访问@property表单ARC静态库时ARC App崩溃 [英] ARC App Crashes when accessing @property form ARC static lib

问题描述

我有一个ARC（自动引用计数）构建静态库（也是ARC）的应用程序。该应用程序将正常启动，但当执行一个读取或写入静态库中@property的操作时，应用程序将崩溃并显示以下错误：

I have a ARC (automatic-reference-counting) app that builds a static library (also ARC). The app will launch fine but when the an action is performed that reads or writes to a @property in the static library the app will crash with this error:

dyld: lazy symbol binding failed: Symbol not found: _objc_setProperty_nonatomic
  Referenced from: /var/mobile/Applications/0E7ADBB4-FFE5-4CEB-B418-8A35A92E99D4/MyApp.app/MyApp
  Expected in: /usr/lib/libobjc.A.dylib

所有建议都是关于将非ARC库链接到ARC应用程序（反之亦然）。但这些都是ARC。

All the advice has been about linking non-ARC libraries to ARC Apps (or vice-versa). But these are both ARC.

推荐答案

应用程序的基本SDK 已设置到iOS 6和 iOS部署目标设置为iOS 5.0但是对于静态库， Base SDK & iOS部署目标设置为iOS 6.

The app's Base SDK was set to iOS 6 and iOS Deployment Target was set to iOS 5.0 however for the static library both the Base SDK & iOS Deployment Target were set to iOS 6.

确保 Base SDK &应用程序和库中匹配的 iOS部署目标解决了这个问题。

Making sure the Base SDK & iOS Deployment Target matched in the app and library solved this problem.
