这是什么原因dyld`dyld_fatal_error，在iOS上不兼容的api？ [英] Which is the cause for dyld`dyld_fatal_error, a incompatible api on iOS?

问题描述

我把我的项目的一部分移到iOS 5 / ARC。最旧的项目之一（iOS 4.2，armv6支持iPod Touch 2g）给我：

I'm moving part of my projects to iOS 5 / ARC. One of the oldest project (iOS 4.2, armv6 for support iPod Touch 2g) is giving to me:

dyld`dyld_fatal_error:
0x8feb1070:  int3   
0x8feb1071:  nop    

到主。必须是一些lib /代码更新到iOS 5，但是哪一个？可以使用比猜测更好的方法

Just after the launch image but before going to main. Must be some lib/code updated to iOS 5, but which one? Is possible to use a better method than guess??

推荐答案

自己尝试重现使用Xcode4.3.2和iOS5.1的iOS5.1这个项目。问题是，Xcode4.3.2上的标准项目模板配置为iOS5，它具有早期iOS版本不支持的一些功能。在我的情况下，GLKit框架被拉入，并不支持我的iPhone3G运行iOS4.2。我得到的错误就像你的错误：

Ran to this problem myself trying to reproduce this project using Xcode4.3.2 with SDK iOS5.1. The issue was that the standard project template on Xcode4.3.2 configures for iOS5, which has some features that earlier iOS versions don't support. In my case, the GLKit Framework was being pulled in and was not supported on my iPhone3G running iOS4.2. The error I was getting was just like yours:

dyld`dyld_fatal_error:
0x2fe01080:  trap   
0x2fe01084:  mov    r0, r0

仔细查看控制台输出，您可以看到什么是导致应用崩溃：

Upon closer review of the Console Output you can see what's causing the app to crash:

dyld: Library not loaded: /System/Library/Frameworks/GLKit.framework/GLKit
Referenced from: /var/mobile/Applications/A60A53B1-F87D-467D-BB0B-82C603049202/HiJackInTheBox.app/HiJackInTheBox
  Reason: image not found
(lldb) 

错误意味着在安装应用程序的目标上的iOS驻留中找不到GLKit框架。框架被拉入到Project-> BuildPhases-> LinkBinaryWithLibraries下的构建中。

The error meant that the GLKit framework was not found in the iOS resident on the target where the app was installed. The framework was being pulled into the build under Project->BuildPhases->LinkBinaryWithLibraries.

因此，为了纠正这个问题，我需要删除GLKit框架和所有代码引用它。然后构建成功并在目标设备上运行。希望这有助于！

So to correct the problem I needed to remove the GLKit framework and all code making references to it. Then the build succeeded and ran on the target device. Hope this helps!
