当我在iOS 5.1模拟器上运行我的项目时,它会显示出来
yld: lazy symbol binding failed: Symbol not found: _objc_setProperty_nonatomic_copy
Referenced from: /Users/apple/Library/Application Support/iPhone Simulator/5.1/Applications/3A003E5F-2C66-494F-BCC1-C3EE82F01464/dogTree.app/dogTree
Expected in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/Frameworks/Foundation.framework/Foundation
我没有5.1 SDK.但为什么库搜索路径是5.1而不是6.0？
我的所有项目都在iOS 6.0设备上运行,但是当我在iOS 5.0或5.1设备上安装时,它崩溃并显示如下消息.
请给我一些帮助,iOS 5.1 SDK是否有必要运行iPhone 5.1模拟器？
