带有弱链接的新框架在优胜美地上运行的iOS Simulator 7.1崩溃(未找到符号:_objc_isAuto) [英] iOS Simulator 7.1 crash running on Yosemite with weak linked new frameworks (Symbol not found: _objc_isAuto)

问题描述

我刚刚更新到xCode 6.1，不得不重新安装我的iOS 7模拟器.

I have just updated to xCode 6.1 and had to reinstall my iOS 7 simulators.

除了5s iOS 7.1 SIM卡之外，我还可以在所有模拟器上运行我的应用程序. 我遇到了崩溃

I can run my app on all the simulators apart from the 5s iOS 7.1 sim. I get this crash

dyld: Symbol not found: _objc_isAuto
  Referenced from: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
  Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/lib/libobjc.A.dylib
 in /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
(lldb) 

有什么作用?有什么想法为什么这个SIM卡会崩溃?

What gives? Any ideas why this sim crashes?

谢谢

推荐答案

如果您是针对iOS 8.x SDK构建项目的，并且无法轻松链接iOS 8.x的新框架，则可能会发生此问题.可以在OS X 10.10中使用，并且可以在iOS 7.1模拟器中运行.

This issue can occur if you are building your project against the iOS 8.x SDKs and are weak linking a framework that is new to iOS 8.x and also present in OS X 10.10 and you run in the iOS 7.1 simulator.

Xcode 6.1发行说明提到了此问题:

如果某个应用与iOS 8 SDK和OS X中的新框架之间存在弱链接 10.10 SDK，如果运行目标是较旧的iOS运行时的iOS模拟器且主机系统正在运行OS X，则它可能无法运行 优胜美地(17807439)

If an app is weak linked against frameworks new in iOS 8 SDK and OS X 10.10 SDK, it may fail to run if the run destination is an iOS Simulator for older iOS runtimes and the host system is running OS X Yosemite. (17807439)

此问题已在更新的iOS 7.1模拟器运行时中得到解决，该更新可以从Xcode 6.2 beta 4及更高版本下载(我认为beta3可能也起作用).

The issue is resolved in the updates iOS 7.1 simulator runtime that can be downloaded from Xcode 6.2 beta 4 an later (and I think possibly beta3 worked as well).
