iOS常用通知

1、本地推送通知:（Local Notification）:
??不需要聯(lián)網(wǎng)就可以發(fā)出的通知, 常用于提醒用戶完成一些任務(wù)锹杈，如：鬧鐘撵孤，日歷待辦事項(xiàng)提醒，備注等等;
2竭望、遠(yuǎn)程推送通知:（Remote Notification）
??從遠(yuǎn)程服務(wù)器(APNs)推送給客戶端的通知(需要聯(lián)網(wǎng)), 模擬器無(wú)法調(diào)試遠(yuǎn)程推送;
??常用于解決獲取傳統(tǒng)數(shù)據(jù)的局限性邪码，能讓數(shù)據(jù)實(shí)時(shí)更新, 在聯(lián)網(wǎng)的情況下, 蘋果設(shè)備都會(huì)與APNs建立長(zhǎng)連接, 因此能保證數(shù)據(jù)傳輸速度快及保證數(shù)據(jù)的實(shí)時(shí)性...

本篇只介紹本地推送通知:

通知的授權(quán)與注冊(cè): (分iOS10.0 以后 與 之前)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 通知的授權(quán)檢查
    [self checkNotificationAuthorization];
        
    // 本地通知 + App未存活 (iOS 10.0以前)
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification.userInfo) {
        //  處理收到的通知
    }
    return YES;
}

/**
 檢查本地通知的授權(quán)
 */
- (void)checkNotificationAuthorization {
    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter * center = [UNUserNotificationCenter currentNotificationCenter];
        // 這兩個(gè)必須要寫(xiě)在上面  每次程序重新打開(kāi)時(shí)都得設(shè)置一遍...
        center.delegate = self;
        //添加category: iOS 10.0以后
        [center setNotificationCategories:[self createNotificationCategoryActionsForNewVersion]];
        
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
            if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined) {  // 判斷是否是未選擇授權(quán)狀態(tài)
                // 若未授權(quán), 則請(qǐng)求授權(quán)
                [center requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
                        if (granted) {
                              NSLog(@"授權(quán)開(kāi)啟成功");
                        } else {
                              NSLog(@"授權(quán)開(kāi)啟失敗");
                        }
                }];
            }
        }];
    } else {
        //添加category: iOS 8.0以后
        UIUserNotificationCategory * category = [self adduserNotificationCategory];

        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    }
}

添加 category (即在通知欄重壓時(shí)設(shè)置其按鈕)

通知欄的通知

//添加category: iOS 10.0以后
-(NSSet *)createNotificationCategoryActionsForNewVersion{
    //注冊(cè)本地通知用到的Action
    //進(jìn)入app按鈕
    UNNotificationAction * localAction = [UNNotificationAction actionWithIdentifier:kCategoryActionIdentifierOpen title:@"查看通知" options:UNNotificationActionOptionForeground];
    
    //取消按鈕
    UNNotificationAction *localCancel = [UNNotificationAction actionWithIdentifier:kCategoryActionIdentifierCancel title:@"忽略" options:UNNotificationActionOptionDestructive];
    //將這些action帶入category
    UNNotificationCategory *localCategory = [UNNotificationCategory categoryWithIdentifier:kUNCategoryIdentifier actions:@[localAction,localCancel] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
    
    return [NSSet setWithObjects:localCategory,nil];
}

//添加category: iOS 8.0以后
- (UIMutableUserNotificationCategory *)adduserNotificationCategory {
    //UIMutableUserNotificationAction用來(lái)添加自定義按鈕
    UIMutableUserNotificationAction * responseAction = [[UIMutableUserNotificationAction alloc] init];
    responseAction.identifier = kCategoryActionIdentifierOpen;
    responseAction.title = @"查看通知";
    responseAction.activationMode = UIUserNotificationActivationModeForeground; //點(diǎn)擊的時(shí)候啟動(dòng)程序
    responseAction.authenticationRequired = YES;//需要解鎖權(quán)限
    
    UIMutableUserNotificationAction *deleteAction = [[UIMutableUserNotificationAction alloc] init];
    deleteAction.identifier = kCategoryActionIdentifierCancel;
    deleteAction.title = @"忽略";
    deleteAction.activationMode = UIUserNotificationActivationModeBackground; //點(diǎn)擊的時(shí)候不啟動(dòng)程序，后臺(tái)處理
    deleteAction.destructive = YES; //YES為紅色咬清，NO為藍(lán)色
    
    UIMutableUserNotificationCategory *category = [[UIMutableUserNotificationCategory alloc] init];
    category.identifier = kUNCategoryIdentifier;//用于將該 category 標(biāo)識(shí)的同時(shí)闭专，那一個(gè) notification 實(shí)例需要使用這個(gè) category 的 actions 也是傳入這個(gè)值給 notification 的。
    
    //UIUserNotificationActionContextDefault:默認(rèn)添加可以添加兩個(gè)自定義按鈕
    //UIUserNotificationActionContextMinimal:四個(gè)自定義按鈕
    [category setActions:@[responseAction, deleteAction] forContext:UIUserNotificationActionContextDefault];
    
    return category;
}

添加通知
??這里是點(diǎn)擊一個(gè)按鈕事件來(lái)添加通知的:

- (IBAction)addLocalNotification:(UIButton *)sender {
    NSDictionary * dict = @{@"businessId": @"kLocalNotificationTest",@"title": @"本地通知測(cè)試",@"memo": @"通知發(fā)送成功", @"startTime": @"2019-10-28 10:10:10"};

    NSArray * arr = @[dict, dict1];
    // 添加兩個(gè)通知
    for (NSDictionary * dataDic in arr) {
        NSData * data = [NSJSONSerialization dataWithJSONObject:dataDic options:NSJSONWritingPrettyPrinted error:nil];
        NSString * string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        [self addLocalNotificationWithData:string];
    }
}

    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter * center = [UNUserNotificationCenter currentNotificationCenter];
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
            if (settings.authorizationStatus == UNAuthorizationStatusDenied) {
                NSLog(@"用戶未授權(quán)");
                return;
            }
            
            UNMutableNotificationContent * content = [[UNMutableNotificationContent alloc] init];
            self.badgeNum++;

            [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
                if (error) {
                    NSLog(@"添加本地通知報(bào)錯(cuò): %@", error);
                }
            }];
        }];
    } else {
        if ([[UIApplication sharedApplication] currentUserNotificationSettings].types == UIUserNotificationTypeNone) {
            NSLog(@"用戶未授權(quán)");
            return;
        }
        
        UILocalNotification * notification = [[UILocalNotification alloc] init];
        notification.timeZone = [NSTimeZone defaultTimeZone];
        notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:5.f];
        
        notification.alertTitle = dict[@"title"];
        notification.alertBody = dict[@"memo"];
        self.badgeNum++;
        notification.applicationIconBadgeNumber = self.badgeNum;

        notification.category = kUNCategoryIdentifier;
        
        [[UIApplication sharedApplication] scheduleLocalNotification:notification];
    }
}

通知的回調(diào)處理:

??iOS10.0 后是通知代理來(lái)回調(diào)的 UNUserNotificationCenterDelegate

// App在前臺(tái)獲取通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler  API_AVAILABLE(ios(10.0)){
    completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound);
}

// 點(diǎn)擊通知進(jìn)入App
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler  API_AVAILABLE(ios(10.0)){
    completionHandler();
    
    NSDictionary * userInfo = response.notification.request.content.userInfo;
    if(userInfo[@"type"] && [userInfo[@"type"] isEqualToString:kNotificationScheduleType]) {
        if([response.actionIdentifier isEqualToString:kCategoryActionIdentifierCancel] || [response.actionIdentifier isEqualToString:UNNotificationDismissActionIdentifier]) {
            // 通知欄點(diǎn)擊 忽略 或 清除 時(shí)的回調(diào)
        } else {
            //  點(diǎn)擊 打開(kāi) 或 查看 時(shí)的回調(diào)
        }
    }
}

??iOS10.0 以前的通知回調(diào):

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 本地通知 + App未存活
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification.userInfo) {
        // 處理回調(diào)回來(lái)的通知事件
    }
    return YES;
}
// APP在前臺(tái)運(yùn)行中收到 本地通知 時(shí)調(diào)用, 以及App 處于后臺(tái)掛起（suspended）狀態(tài)旧烧，但未 terminated 時(shí)喻圃，點(diǎn)擊通知啟動(dòng)都是這個(gè)方法進(jìn)行響應(yīng)
// 即 App 存活
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    
}

//調(diào)用過(guò)用戶注冊(cè)通知方法之后執(zhí)行（也就是調(diào)用完registerUserNotificationSettings:方法之后執(zhí)行）
-(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    
}

// APP 將要進(jìn)入前臺(tái)時(shí)調(diào)用
- (void)applicationWillEnterForeground:(UIApplication *)application {
    //  設(shè)置App圖標(biāo)通知數(shù)量顯示
}

//iOS 8 ~ 9 ，當(dāng)點(diǎn)擊本地通知自定義的響應(yīng)按鈕(action btn)時(shí)粪滤，根據(jù)按鈕的 activeMode 模式斧拍，回調(diào)以下方法
//1. ActivationModeForeground 的 action , 會(huì)啟動(dòng) App 同時(shí)回調(diào)方法
//2. ActivationModeBackground 的 action 不啟動(dòng) App 讓 App 在 background 下回調(diào)方法
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler {
    
    if ([identifier isEqualToString:@"kCategoryActionIdentifierOpen"]) {
        //ActivationModeForeground 的 action , 啟動(dòng) App 讓 App 在 Foreground 下響應(yīng)
        
    } else {
        //ActivationModeBackground 的 action 不啟動(dòng) App 讓 App 在 background 下響應(yīng)
        NSLog(@"%s  -- %@  -- identifier %@ --- thread %@", __func__, notification, identifier, [NSThread currentThread]);
        
//        //下面代碼用于測(cè)試，退出 App 后接收到 本地通知時(shí)杖小，點(diǎn)擊后臺(tái)action時(shí)是否執(zhí)行了這個(gè)響應(yīng)方法肆汹。實(shí)測(cè)執(zhí)行了的
//        [[NSUserDefaults standardUserDefaults] setObject:@"ActivationModeBackground 的 action 不啟動(dòng) App 讓 App 在 background 下響應(yīng)" forKey:@"IGNOREKEY"];
//        [[NSUserDefaults standardUserDefaults] synchronize];
        
    }
    completionHandler(); //根據(jù)Action btn 的 identifier 處理自定義事件后應(yīng)該馬上調(diào)用 completionHandler block,如果調(diào)用 completionHandler block 失敗的話，App 會(huì)立即 terminated予权。
}
