前言  
推送对App的重要性不言而喻，APP里的某些内容是需要用户开启推送权限才能给用户精准展示，才能及时通知用户。

下面我们通过一个demo实现对推送的监听，以及弹窗的效果，希望能帮助到大家。

效果图如下：

一、在AppDelegate里添加以下代码可以使APP弹窗通知权限框

#pragma mark ==========请求用户给权限==========
    - (void)registerPushNotificationAuthorization:(UIApplication *)application{
        if (@available(iOS 10.0, *)) {
            //iOS 10 later
            UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
            //必须写代理，不然无法监听通知的接收与点击事件
            center.delegate = self;
            [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
                if (!error && granted) {
                    //用户点击允许
                    NSLog(@"注册成功");
                }else{
                    //用户点击不允许
                    NSLog(@"注册失败");
                }
            }];
            // 可以通过 getNotificationSettingsWithCompletionHandler 获取权限设置
            //之前注册推送服务，用户点击了同意还是不同意，以及用户之后又做了怎样的更改我们都无从得知，现在 apple 开放了这个 API，我们可以直接获取到用户的设定信息了。注意UNNotificationSettings是只读对象哦，不能直接修改！
            [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
                NSLog(@"========%@",settings);
            }];
        }else if (@available(iOS 8.0, *)){
            //iOS 8 - iOS 10系统
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
            [application registerUserNotificationSettings:settings];
        }else{
            //iOS 8.0系统以下
            [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
        }
        //注册远端消息通知获取device token
        [application registerForRemoteNotifications];
    
    }

二、判断用户是否同意了推送权限

#pragma mark ==========YES有权限  NO无权限==========
    -(void)seeCurrentNotificationStatus{
        if (@available(iOS 10 , *)){
            WEAKSELF;
             [[UNUserNotificationCenter currentNotificationCenter] getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
                 STRONGSELF;
                if (settings.authorizationStatus == UNAuthorizationStatusDenied){
                    // 没权限
                    NSLog(@"无推送权限，弹窗处理");
                    [strongSelf pushNotifcationView];
                }
            }];
        }else if (@available(iOS 8 , *)){
            UIUserNotificationSettings * setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
            if (setting.types == UIUserNotificationTypeNone) {
                // 没权限
                NSLog(@"无推送权限，弹窗处理");
                [self pushNotifcationView];
            }
        }else{
            UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
            if (type == UIUserNotificationTypeNone){
                // 没权限
                NSLog(@"无推送权限，弹窗处理");
                [self pushNotifcationView];
            }
        }
    }

三、推送权限弹窗逻辑

#pragma mark ==========弹窗出推送权限==========
    -(void)pushNotifcationView{
        //一天之内只提示一次
        NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];
        //拿到当前时间
        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"yyyy-MM-dd"];
        //当前时间
        NSDate *nowDate = [NSDate date];
        NSString *nowDateStr= [dateFormatter stringFromDate:nowDate];
        //之前时间
        NSString *agoDateStr = [userDefault objectForKey:@"saveNowDate"];
        //判断时间差
        if ([agoDateStr isEqualToString:nowDateStr]) {
            //是当天时间
        }else{
            //弹窗
            //主线程使用
            dispatch_async(dispatch_get_main_queue(), ^{
                [[HBOpenPushNoticeView new] show];
            });
            //保存当前时间
            [userDefault setObject:nowDateStr forKey:@"saveNowDate"];
            [userDefault synchronize];
        }
    
    }
