iOS 本地通知提醒

一. iOS10以前
使用 UILocalNotification

- (IBAction)changed:(id)sender
{
    UISwitch* sw = (UISwitch*) sender;
    if (sw.on)
    {
        
        //在iOS8以后，不论是本地通知还是远程通知，在使用之前都需要对UILocalNotification的类型进行声明，否则不能使用
        UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
        UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
        
        
        
        // 创建一个本地通知
        UILocalNotification *notification = [[UILocalNotification alloc]init];
        // 设置通知的触发时间
        notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:0];;
        // 设置通知的时区
        notification.timeZone = [NSTimeZone defaultTimeZone];
        // 设置通知的重复发送的事件间隔
        notification.repeatInterval = kCFCalendarUnitMinute;
        // 设置通知的声音
        notification.soundName = @"gu.mp3";
        // 设置当设备处于锁屏状态时，显示通知的警告框下方的title
        notification.alertAction = @"打开";
        // 设置通知是否可显示Action
        notification.hasAction = YES;
        // 设置通过通知加载应用时显示的图片
        notification.alertLaunchImage = @"logo.png";
        // 设置通知内容
        notification.alertBody = @"轮到你下棋了，赶快走棋!";
        // 设置显示在应用程序上红色徽标中的数字
        notification.applicationIconBadgeNumber = 1;
        // 设置userinfo，用于携带额外的附加信息。
        NSDictionary *info = @{@"fkjava.org": @"key"};
        notification.userInfo = info;
        // 调度通知
        [app scheduleLocalNotification:notification];  // ①
    }
    else
    {
        // 获取所有处于调度中本地通知数组
        NSArray *localArray = [app scheduledLocalNotifications];
        if (localArray)
        {
            for (UILocalNotification *noti in localArray)
            {
                NSDictionary *dict = noti.userInfo;
                if (dict)
                {
                    // 如果找到要取消的通知
                    NSString *inKey = [dict objectForKey:@"key"];
                    if ([inKey isEqualToString:@"fkjava.org"])
                    {
                        // 取消调度该通知
                        [app cancelLocalNotification:noti];  // ②
                    }
                }
            }
        }
    }
}

// 只有当应用在前台时，该方法才会被调用
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{
    // 如果应用程序在前台，将应用程序图标上红色徽标中数字设为0
    application.applicationIconBadgeNumber = 0;
    // 使用UIAlertView显示本地通知的信息
    [[[UIAlertView alloc] initWithTitle:@"收到通知"
        message:notification.alertBody
        delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil] show];
}

二.iOS10

//MARK:本地通知
- (void)locoNotificationBtn {
    // 申请通知权限
    [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        
        // A Boolean value indicating whether authorization was granted. The value of this parameter is YES when authorization for the requested options was granted. The value is NO when authorization for one or more of the options is denied.
        if (granted) {
            
            // 1、创建通知内容，注：这里得用可变类型的UNMutableNotificationContent，否则内容的属性是只读的
            UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
            content.title = @"标题";
            content.subtitle = @"子标题";
            content.body = @"消息内容内容内容内容内容内容内容";
             // app显示通知数量的角标
            content.badge = @(1);
            // 通知的提示声音，这里用的默认的声音
//            content.sound = [UNNotificationSound defaultSound];
            //自定义声音
            content.sound = [UNNotificationSound soundNamed:@"6414.mp3"];
            
            NSURL *imageUrl = [[NSBundle mainBundle] URLForResource:@"xintianjiayinhang" withExtension:@"png"];
            UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:@"imageIndetifier" URL:imageUrl options:nil error:nil];
            // 附件 可以是音频、图片、视频 这里是一张图片
            content.attachments = @[attachment];
            //通知下拉放大
            //content.launchImageName = @"xintianjiayinhang";
            // 标识符
            content.categoryIdentifier = @"categoryIndentifier";
            
// 2、创建通知触发
            /* 触发器分三种：
             UNTimeIntervalNotificationTrigger : 在一定时间后触发，如果设置重复的话，timeInterval不能小于60
             UNCalendarNotificationTrigger : 在某天某时触发，可重复
             UNLocationNotificationTrigger : 进入或离开某个地理区域时触发
             */
            UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:2 repeats:NO];
// 3、创建通知请求
            UNNotificationRequest *notificationRequest = [UNNotificationRequest requestWithIdentifier:@"KFGroupNotification" content:content trigger:trigger];
            
// 4、将请求加入通知中心
            [[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:notificationRequest withCompletionHandler:^(NSError * _Nullable error) {
                if (error == nil) {
                    NSLog(@"已成功加推送%@",notificationRequest.identifier);
                }
            }];
        }else{
            NSLog(@"用户点击不允许");
        }
        
    }];
  }
