痛定思痛之下，还是决定写篇文章，长期更新每次打包遇到的问题，以及解决问题的方案。

Android比IOS头痛很多，自从升级了Gradle打包模式之后，事件就越来越多，促使我写这篇文章的最后一点刺激来自于升级了Unity2019，加入了Google Admob，要求Ndk 16b版本，也对Android SDK版本有一些要求，Ios从打包测试（整1天）完成之后，打包Android后报错了。

其实之前也遇到打包问题，Ios都还比较好说，比如上次加入了一个广告联盟平台，Android打包就报方法超65535的一个错，需要引用Gradle，在广告技术对接群的支持下花了大概几天的时间才OK。

Unity打包出错通常会报明原因，但是Android和Ios的区别是，Android告诉你去参见这个网址， Ios告诉你怎么怎么做。通常情况下，你不得不把报错去Google一下。

IOS篇

Unity里 Build，打开Xcode，插入设备，不做任何修改直接运行不报任何错则是我们的目标，正式上线的项目貌似

ios对打包的支持已经很不错了，更新Xcode，下载Unity的IOS编译环境，为了提升效率，以下步骤与插件不可或缺

在Unity Player Setting里面设置好你的 Apple Team ID
CocosPods 插件安装，没有3方SDK不需要，有的话还是加上吧，特别方便

Apple Team ID在这里发现 https://developer.apple.com/account/#/membership/XXXXX ，登录你的开发主帐号XXXX即为ID，也可以在Membership选项卡里发现，如图所示

从Unity5.x 到2019，打包Xcode的工程在2分钟内，从Xcode到真机上3分钟，当然和项目内容（主要是SDK）与电脑性能了，我测试时是MacBookPro15寸2014 + 中小型项目（集成IAP和GoogleAdmob）。

遇到cocoapods 相关的错误，，请检查你的IOS版本等级，调用9.0以上就OK。2019年10月19号更新，需要安装cocoaPods app在Mac上。

Android 篇

原因，加入了Admob，应该是这里出的原因：

这尼玛，凭我第6感的灵性，我并没有去找哪哪哪网址，我修改了以下设置：

Android以下的4个，全部勾了，自己选位置，打包，洗澡回来，Done！(Mac端 Unity2019.2.2f1)

在Windows上，Unity2019 2.3f1尼玛死活打包不成功，无奈下载了自带的Android Support支持，xx的

还是报错，今日元气大伤，让我结束这痛苦的一天，改日再约。
