我拿到这些果马-OLinker的错误,我不知道如何阅读这些事情。 我在项目进口“CLCredential Header.h”和“CLCredential Header.m”之后就发现这些错误。
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_SFHFKeychainUtils", referenced from:
objc-class-ref in CLCredentialHandler.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
确保在“电源”中为你的建筑目标建设阶段。 有时,在Xcode中增加一个项目的档案,并没有在适当目标中增加所有执行档案。
有时,我从另一个项目中抽出一个班子,忘记在播的窗口中标上“达到目标”。 我认为这是一个非常合理的问题。 错误信息也不是非常直观的。 这种办法在XCode易于点击该项目,并点击“Build Phases”,然后打开“Compile Source”称“+”。 这里有些情况更说所有话。
因此,如果错误看起来如此,它就告诉我数据Access类别没有界定。
我承认,这是我刚刚被拖走的一类,并投到了该项目中。 我在我的项目中增加数据。
最初,我本可以通过标明“对目标的补充”加以避免。
If above answers does not work for you then check you have added Security framework. If not then add it in Build Phase section of Targets. Should be fine then :)
