PushNotificationIOS

本模块帮助你处理应用的推送通知,包括权限控制以及应用图标上的角标数(未读消息数)。

要使用推送通知功能,首先在苹果后台配置推送通知服务并且准备好服务端的系统。

首先请手动链接PushNotificationIOS的库(以下操作如果不熟悉,请自行补习Xcode的使用教程):

  • node_modules/react-native/Libraries/PushNotificationIOS/RCTPushNotification.xcodeproj文件拖到Xcode界面中
  • 在Xcode的Link Binary With Libraries中添加libRCTPushNotification.a

然后你需要在AppDelegate中启用推送通知的支持以及注册相应的事件。

AppDelegate.m开头:


#import <React/RCTPushNotificationManager.h>

然后在AppDelegate实现中添加如下的代码:

 // 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];
 }

getDeliveredNotifications()

PushNotificationIOS.getDeliveredNotifications(callback);

Provides you with a list of the app’s notifications that are still displayed in Notification Center

参数:

A delivered notification is an object containing:

  • identifier : The identifier of this notification.
  • title : The title of this notification.
  • body : The body of this notification.
  • category : The category of this notification, if has one.
  • userInfo : An optional object containing additional notification data.

removeDeliveredNotifications()

PushNotificationIOS.removeDeliveredNotifications(identifiers);

Removes the specified notifications from Notification Center

参数:

名称类型必填说明
identifiersarrayArray of notification identifiers.

setApplicationIconBadgeNumber()

PushNotificationIOS.setApplicationIconBadgeNumber(number);

Sets the badge number for the app icon on the home screen

参数:

名称类型必填说明
numbernumberBadge number for the app icon.

getApplicationIconBadgeNumber()

PushNotificationIOS.getApplicationIconBadgeNumber(callback);

Gets the current badge number for the app icon on the home screen

参数:

名称类型必填说明
callbackfunctionA function that will be passed the current badge number.

cancelLocalNotifications()

PushNotificationIOS.cancelLocalNotifications(userInfo);

Cancel local notifications.

Optionally restricts the set of canceled notifications to those notifications whose userInfo fields match the corresponding fields in the userInfo argument.

参数:

名称类型必填说明
userInfoobject

getScheduledLocalNotifications()

PushNotificationIOS.getScheduledLocalNotifications(callback);

Gets the local notifications that are currently scheduled.

参数:

名称类型必填说明
callbackfunctionA function that will be passed an array of objects describing local notifications.

addEventListener()

PushNotificationIOS.addEventListener(type, handler);

Attaches a listener to remote or local notification events while the app is running in the foreground or the background.

参数:

名称类型必填说明
typestringEvent type.
handlerfunctionListener.

Valid events are:

  • notification : Fired when a remote notification is received. The handler will be invoked with an instance of PushNotificationIOS.
  • localNotification : Fired when a local notification is received. The handler will be invoked with an instance of PushNotificationIOS.
  • register: Fired when the user registers for remote notifications. The handler will be invoked with a hex string representing the deviceToken.
  • registrationError: Fired when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. The handler will be invoked with {message: string, code: number, details: any}.

removeEventListener()

PushNotificationIOS.removeEventListener(type, handler);

Removes the event listener. Do this in componentWillUnmount to prevent memory leaks

参数:

typestringEvent type.
handlerfunctionListener.

requestPermissions()

PushNotificationIOS.requestPermissions([permissions]);

Requests notification permissions from iOS, prompting the user's dialog box. By default, it will request all notification permissions, but a subset of these can be requested by passing a map of requested permissions. The following permissions are supported:

  • alert
  • badge
  • sound

If a map is provided to the method, only the permissions with truthy values will be requested.

This method returns a promise that will resolve when the user accepts, rejects, or if the permissions were previously rejected. The promise resolves to the current state of the permission.

参数:

名称类型必填说明
permissionsarrayalert, badge, or sound

abandonPermissions()

PushNotificationIOS.abandonPermissions();

Unregister for all remote notifications received via Apple Push Notification service.

You should call this method in rare circumstances only, such as when a new version of the app removes support for all types of remote notifications. Users can temporarily prevent apps from receiving remote notifications through the Notifications section of the Settings app. Apps unregistered through this method can always re-register.


checkPermissions()

PushNotificationIOS.checkPermissions(callback);

See what push permissions are currently enabled.

参数:

名称类型必填说明
callbackfunction看下面的说明

callback will be invoked with a permissions object:

  • alert :boolean
  • badge :boolean
  • sound :boolean

getInitialNotification()

PushNotificationIOS.getInitialNotification();

This method returns a promise. If the app was launched by a push notification, this promise resolves to an object of type PushNotificationIOS. Otherwise, it resolves to null.


constructor()


constructor(nativeNotif);

You will never need to instantiate PushNotificationIOS yourself. Listening to the notification event and invoking getInitialNotification is sufficient.


finish()

finish(fetchResult);

This method is available for remote notifications that have been received via: application:didReceiveRemoteNotification:fetchCompletionHandler:https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/#//apple_ref/occ/intfm/UIApplicationDelegate/application:didReceiveRemoteNotification:fetchCompletionHandler:

Call this to execute when the remote notification handling is complete. When calling this block, pass in the fetch result value that best describes the results of your operation. You must call this handler and should do so as soon as possible. For a list of possible values, see PushNotificationIOS.FetchResult.

If you do not call this method your background remote notifications could be throttled, to read more about it see the above documentation link.
