iOS10 關於推送-b

標籤：

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，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 新架構

添加新的架構 UserNotifications.framework 

#import <UserNotifications/UserNotifications.h>

註冊推送

在設定通知的時候，需要先進行註冊，擷取授權 
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) {    }

擷取使用者佈建

iOS10 提供了擷取使用者授權相關設定資訊的介面getNotificationSettingsWithCompletionHandler： , 回調帶有一個UNNotificationSettings對象，它具有以下屬性，可以準確擷取各種授權資訊

authorizationStatussoundSetting badgeSetting alertSetting notificationCenterSetting lockScreenSetting carPlaySettingalertStyle

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(@"註冊通知成功");                [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {                NSLog(@"%@", settings);                }];            } else {                //點擊不允許                NSLog(@"註冊通知失敗");            }        }];列印資訊：   *<UNNotificationSettings: 0x174090a90; authorizationStatus: Authorized, notificationCenterSetting: Enabled, soundSetting: Enabled, badgeSetting: Enabled, lockScreenSetting: Enabled, alertSetting: NotSupported, carPlaySetting: Enabled, alertStyle: Banner>*

註冊APNS, 擷取token

iOS10， 註冊APNS和擷取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:中擷取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);    }

設定處理通知的action 和 category

在iOS8以前是沒有category這個屬性的; 
在iOS8註冊推送，擷取授權的時候，可以一併設定category， 註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執行個體設定category, category又可以對應設定action;

//設定category//UNNotificationActionOptionAuthenticationRequired 需要解鎖//UNNotificationActionOptionDestructive  顯示為紅色//UNNotificationActionOptionForeground   點擊開啟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]];

設定通知內容

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進行具體設定了，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，我們是不能直接建立UNNotificationContent的執行個體的， 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bodycategoryIdentifier   //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”;  //這裡設定category1， 是與之前設定的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，系統自動化佈建（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，支援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8：00NSDateComponents *component = [[NSDateComponents alloc] init];component.weekday = 1;component.hour = 8;UNCalendarNotificationTrigger *trigger2 = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:component repeats:YES];//圓形地區，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. 建立一個UNNotificationRequest類的執行個體，一定要為它設定identifier, 在後面的尋找，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， 並設定觸發器，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) {}];

擷取和刪除通知

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樞的通知

  //擷取未觸發的通知[[UNUserNotificationCenter currentNotificationCenter] getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {    NSLog(@"pending: %@", requests);}];//擷取通知中樞列表的通知[[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"]];  //清除某一個通知中樞的通知 [[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);}
