iOS开发本地推送（iOS10）UNUserNotificationCenter

1、简介

　　iOS10之后苹果对推送进行了封装，UNUserNotificationCenter就这样产生了。简单介绍本地推送的使用UserNotifications官方文档说明！

 

2、简单使用UNUserNotificationCenter

　　一、创建UNUserNotificationCenter，设置推送模式和代理！

        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert|UNAuthorizationOptionSound|UNAuthorizationOptionBadge)
                              completionHandler:^(BOOL granted, NSError * _Nullable error) {
                                  if (!error) {
                                      NSLog(@"succeeded!");
                                  }
                              }];
        center.delegate = self;

　　二、设置推送内容

        UNMutableNotificationContent *content = [UNMutableNotificationContent new];
        content.title = @"推送中心标题";
        content.subtitle = @"副标题";
        content.body  = @"这是UNUserNotificationCenter信息中心";
        content.badge = @20;
        content.categoryIdentifier = @"categoryIdentifier";
        
//        需要解锁显示，红色文字。点击不会进app。
//        UNNotificationActionOptionAuthenticationRequired = (1 << 0),
//
//        黑色文字。点击不会进app。
//        UNNotificationActionOptionDestructive = (1 << 1),
//
//        黑色文字。点击会进app。
//        UNNotificationActionOptionForeground = (1 << 2),
        
        UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"enterApp"
                                                                            title:@"进入应用"
                                                                          options:UNNotificationActionOptionForeground];
        UNNotificationAction *clearAction = [UNNotificationAction actionWithIdentifier:@"destructive"
                                                                                 title:@"忽略2"
                                                                               options:UNNotificationActionOptionDestructive];
        UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"categoryIdentifier"
                                                                                  actions:@[action,clearAction]
                                                                        intentIdentifiers:@[requestID]
                                                                                  options:UNNotificationCategoryOptionNone];
        [center setNotificationCategories:[NSSet setWithObject:category]];

　　三、设置推送方式

        UNTimeIntervalNotificationTrigger *timeTrigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];
        UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestID content:content trigger:timeTrigger];

　　trigger的其它用法：

        //1分钟后提醒
        UNTimeIntervalNotificationTrigger *trigger1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:NO];
        
        //每小时重复 1 次
        UNTimeIntervalNotificationTrigger *trigger2 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:3600 repeats:YES];
        
        //周日早8点
        NSDateComponents *components = [[NSDateComponents alloc] init];
        components.weekday = 1;
        components.hour = 8;
        UNCalendarNotificationTrigger *trigger3 = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];
        
        //#import <CoreLocation/CoreLocation.h>
        CLRegion *region = [[CLRegion alloc] init];
        UNLocationNotificationTrigger *trigger4 = [UNLocationNotificationTrigger triggerWithRegion:region repeats:NO];

 

　　四、添加推送request

        [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { }];

 

3、UNUserNotificationCenter的Delegate

//将要推送
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
    NSLog(@"----------willPresentNotification");
}
//已经完成推送
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler{
    NSLog(@"============didReceiveNotificationResponse");
    NSString *categoryID = response.notification.request.content.categoryIdentifier;
    if ([categoryID isEqualToString:@"categoryIdentifier"]) {
        if ([response.actionIdentifier isEqualToString:@"enterApp"]) {
            if (@available(iOS 10.0, *)) {
                
            } else {
                // Fallback on earlier versions
            }
        }else{
            NSLog(@"No======");
        }
    }
    completionHandler();
}

 

4、移除推送

        [center removePendingNotificationRequestsWithIdentifiers:@[requestID]];
        [center removeAllDeliveredNotifications];

附录：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    if (@available(iOS 10.0, *)) {
        //第一步：获取推送通知中心
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert|UNAuthorizationOptionSound|UNAuthorizationOptionBadge)
                              completionHandler:^(BOOL granted, NSError * _Nullable error) {
                                  if (!error) {
                                      NSLog(@"succeeded!");
                                  }
                              }];
        center.delegate = self;
        
        //第二步：设置推送内容
        UNMutableNotificationContent *content = [UNMutableNotificationContent new];
        content.title = @"推送中心标题";
        content.subtitle = @"副标题";
        content.body  = @"这是UNUserNotificationCenter信息中心";
        content.badge = @20;
        content.categoryIdentifier = @"categoryIdentifier";
        
        
//        需要解锁显示，红色文字。点击不会进app。
//        UNNotificationActionOptionAuthenticationRequired = (1 << 0),
//
//        黑色文字。点击不会进app。
//        UNNotificationActionOptionDestructive = (1 << 1),
//
//        黑色文字。点击会进app。
//        UNNotificationActionOptionForeground = (1 << 2),
        

        UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"enterApp"
                                                                            title:@"进入应用"
                                                                          options:UNNotificationActionOptionForeground];
        UNNotificationAction *clearAction = [UNNotificationAction actionWithIdentifier:@"destructive"
                                                                                 title:@"忽略2"
                                                                               options:UNNotificationActionOptionDestructive];
        UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"categoryIdentifier"
                                                                                  actions:@[action,clearAction]
                                                                        intentIdentifiers:@[requestID]
                                                                                  options:UNNotificationCategoryOptionNone];
        [center setNotificationCategories:[NSSet setWithObject:category]];

        //第三步：设置推送方式
        UNTimeIntervalNotificationTrigger *timeTrigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];
        UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestID content:content trigger:timeTrigger];
        
        //第四步：添加推送request
        [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
            
        }];
        
        
        [center removePendingNotificationRequestsWithIdentifiers:@[requestID]];
        [center removeAllDeliveredNotifications];
//        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
//            NSLog(@"settings===%@",settings);
//        }];
    } else {
    }
    return YES;
}
