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:
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).
