最近在研究iOS10關于推送的新特性， 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，可以準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，可以一并設置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appUNNotificationAction *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 適用于行車模式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，介紹關于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”; //這里設置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 一段時間后觸發
•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];//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, 在后面的查找，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， 并設置觸發器，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
這里通知是有兩種狀態
•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 { //應用在前臺收到通知 NSLog(@"========%@", notification);}- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler { //點擊通知進入應用 NSLog(@"response:%@", response);}最后
下一篇文章繼續介紹關于富媒體推送的 UNNotificationServiceExtension 和 Notification content extension， 未完待續。。。
