想了解iOS10 推送最新特性研究的相关内容吗,幸福小祢在本文为您仔细讲解iOS10 推送新特性的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:iOS10,推送,下面大家一起来学习吧。

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

添加新的框架 UserNotifications.framework

 

#import <UserNotifications/UserNotifications.h> 

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

authorizationStatus
soundSetting
badgeSetting
alertSetting
notificationCenterSetting
lockScreenSetting
carPlaySetting
alertStyle 

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
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app

UNNotificationAction *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body
categoryIdentifier   //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8:00
NSDateComponents *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);
}
