iOS10添加本地通知

UILocalNotification 已经在 iOS10 中被废弃了。需要使用 UserNotifications.Framework 来推送通知。

获取权限

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    // 使用 UNUserNotificationCenter 来管理消息
    UNUserNotificationCenter *unCenter = [UNUserNotificationCenter currentNotificationCenter];
    // 注册回调代理
    unCenter.delegate = self;
    // 获取授权，第一次调用会弹出授权对话框
    [unCenter requestAuthorizationWithOptions:UNAuthorizationOptionSound|UNAuthorizationOptionAlert|UNAuthorizationOptionBadge completionHandler:^(BOOL granted, NSError * _Nullable error) {
        // granted 是否获取用户授权
    }];
}

#pragma mark - UNUserNotificationCenterDelegate
// 收到通知时的回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
    // 处理完通知后调用，通知系统已处理完毕
    completionHandler();
}

注册本地通知

// 注册通知
+ (void)registerLocalNotification {
    UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
    
    // 通知内容，Mutable表示内容可变化
    UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
    content.title = @"通知标题";
    content.body = @"通知内容";
    content.sound = UNNotificationSound.defaultSound; // 通知声音
    // 自定义通知提示音
    content.sound = [UNNotificationSound soundNamed:@"sound.wav"];
    content.badge = @1; // 角标数字
    
    // 触发器，10s 后推送本地通知
    UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];
    
    // 注册本地通知
    NSString *identifier = @"notification_id"; // 通知的id
    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier content:content trigger:trigger];
    [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
        NSLog(@"registerLocalPush error: %@", error);
    }];
}

// 根据 identifier 取消指定的通知
+ (void)removeLocalNotification:(NSString*)identifier {
    UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
    [center removePendingNotificationRequestsWithIdentifiers:@[identifier]];
}

// 取消所有的通知
+ (void)removeAllLocalNotifications {
    UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
    [center removeAllDeliveredNotifications];
    [center removeAllPendingNotificationRequests];
}
