最近在研究iOS10關於推送的新特性， 相比之前確實做了很大的改變，總結起來主要是以下幾點：

 1.推送內容更加豐富，由之前的alert 到現在的title, subtitle, body
 2.推送統一由trigger觸發
 3.可以為推送增加附件，如圖片、音頻、視頻，這就使推送內容更加豐富多彩
 4.可以方便的更新推送內容 

import 新框架

添加新的框架 UserNotifications.framework

 

#import <UserNotifications/UserNotifications.h> 

注冊推送 

在設置通知的時候，需要先進行注冊，獲取授權
iOS10 所有通知都是通過UNUserNotificationCenter來管理，包括遠程通知和本地通知

  //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) {

  }

獲取用戶設置 

iOS10 提供了獲取用戶授權相關設置信息的接口getNotificationSettingsWithCompletionHandler： , 回調帶有一個UNNotificationSettings對象，它具有以下屬性，可以准確獲取各種授權信息

authorizationStatus
soundSetting
badgeSetting
alertSetting
notificationCenterSetting
lockScreenSetting
carPlaySetting
alertStyle 

像下面的方法，點擊allow

   UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
     if (granted) {
        //點擊允許
        NSLog(@"注冊通知成功");
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
        NSLog(@"%@", settings);
        }];
      } else {
        //點擊不允許
        NSLog(@"注冊通知失敗");
      }
    }];

打印信息：   *<UNNotificationSettings: 0x174090a90; authorizationStatus: Authorized, notificationCenterSetting: Enabled, soundSetting: Enabled, badgeSetting: Enabled, lockScreenSetting: Enabled, alertSetting: NotSupported, carPlaySetting: Enabled, alertStyle: Banner>* 

注冊APNS, 獲取token 

iOS10， 注冊APNS和獲取token的方法還和之前一樣
在application: didFinishLaunchingWithOptions:調用 registerForRemoteNotifications方法
 [[UIApplication sharedApplication] registerForRemoteNotifications]; 

在代理方法application: didRegisterForRemoteNotificationsWithDeviceToken:中獲取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);
  }
 

設置處理通知的action 和 category 

在iOS8以前是沒有category這個屬性的;
在iOS8注冊推送，獲取授權的時候，可以一並設置category， 注冊的方法直接帶有這個參數;
在iOS10， 需要調用一個方法setNotificationCategories:來為管理推送的UNUserNotificationCenter實例設置category, category又可以對應設置action;

 //設置category
//UNNotificationActionOptionAuthenticationRequired 需要解鎖
//UNNotificationActionOptionDestructive 顯示為紅色
//UNNotificationActionOptionForeground  點擊打開app

UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"策略1行為1" options:UNNotificationActionOptionForeground];

UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action2" title:@"策略1行為2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"comment" textInputPlaceholder:@"reply"];

 //UNNotificationCategoryOptionNone
 //UNNotificationCategoryOptionCustomDismissAction 清除通知被觸發會走通知的代理方法
 //UNNotificationCategoryOptionAllowInCarPlay    適用於行車模式
UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"category1" actions:@[action2,action1] minimalActions:@[action2,action1] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];

UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action3" title:@"策略2行為1" options:UNNotificationActionOptionForeground];

UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action4" title:@"策略2行為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]];
 

設置通知內容 

因為iOS10遠程通知與本地通知統一起來了，通知內容屬性是一致的，不過遠程推送就需要在payload進行具體設置了，下面以本地通知為例，介紹關於UNNotificationContent的內容
官網上明確說明了，我們是不能直接創建UNNotificationContent的實例的， 如果我們需要自己去配置內容的各個屬性，我們需要用到UNMutableNotificationContent
看一下它的一些屬性：
attachments          //附件
badge                //徽標
body                 //推送內容body
categoryIdentifier   //category標識
launchImageName      //點擊通知進入應用的啟動圖
sound               //聲音
subtitle            //推送內容子標題
title               //推送內容標題
userInfo           //遠程通知內容

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”; //這裡設置category1， 是與之前設置的category對應
  content.launchImageName = @"1-Eb_0OvtcxJXHZ7-IOoBsaQ";

UNNotificationSound *sound = [UNNotificationSound defaultSound];
content.sound = sound;

 

通知觸發器 

UNNotificationTrigger
iOS 10觸發器有4種
 •UNPushNotificationTrigger 觸發APNS服務，系統自動設置（這是區分本地通知和遠程通知的標識）
 •UNTimeIntervalNotificationTrigger 一段時間後觸發
 •UNCalendarNotificationTrigger 指定日期觸發
 •UNLocationNotificationTrigger 根據位置觸發，支持進入某地或者離開某地或者都有

 //十秒後
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];

//圓形區域，進入時候進行通知
CLLocationCoordinate2D cen = CLLocationCoordinate2DMake(80.335400, -90.009201);
CLCircularRegion *region = [[CLCircularRegion alloc] initWithCenter:cen
                               radius:500.0 identifier:@“center"];
region.notifyOnEntry = YES; //進入的時候
region.notifyOnExit = NO;  //出去的時候
UNLocationNotificationTrigger *trigger3 = [UNLocationNotificationTrigger
  triggerWithRegion:region repeats:NO];
 

添加通知 / 更新通知

 1.創建一個UNNotificationRequest類的實例，一定要為它設置identifier, 在後面的查找，更新， 刪除通知，這個標識是可以用來區分這個通知與其他通知
 2.把request加到UNUserNotificationCenter， 並設置觸發器，等待觸發
 3.
如果另一個request具有和之前request相同的標識，不同的內容， 可以達到更新通知的目的

  NSString *requestIdentifer = @"TestRequest";
  UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestIdentifer content:content trigger:trigger1];
  //把通知加到UNUserNotificationCenter, 到指定觸發點會被觸發
  [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) {

}];

 

獲取和刪除通知 

這裡通知是有兩種狀態
 •Pending 等待觸發的通知
 •Delivered 已經觸發展示在通知中心的通知

 //獲取未觸發的通知
[[UNUserNotificationCenter currentNotificationCenter] getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
  NSLog(@"pending: %@", requests);
}];

//獲取通知中心列表的通知
[[UNUserNotificationCenter currentNotificationCenter] getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) {
  NSLog(@"Delivered: %@", notifications);
}];

 //清除某一個未觸發的通知
 [[UNUserNotificationCenter currentNotificationCenter] removePendingNotificationRequestsWithIdentifiers:@[@"TestRequest1"]];
 //清除某一個通知中心的通知
 [[UNUserNotificationCenter currentNotificationCenter] removeDeliveredNotificationsWithIdentifiers:@[@"TestRequest2"]];
 //對應的刪除所有通知
[[UNUserNotificationCenter currentNotificationCenter] removeAllPendingNotificationRequests];
[[UNUserNotificationCenter currentNotificationCenter] removeAllDeliveredNotifications];

 delegate 

<UNUserNotificationCenterDelegate> 

iOS10收到通知不再是在application: didReceiveRemoteNotification:方法去處理， iOS10推出新的代理方法，接收和處理各類通知（本地或者遠程）

 - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
  //應用在前台收到通知
  NSLog(@"========%@", notification);
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
  //點擊通知進入應用
  NSLog(@"response:%@", response);
}
