已授予权限。但是如果没有设备令牌,就不可能向设备发送推送通知。我做错了什么?

另一件需要注意的事情是,在模拟器上 onRegister 函数未启动,您必须使用真实设备。

万一有人遇到与我类似的问题,那是在真实的设备上,关键是注册事件,然后专门调用 PushNotificationIOS.requestPermissions(); 注册事件后。

Xcode部分怎么样?

您应该在AppDelegate文件上导入TCTPushNotification

#import <React/RCTPushNotificationManager.h>

并实现以下代码以启用 notification 和 register 在应用程序中

    // Required to register for notifications
 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
 {
  [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
 }
 // Required for the register event.
 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
 {
  [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
 }
 // Required for the notification event. You must call the completion handler after handling the remote notification.
 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
                                                        fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
 {
   [RCTPushNotificationManager didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
 }
 // Required for the registrationError event.
 - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
 {
  [RCTPushNotificationManager didFailToRegisterForRemoteNotificationsWithError:error];
 }
 // Required for the localNotification event.
 - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
 {
  [RCTPushNotificationManager didReceiveLocalNotification:notification];
 }
