ios 10 新的notification UserNotif

本篇文章不多写别的没有用的，因为在新闻和各大博客里面都有了，这里我就直接放上代码了
详细介绍可以看猫爷的文章

1.注册通知方式更改

使用Usernotification之前 我们先需要引入frameworkUserNotifications.framework

#import <UserNotifications/UserNotifications.h>
//引入头文件 设置好delegate
@interface AppDelegate ()<UNUserNotificationCenterDelegate>

- (void)unUserNotificationSettting{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (error == nil) {
            NSLog(@"注册通知成功");
        }else{
            NSLog(@"注册通知失败 error is %@",error);
        }
    }];
    
    [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
        NSLog(@"unnotification setting is %@",settings);
    }];
}

2.发送通知

- (void)sendUNUserNotification{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  //这里要用mutable content  要不然内容添加不进去 和dictionary原理一样
    UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc]init];
    content.title = @"titile";
    content.subtitle = @"subTitle";
    content.body = @"This is body";
    content.sound = [UNNotificationSound defaultSound];
    content.userInfo = @{@"url":@"https:www.baidu.com"};
//新的通知可以加入图片，视频，声音等资源  方式是在content中加入attchments
    NSError *err = nil;
//url 指的就是资源的URL 只可以是本地的 但是可以通过先下载到本地然后再使用  
//本地图片
    NSString *localImageString = [[NSBundle mainBundle]pathForResource:@"image" ofType:@"gif"];
    NSURL *url = [NSURL fileURLWithPath:localImageString];
//但是注意 不在bundle中的文件 通知发送出去后会自动删除这个文件，也就是说下载好的文件附在通知中  发送出去就没有了
    UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:@"notificaitonIden" URL:url options:nil error:&err];
    content.attachments = @[attachment];
//新的通知可以替换前一条通知  方式就在于相同的request iden  不同的iden 就是多条通知
//可以延迟发送  创建以个trigger 这里没有延迟 trigger 就写成nil
    //UNNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];
    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier: [NSString stringWithFormat:@"usernotification%@",poi.name] content:content trigger:nil];

//添加到发送队列中
    [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
        if (error == nil) {
            NSLog(@"发送本地通知成功");
        }else{
            NSLog(@"发送本地通知失败 error is %@",error);
        }
    }];

3.响应通知 注意 不在原来的didreceive delegate中

#pragma mark -  UNUserNotificationCenterDelegate
//弹出通知之前  可以进行修改notification中的内容
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
    NSString *identifier = notification.request.identifier;
    UNNotificationPresentationOptions options = UNNotificationPresentationOptionNone; //默认什么也不做，不显示
    //项目中出现过的通知都设置为前台可以显示
    // options = UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert;
    if (identifier == nil) {
        completionHandler(options);
        return;
    }
    //设置完成之后必须调用这个回调，
    completionHandler(options);
}
//通知响应
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
    NSDictionary *dic = response.notification.request.content.userInfo;
    completionHandler();
}
