我刚刚将我所有的 CocoaAsyncSocket 代码标记为非 ARC 代码,它给了我以下 3 个错误:
Undefined symbols for architecture armv7:
"_kCFStreamNetworkServiceTypeVoIP", referenced from:
-[GCDAsyncSocket enableBackgroundingOnSocketWithCaveat:] in GCDAsyncSocket.o
"_kCFStreamNetworkServiceType", referenced from:
-[GCDAsyncSocket enableBackgroundingOnSocketWithCaveat:] in GCDAsyncSocket.o
"_kCFStreamPropertySSLSettings", referenced from:
-[GCDAsyncSocket maybeStartTLS] in GCDAsyncSocket.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
有谁知道这意味着什么以及如何解决它?
