1、導(dǎo)入所需的 庫(kù)

#import <UserNotifications/UserNotifications.h>

2、注冊(cè)通知，代理實(shí)現(xiàn)

// 代理
@interface AppDelegate () <UNUserNotificationCenterDelegate>

@end

// 注冊(cè)通知

- (void)registerNotification {
    UNAuthorizationOptions options = UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge;
    UNUserNotificationCenter.currentNotificationCenter.delegate = self;
    [UNUserNotificationCenter.currentNotificationCenter requestAuthorizationWithOptions:options completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (granted) {
            // 允許授權(quán)
        } else {
            // 不允許授權(quán)
        }
    }];
    
    
    // 獲取用戶對(duì)通知的設(shè)置
    // 通過settings.authorizationStatus 來處理用戶沒有打開通知授權(quán)的情況
    [UNUserNotificationCenter.currentNotificationCenter getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
        NSLog(@"%@",settings);
    }];
}

// 在前臺(tái)時(shí) 收到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
    
    completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionBadge);
}


// 點(diǎn)擊通知，從后臺(tái)進(jìn)入前臺(tái)
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler {
    NSString *identifier =  response.actionIdentifier;
    
    if ([identifier isEqualToString:@"open"]) {
        NSLog(@"打開操作");
    } else if ([identifier isEqualToString:@"close"]) {
        NSLog(@"關(guān)閉操作");
    }
    completionHandler();
}

3、添加通知、包含一些操作

- (void)addNotification {
    // 創(chuàng)建一個(gè)通知內(nèi)容
    UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
    content.badge = @1;
    content.title = @"title";
    content.subtitle = @"subtitle";
    content.body = @"body";
    content.sound = [UNNotificationSound defaultSound];
    content.categoryIdentifier = @"category";
    
    
    // 通知觸發(fā)器
    UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:false];
    // 通知請(qǐng)求
    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"noti" content:content trigger:trigger];
    //添加通知
    [UNUserNotificationCenter.currentNotificationCenter addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
        
        NSLog(@"error:%@",error);
    }];
    
    
    // 添加通知的一些操作
    UNNotificationAction *openAction = [UNNotificationAction actionWithIdentifier:@"open" title:@"打開" options:UNNotificationActionOptionForeground];
    UNNotificationAction *closeAction = [UNNotificationAction actionWithIdentifier:@"close" title:@"關(guān)閉" options:UNNotificationActionOptionDestructive];
    UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"category" actions:@[openAction, closeAction] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
        
    NSSet *sets = [NSSet setWithObject:category];
    [UNUserNotificationCenter.currentNotificationCenter setNotificationCategories:sets];
}

4、移除通知

- (void)removeNotifiation {
    // 移除 待處理的通知
    [UNUserNotificationCenter.currentNotificationCenter removePendingNotificationRequestsWithIdentifiers:@[@"noti"]];
    // 移除 已經(jīng)處理的通知
    [UNUserNotificationCenter.currentNotificationCenter removeDeliveredNotificationsWithIdentifiers:@[@"noti"]];
    
    // 移除所有的通知
    [UNUserNotificationCenter.currentNotificationCenter removeAllDeliveredNotifications];
    [UNUserNotificationCenter.currentNotificationCenter removeAllPendingNotificationRequests];
}
