上次打包还正常的，这次一打包居然出现这一堆总是来，郁闷。原本还准备打几个包测试没问题就发布个版本的，看来又得被耽搁了。报出的几个错误如下：

正在查找原因。。。
排查：
通过在代码中搜索"__ISN_ResolveConflictingSavedGames",等，发现在是IOSNative这个插件里的代码，由此再一回想，肯定是IOSNativeSettings中之前做过的修改有关系，那时没事把Game Center和Social Sharing的勾给去了。
经再次打包测试，真是的以上的问题，OK 解决问题了。
真是没事找抽型的，呼！！！
总结
还有一个很值得注意的就是寻找答案的方法，在遇到这个问题时，前思后想都觉得没道具，怎么好好的，也没改哪里却突然遇到这种问题，一下子无从下手，搜遍百度也没有找到一样的答案，这时应该在报错的提示中仔细阅读，如__ISN_DeleteSavedGame 这个关键词，还有后面in Bulk_Assembly-CSharp_0.o 这段提示，表示在CSharp中，所以这个问题就可以到CSharp中搜索上面的那个关键词，一查找，再看一下cs文件的路径，就全然明白了，也马上想起了之前做过的哪些改动。

游戏中加载时无法读取数据库：InvalidOperationException: No connection associated with this command

在Unity编辑器中倒还是一切正常，但是Xcode中打包成功安装后，真机上却在加载进度条卡住了，具体内容如下，可以大体看出是数据库表加载的问题。

InvalidOperationException: No connection associated with this command

问题的原因已找到：是因为在登陆界面引用了baseTable只读数据库的问题，去除读取这类数据库，改用其它方式实现功能，如此解决问题。至于为什么会读取这类数据库表会出错，可能是还没生成出数据库表就开始要读取了的原故吧。

Apple Mach-O Linker (Id) Error Linker command failed with exit code 1

在新MAC上打包出现问题如下：
Apple Mach-O Linker (Id) Error

Linker command failed with exit code 1

解决方法：

进入项目TARGETS/选择您的项目

General/Deployment Info/Deployment Target 在此选择了8.0版本

可能是使用的Xcode8.x的原因，5.1.1版本无法正常打包，显示最低版本为基础8.0

Unity4.69破解详细步骤

Error loading page
SSL peer certificate or SSH remote key was not OK
Unity
前两天打开照常打开Unity时，再一次遇到这个问题，又是束手无策，安装破解、断网等都无法解决，郁闷！

以下是解决的详细步骤，我使用的是Unity4.6.9版本。
1. 断网并打开Unity4.69，出现如下界面，选择Manual Activation按钮
unity_02
2. 进入如下界面，并点击Save License按钮保存文件。
unity_03
3. 保存好文件后，再联网进入https://license.unity3d.com/manual 如下图，并上传刚下载的Unity_v4.6.9f1.alf文件。
unity_04
4. 如下图Next进入下一步
unity_05
5. 如下图，下载文件。
unity_06

到此完成安装，正常进入选择工程项目界面

7.到此完成了无法登陆Unity的启动问题，但看惯了深灰色的界面，就得破解Pro版本，接下来的步骤：使用破解软件获得Unity_v4.x.ulf文件，然后断网重复第2步图中的Load License按钮，载入生成的破解文件，启动Unity软件，熟悉的深灰色界面映入眼前，OK！

error CS0246: The type or namespace name `LocalNotification’ could not be found.

从Unity4.6顺利升级到5.3+，除了新手指示每次都出现和出现作弊提示以外，目前来看一切能正常，但在打包时出现如下报错

Assets/Scripts/Game/GameStarter/Notification.cs(94,9): error CS0246: The type or namespace name `LocalNotification' could not be found. Are you missing a using directive or an assembly reference?

1 2	Assets/Scripts/Game/GameStarter/Notification.cs(94,9): error CS0246: The type or namespace name `LocalNotification' could not be found. Are you missing a using directive or an assembly reference?

问题原因：
去除!UNITY_EDITOR模式，可以看到unity中会提示语法过时

Assets/Scripts/Game/GameStarter/Notification.cs(27,13): error CS0619: `UnityEngine.LocalNotification' is obsolete: `LocalNotification is deprecated. Please use iOS.LocalNotification instead (UnityUpgradable) -&gt; UnityEngine.iOS.LocalNotification'

1 2	Assets/Scripts/Game/GameStarter/Notification.cs(27,13): error CS0619: `UnityEngine.LocalNotification' is obsolete: `LocalNotification is deprecated. Please use iOS.LocalNotification instead (UnityUpgradable) -> UnityEngine.iOS.LocalNotification'

解决办法：在LocalNotification前面添加UnityEngine.iOS.解决问题。

UnityEngine.iOS.LocalNotification localNotification = new UnityEngine.iOS.LocalNotification();
            localNotification.fireDate = newDate;
            localNotification.alertBody = message;
            localNotification.applicationIconBadgeNumber = 1;
            localNotification.hasAction = true;

UnityEngine.iOS.LocalNotification localNotification = new UnityEngine.iOS.LocalNotification();

localNotification.fireDate = newDate;

localNotification.alertBody = message;

localNotification.applicationIconBadgeNumber = 1;

localNotification.hasAction = true;

处理后顺利打包导出XCode项目。

苹果开发者内购测试遇到的一个大坑

已经上线一款是能够正常通过内购的，修改并添加一些小功能，在另一个帐号中上线。由于是新的一个帐户，其它都一切正常，就是内购时无法连接，一直是转圈后就消失了，折腾了好几天，今天又经过几轮测试后，证明是苹果帐号的问题，不是APP内的问题了。折腾了好几天，今天才突然想到，内购除了在应用内添加内购类目以外，还需在银行、协议里面填写相关资料才能正常进入测试以及使用。

https网站中终于可以解析php文件了

搁置了几天时间，今天闲来把502的问题解决一下，在amh界面中重新创建一个空间，然后ssl也配置上，然后把阿里云盾打包下载的pem文件用记事本打开，复制、粘贴进SSL配置文件里（如下图）

ssl

在# vi /usr/local/nginx/conf/vhost/game.adongblog.com.conf(这里是你在amh界面中配置出来空间后自动创建的)，把这里调整一下：

#------SSL BEGIN
listen 443;
ssl on;
ssl_certificate /usr/local/nginx/conf/ssl/game.adongblog.com.pem; 
#AMH界面创建好后，上面这一行他指定的是.crt的文件，把他修改过来。
ssl_certificate_key /usr/local/nginx/conf/ssl/game.adongblog.com.key;
#上面这一行他默认指定的是pem的文件，在阿里云盾创建的证书打包下载的key为这个，把他修改为.key的后缀。
#------SSL END

#------SSL BEGIN

listen 443;

ssl on;

ssl_certificate /usr/local/nginx/conf/ssl/game.adongblog.com.pem;

#AMH界面创建好后，上面这一行他指定的是.crt的文件，把他修改过来。

ssl_certificate_key /usr/local/nginx/conf/ssl/game.adongblog.com.key;

#上面这一行他默认指定的是pem的文件，在阿里云盾创建的证书打包下载的key为这个，把他修改为.key的后缀。

#------SSL END

最后上传一个<?php phpinfo(); ?>文件测试，可以正常打开了。。。

nginx中无法解析php文件的问题

高兴的太早，可以正常访问还是http下的，而在https下还是不能正常解析php文件，还是显示 502 Bad Gateway
