iOS10全新推送功能的實現

從iOS8.0開始推送功能的實現在不斷改變，功能也在不斷增加，iOS10又出來了一個推送插件的開發（見最後圖），廢話不多說直接上代碼：

在開始之前需要打開一個推送開關,不然無法獲取deviceToken,老項目或者出現deviceToken無效的情況：如圖：

打開後會生成entitlements文件，需要有APS Environment

或許還應該打開這個

#import <UserNotifications/UserNotifications.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    /* APP未啓動，點擊推送消息的情況下 iOS10遺棄UIApplicationLaunchOptionsLocalNotificationKey，使用代理UNUserNotificationCenterDelegate方法didReceiveNotificationResponse:withCompletionHandler:獲取本地推送
     */
//    NSDictionary *localUserInfo = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];
//    if (localUserInfo) {
//        NSLog(@"localUserInfo:%@",localUserInfo);
//        //APP未啓動，點擊推送消息
//    }
    NSDictionary *remoteUserInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
    if (remoteUserInfo) {
        NSLog(@"remoteUserInfo:%@",remoteUserInfo);
        //APP未啓動，點擊推送消息，iOS10下還是跟以前一樣在此獲取
    }
    [self registerNotification];
    return YES;
}

註冊推送方法的改變：

新增庫 #import <UserNotifications/UserNotifications.h>  推送單列UNUserNotificationCenter 等API

- (void)registerNotification{
    /*
     identifier：行爲標識符，用於調用代理方法時識別是哪種行爲。
     title：行爲名稱。
     UIUserNotificationActivationMode：即行爲是否打開APP。
     authenticationRequired：是否需要解鎖。
     destructive：這個決定按鈕顯示顏色，YES的話按鈕會是紅色。
     behavior：點擊按鈕文字輸入，是否彈出鍵盤
     */
    UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"策略1行爲1" options:UNNotificationActionOptionForeground];
    /*iOS9實現方法
    UIMutableUserNotificationAction * action1 = [[UIMutableUserNotificationAction alloc] init];
    action1.identifier = @"action1";
    action1.title=@"策略1行爲1";
    action1.activationMode = UIUserNotificationActivationModeForeground;
    action1.destructive = YES;
     */
    
    UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action2" title:@"策略1行爲2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"textInputButtonTitle" textInputPlaceholder:@"textInputPlaceholder"];
    /*iOS9實現方法
        UIMutableUserNotificationAction * action2 = [[UIMutableUserNotificationAction alloc] init];
        action2.identifier = @"action2";
        action2.title=@"策略1行爲2";
        action2.activationMode = UIUserNotificationActivationModeBackground;
        action2.authenticationRequired = NO;
        action2.destructive = NO;
        action2.behavior = UIUserNotificationActionBehaviorTextInput;//點擊按鈕文字輸入，是否彈出鍵盤
    */
    
    UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"Category1" actions:@[action2,action1]  intentIdentifiers:@[@"action1",@"action2"] options:UNNotificationCategoryOptionCustomDismissAction];
    //        UIMutableUserNotificationCategory * category1 = [[UIMutableUserNotificationCategory alloc] init];
    //        category1.identifier = @"Category1";
    //        [category1 setActions:@[action2,action1] forContext:(UIUserNotificationActionContextDefault)];
    
    UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action3" title:@"策略2行爲1" options:UNNotificationActionOptionForeground];
    //        UIMutableUserNotificationAction * action3 = [[UIMutableUserNotificationAction alloc] init];
    //        action3.identifier = @"action3";
    //        action3.title=@"策略2行爲1";
    //        action3.activationMode = UIUserNotificationActivationModeForeground;
    //        action3.destructive = YES;
    
    UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action4" title:@"策略2行爲2" options:UNNotificationActionOptionForeground];
    //        UIMutableUserNotificationAction * action4 = [[UIMutableUserNotificationAction alloc] init];
    //        action4.identifier = @"action4";
    //        action4.title=@"策略2行爲2";
    //        action4.activationMode = UIUserNotificationActivationModeBackground;
    //        action4.authenticationRequired = NO;
    //        action4.destructive = NO;
    
    UNNotificationCategory *category2 = [UNNotificationCategory categoryWithIdentifier:@"Category2" actions:@[action3,action4]  intentIdentifiers:@[@"action3",@"action4"] options:UNNotificationCategoryOptionCustomDismissAction];
    //        UIMutableUserNotificationCategory * category2 = [[UIMutableUserNotificationCategory alloc] init];
    //        category2.identifier = @"Category2";
    //        [category2 setActions:@[action4,action3] forContext:(UIUserNotificationActionContextDefault)];
    
    
    [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1,category2, nil]];
    [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
        NSLog(@"completionHandler");
    }];
    /*iOS9實現方法
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObjects: category1,category2, nil]];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    */
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    
    
    [UNUserNotificationCenter currentNotificationCenter].delegate = self;
}

代理方法的改變：

一些本地和遠程推送的回調放在了同一個代理方法

#pragma mark -

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED{
    NSLog(@"didRegisterUserNotificationSettings");

                                stringByReplacingOccurrencesOfString:@">" withString:@""]
                               stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"deviceTokenSt:%@",deviceTokenSt);

    NSLog(@"willPresentNotification:%@",notification.request.content.title);
    
    // 這裏真實需要處理交互的地方
    // 獲取通知所帶的數據
    NSString *notMess = [notification.request.content.userInfo objectForKey:@"aps"];
    
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    //在沒有啓動本App時，收到服務器推送消息，下拉消息會有快捷回覆的按鈕，點擊按鈕後調用的方法，根據identifier來判斷點擊的哪個按鈕
    NSString *notMess = [response.notification.request.content.userInfo objectForKey:@"aps"];
    NSLog(@"didReceiveNotificationResponse:%@",response.notification.request.content.title);
//    response.notification.request.identifier
}

//遠程推送APP在前臺
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
    NSLog(@"didReceiveRemoteNotification:%@",userInfo);
}

/*

/*

}

    NSLog(@"%@----%@",identifier,notification);
    completionHandler();//處理完消息，最後一定要調用這個代碼塊
}
*/

還有推送插件開發: 類似iOS tody widget插件開發

   

這裏我們要注意一定要有"mutable-content": "1",以及一定要有Alert的字段，否則可能會攔截通知失敗。（蘋果文檔說的）。除此之外，我們還可以添加自定義字段，比如，圖片地址，圖片類型
{
    "aps": {
        "alert": "message.",
        "badge": 1,
        "sound": "default",
        "mutable-content": "1",
        "imageAbsoluteString": "http://xxxx"

    }
}
