iOS|iOS 本地通知实现 iOS本地通知实现

1、导入所需的库

#import

2、注册通知，代理实现

// 代理 @interface AppDelegate () @end// 注册通知- (void)registerNotification { UNAuthorizationOptions options = UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge; UNUserNotificationCenter.currentNotificationCenter.delegate = self; [UNUserNotificationCenter.currentNotificationCenter requestAuthorizationWithOptions:options completionHandler:^(BOOL granted, NSError * _Nullable error) { if (granted) { // 允许授权 } else { // 不允许授权 } }]; // 获取用户对通知的设置 // 通过settings.authorizationStatus 来处理用户没有打开通知授权的情况 [UNUserNotificationCenter.currentNotificationCenter getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) { NSLog(@"%@",settings); }]; }// 在前台时收到通知 - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionBadge); }// 点击通知，从后台进入前台 - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler { NSString *identifier =response.actionIdentifier; if ([identifier isEqualToString:@"open"]) { NSLog(@"打开操作"); } else if ([identifier isEqualToString:@"close"]) { NSLog(@"关闭操作"); } completionHandler(); }

3、添加通知、包含一些操作

- (void)addNotification { // 创建一个通知内容 UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init]; content.badge = @1; content.title = @"title"; content.subtitle = @"subtitle"; content.body = @"body"; content.sound = [UNNotificationSound defaultSound]; content.categoryIdentifier = @"category"; // 通知触发器 UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:false]; // 通知请求 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:@"打开" options:UNNotificationActionOptionForeground]; UNNotificationAction *closeAction = [UNNotificationAction actionWithIdentifier:@"close" title:@"关闭" options:UNNotificationActionOptionDestructive]; UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"category" actions:@[openAction, closeAction] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction]; NSSet *sets = [NSSet setWithObject:category]; [UNUserNotificationCenter.currentNotificationCenter setNotificationCategories:sets]; }

- (void)removeNotifiation { // 移除待处理的通知 [UNUserNotificationCenter.currentNotificationCenter removePendingNotificationRequestsWithIdentifiers:@[@"noti"]]; // 移除已经处理的通知 [UNUserNotificationCenter.currentNotificationCenter removeDeliveredNotificationsWithIdentifiers:@[@"noti"]]; // 移除所有的通知 [UNUserNotificationCenter.currentNotificationCenter removeAllDeliveredNotifications]; [UNUserNotificationCenter.currentNotificationCenter removeAllPendingNotificationRequests]; }
