使用 Xcode 7、Unity 5.2.3f1、iOS 9.1 基础 SDK 构建时出错

Errors when building with Xcode 7, Unity 5.2.3f1, iOS 9.1 base SDK

提问by user1615898

I'm trying to build a sample Unity app with Xcode 7, Unity 5.2.3f1, iOS 9.1 base SDK, but get these compile errors when trying to run the app in Xcode. I already set scripting backend = IL2CPP, Architecture = Universal, but it did not help.

我正在尝试使用 Xcode 7、Unity 5.2.3f1、iOS 9.1 基础 SDK 构建示例 Unity 应用程序，但在尝试在 Xcode 中运行该应用程序时出现这些编译错误。我已经设置脚本后端 = IL2CPP，架构 = 通用，但它没有帮助。

I solved this issue by checking "Symlink Unity Library" in Build Settings and made sure the build is for device, not simulator.

我通过检查构建设置中的“Symlink Unity Library”解决了这个问题，并确保构建是针对设备的，而不是模拟器。

I had this error because my iOS device changed from an iphone 5 to a generic iOs device I assume because the cord wasn't high quality and it lost connection.

我遇到此错误是因为我的 iOS 设备从 iphone 5 更改为通用 iOs 设备，我认为是因为电源线质量不高，而且连接丢失。

If XCode loses connection it tries to build for a generic device.

如果 XCode 失去连接，它会尝试为通用设备构建。

I just reconnected the phone and rebuilt fixed my issue.

我刚刚重新连接手机并重建修复了我的问题。

In order to get rid of this errors and run the game on the simulator:

为了摆脱这个错误并在模拟器上运行游戏：

In Unity go to Edit > Project Settings > Playerit will open Player Settings in the inspector. Then select the IOS platform and Other Settings >Target SDK > Simulator SDK.

在 Unity 中，转到“编辑”>“项目设置”>“播放器”，它将在检查器中打开“播放器设置”。然后选择IOS平台和Other Settings >Target SDK > Simulator SDK。

This solved the 200 linking errors saying "Undefined symbols for architecture x86_64" and it works on the simulator.

这解决了 200 个链接错误，提示“架构 x86_64 的未定义符号”，并且它可以在模拟器上运行。

with Unity 5.4.03f I was getting unity xcode undefined symbols for architecture arm64

使用 Unity 5.4.03f 我得到了架构 arm64 的统一 xcode 未定义符号

To solve it, I have downgraded my unity to 5.3.5f1 personal . With player settings Scripting backend:IL2CPP and Architecture:Universal with xcode 7.3.1.

为了解决这个问题，我将我的 unity 降级为 5.3.5f1 personal 。使用播放器设置 Scripting backend:IL2CPP 和 Architecture:Universal with xcode 7.3.1。

You can check size of libiPhone-lib.a to identify the difference of compiling with both unity versions.

您可以检查 libiPhone-lib.a 的大小以识别使用两个统一版本编译的差异。
