iOS10 关于推送-b

最近在研究iOS10关于推送的新特性, 相比之前确实做了很大的改变,总结起来主要是以下几点:

  1. 推送内容更加丰富,由之前的alert 到现在的title, subtitle, body
  2. 推送统一由trigger触发
  3. 可以为推送增加附件,如图片、音频、视频,这就使推送内容更加丰富多彩
  4. 可以方便的更新推送内容

import 新框架

注册推送

在设置通知的时候,需要先进行注册,获取授权 
iOS10 所有通知都是通过UNUserNotificationCenter来管理,包括远程通知和本地通知

   //iOS8以下   [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];   //iOS8 - iOS10   [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeSound | UIUserNotificationTypeBadge categories:nil]];   //iOS10    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];    [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {    }

获取用户设置

iOS10 提供了获取用户授权相关设置信息的接口getNotificationSettingsWithCompletionHandler: , 回调带有一个UNNotificationSettings对象,它具有以下属性,可以准确获取各种授权信息

authorizationStatussoundSetting badgeSetting alertSetting notificationCenterSetting lockScreenSetting carPlaySettingalertStyle

像下面的方法,点击allow

    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];    [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {          if (granted) {                //点击允许                NSLog(@"注册通知成功");                [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {                NSLog(@"%@", settings);                }];            } else {                //点击不允许                NSLog(@"注册通知失败");            }        }];打印信息:   *<UNNotificationSettings: 0x174090a90; authorizationStatus: Authorized, notificationCenterSetting: Enabled, soundSetting: Enabled, badgeSetting: Enabled, lockScreenSetting: Enabled, alertSetting: NotSupported, carPlaySetting: Enabled, alertStyle: Banner>*

注册APNS, 获取token

iOS10, 注册APNS和获取token的方法还和之前一样 
在application: didFinishLaunchingWithOptions:调用 registerForRemoteNotifications方法

[[UIApplication sharedApplication] registerForRemoteNotifications];

在代理方法application: didRegisterForRemoteNotificationsWithDeviceToken:中获取token

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken NS_AVAILABLE_IOS(3_0){        NSLog(@"deviceToken:%@",deviceToken);    }- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error NS_AVAILABLE_IOS(3_0){        NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@",error);    }

设置处理通知的action 和 category

在iOS8以前是没有category这个属性的; 
在iOS8注册推送,获取授权的时候,可以一并设置category, 注册的方法直接带有这个参数; 
在iOS10, 需要调用一个方法setNotificationCategories:来为管理推送的UNUserNotificationCenter实例设置category, category又可以对应设置action;

//设置category//UNNotificationActionOptionAuthenticationRequired 需要解锁//UNNotificationActionOptionDestructive  显示为红色//UNNotificationActionOptionForeground   点击打开appUNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"策略1行为1" options:UNNotificationActionOptionForeground]; UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action2" title:@"策略1行为2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"comment" textInputPlaceholder:@"reply"]; //UNNotificationCategoryOptionNone //UNNotificationCategoryOptionCustomDismissAction  清除通知被触发会走通知的代理方法 //UNNotificationCategoryOptionAllowInCarPlay       适用于行车模式UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"category1" actions:@[action2,action1]  minimalActions:@[action2,action1] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action3" title:@"策略2行为1" options:UNNotificationActionOptionForeground];UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action4" title:@"策略2行为2" options:UNNotificationActionOptionForeground];UNNotificationCategory *category2 = [UNNotificationCategory categoryWithIdentifier:@"category2" actions:@[action3,action4]  minimalActions:@[action3,action4] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];[[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1,category2, nil]];

设置通知内容

因为iOS10远程通知与本地通知统一起来了,通知内容属性是一致的,不过远程推送就需要在payload进行具体设置了,下面以本地通知为例,介绍关于UNNotificationContent的内容 
官网上明确说明了,我们是不能直接创建UNNotificationContent的实例的, 如果我们需要自己去配置内容的各个属性,我们需要用到UNMutableNotificationContent 
看一下它的一些属性:

attachments          //附件badge                //徽标body                 //推送内容bodycategoryIdentifier   //category标识launchImageName      //点击通知进入应用的启动图sound               //声音subtitle            //推送内容子标题title               //推送内容标题userInfo           //远程通知内容UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];    content.title = @"Test";    content.subtitle = @"1234567890";    content.body = @"Copyright © 2016年 jpush. All rights reserved.";    content.badge = @1;    NSError *error = nil;    NSString *path = [[NSBundle mainBundle] pathForResource:@"718835727" ofType:@"png"];    UNNotificationAttachment *att = [UNNotificationAttachment attachmentWithIdentifier:@"att1" URL:[NSURL fileURLWithPath:path] options:nil error:&error];    if (error) {        NSLog(@"attachment error %@", error);    }    content.attachments = @[att];    content.categoryIdentifier = @"category1”;  //这里设置category1, 是与之前设置的category对应    content.launchImageName = @"1-Eb_0OvtcxJXHZ7-IOoBsaQ";UNNotificationSound *sound = [UNNotificationSound defaultSound];content.sound = sound;

通知触发器

UNNotificationTrigger 
iOS 10触发器有4种

  • UNPushNotificationTrigger 触发APNS服务,系统自动设置(这是区分本地通知和远程通知的标识)
  • UNTimeIntervalNotificationTrigger 一段时间后触发
  • UNCalendarNotificationTrigger 指定日期触发
  • UNLocationNotificationTrigger 根据位置触发,支持进入某地或者离开某地或者都有

    //十秒后UNTimeIntervalNotificationTrigger *trigger1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];//每周日早上8:00NSDateComponents *component = [[NSDateComponents alloc] init];component.weekday = 1;component.hour = 8;UNCalendarNotificationTrigger *trigger2 = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:component repeats:YES];//圆形区域,进入时候进行通知CLLocationCoordinate2D cen = CLLocationCoordinate2DMake(80.335400, -90.009201);CLCircularRegion *region = [[CLCircularRegion alloc] initWithCenter:cen                                                             radius:500.0 identifier:@“center"];region.notifyOnEntry = YES; //进入的时候region.notifyOnExit = NO;   //出去的时候UNLocationNotificationTrigger *trigger3 = [UNLocationNotificationTrigger    triggerWithRegion:region repeats:NO];

添加通知 / 更新通知

  1. 创建一个UNNotificationRequest类的实例,一定要为它设置identifier, 在后面的查找,更新, 删除通知,这个标识是可以用来区分这个通知与其他通知
  2. 把request加到UNUserNotificationCenter, 并设置触发器,等待触发
  3. 如果另一个request具有和之前request相同的标识,不同的内容, 可以达到更新通知的目的

       NSString *requestIdentifer = @"TestRequest";   UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestIdentifer content:content trigger:trigger1];   //把通知加到UNUserNotificationCenter, 到指定触发点会被触发   [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {   }]; //在另外需要更新通知的地方UNMutableNotificationContent *newContent = [[UNMutableNotificationContent alloc] init];newContent.title = @"Update";newContent.subtitle = @"XXXXXXXXX";newContent.body = @"Copyright © 2016年 jpush. All rights reserved.";UNTimeIntervalNotificationTrigger *trigger1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:3 repeats:NO]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"TestRequest" content:newContent trigger:trigger1];[[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {}];

获取和删除通知

这里通知是有两种状态

  • Pending 等待触发的通知
  • Delivered 已经触发展示在通知中心的通知

    //获取未触发的通知[[UNUserNotificationCenter currentNotificationCenter] getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {    NSLog(@"pending: %@", requests);}];//获取通知中心列表的通知[[UNUserNotificationCenter currentNotificationCenter] getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) {    NSLog(@"Delivered: %@", notifications);}]; //清除某一个未触发的通知 [[UNUserNotificationCenter currentNotificationCenter] removePendingNotificationRequestsWithIdentifiers:@[@"TestRequest1"]];  //清除某一个通知中心的通知 [[UNUserNotificationCenter currentNotificationCenter] removeDeliveredNotificationsWithIdentifiers:@[@"TestRequest2"]];  //对应的删除所有通知[[UNUserNotificationCenter currentNotificationCenter] removeAllPendingNotificationRequests];[[UNUserNotificationCenter currentNotificationCenter] removeAllDeliveredNotifications];

delegate

<UNUserNotificationCenterDelegate>

iOS10收到通知不再是在application: didReceiveRemoteNotification:方法去处理, iOS10推出新的代理方法,接收和处理各类通知(本地或者远程)

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {    //应用在前台收到通知    NSLog(@"========%@", notification);}- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {    //点击通知进入应用    NSLog(@"response:%@", response);}

最后
