unity项目IOS本地推送消息

　　unity项目ios客户端实现本地消息推送，需求游戏在后台运行的时候，推送奖励已满。

　　实现。

　　1.注册通知：

　　　　在application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions中调用注册通知函数registerAPN

- (void)RegisterAPN {
    // 注册通知
    if (@available(iOS 10.0, *)) { // iOS10 以上
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
            if (!error) {
                NSLog(@"推送注册成功");
            }
        }];
    } else {// iOS8.0 以上
        UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    }
}

　　2.检查权限

检查app是否开启通知权限

- (void)CheckUserNotificationEnable{ // 判断用户是否允许接收通知
    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
            if (settings.notificationCenterSetting == UNNotificationSettingEnabled) {
                NSLog(@"打开了通知");
                if ([PlatformSDKManager Instance].sdkHandler.CustomEvent)
                {
                    [PlatformSDKManager Instance].sdkHandler.CustomEvent("Callback_CheckNotifyEnable:true");
                }
            }else {
                NSLog(@"关闭了通知");
                dispatch_sync(dispatch_get_main_queue(), ^{
                    //刷新UI的代码放到主线程执行
                    [self ShowAlertView];
                });
            }
        }];
    }else {
        if ([[UIApplication sharedApplication] currentUserNotificationSettings].types == UIUserNotificationTypeNone){
            NSLog(@"关闭了通知");
            dispatch_sync(dispatch_get_main_queue(), ^{
                [self ShowAlertView];
            });
        }else {
            NSLog(@"打开了通知");
        }
    }
}

　　

　　3.添加通知

在需要使用的地方调用这个函数，奖励满足时候，通过lua调用这个函数

- (void)AddLocalNoticeWithID:(NSString *)noticeId Title:(NSString*)title Context:(NSString*)context Time:(int)time{
    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
        // 标题
        content.title = title;
        //content.subtitle = [dataDict objectForKey:@"context"];
        // 内容
        content.body = context;
        // 声音
        content.sound = [UNNotificationSound defaultSound];
        content.badge = @1;

        int secTime = time;
        
        if(secTime <= 0)
        {
            return;
        }
        NSString *identifier = noticeId;
        NSTimeInterval time = [[NSDate dateWithTimeIntervalSinceNow:secTime] timeIntervalSinceNow];

        UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:time repeats:NO];
        
        UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier content:content trigger:trigger];
        
        [center addNotificationRequest:request withCompletionHandler:^(NSError *_Nullable error) {
            NSLog(@"成功添加推送");
        }];
    }

　　4.移除通知

// 移除某一个指定的通知
- (void)RemoveOneNotificationWithID:(NSString *)noticeId {
    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        [center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
            for (UNNotificationRequest *req in requests){
                NSLog(@"存在的ID:%@\n",req.identifier);
            }
            NSLog(@"移除currentID:%@",noticeId);
        }];
        
        [center removePendingNotificationRequestsWithIdentifiers:@[noticeId]];
    }else {
        NSArray *array=[[UIApplication sharedApplication] scheduledLocalNotifications];
        for (UILocalNotification *localNotification in array){
            NSDictionary *userInfo = localNotification.userInfo;
            NSString *obj = [userInfo objectForKey:@"noticeId"];
            if ([obj isEqualToString:noticeId]) {
                [[UIApplication sharedApplication] cancelLocalNotification:localNotification];
            }
        }
    }
}

// 移除所有通知
- (void)RemoveAllNotification {
    if (@available(iOS 10.0, *)) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        [center removeAllPendingNotificationRequests];
    }else {
        [[UIApplication sharedApplication] cancelAllLocalNotifications];
    }
}

　　5.跳转到设置界面

// 如果用户关闭了接收通知功能，该方法可以跳转到APP设置页面进行修改
- (void)GoToAppSystemSetting {
    dispatch_async(dispatch_get_main_queue(), ^{
        UIApplication *application = [UIApplication sharedApplication];
        NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
        if ([application canOpenURL:url]) {
            if (@available(iOS 10.0, *)) {
                if ([application respondsToSelector:@selector(openURL:options:completionHandler:)]) {
                    [application openURL:url options:@{} completionHandler:nil];
                }
            }else {
                [application openURL:url];
            }
        }
    });
}

　　

其中在customAppcontroller（定制UnityAppcontroller）实现<UNUserNotificationCenterDelegate>代理，并且实现下面两个方法

#pragma mark - iOS10-UNUserNotificationCenterDelegate
// 弹出通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
//当游戏处于前台时候，本地推送的设置 ，此处可设置不显示本地推送
    completionHandler(UNNotificationPresentationOptionSound);
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
//当点击本地推送横栏时，进行的操作，这里是把角标红点进行置空
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}

　　

差不多就是这些
