? ? 在使用socket過程中出現(xiàn)了一些問題。最后終于解決了bug弟疆，在這里和大家分享一下。
使用SocketRocket 盗冷，下載下來庫文件進(jìn)行使用的時(shí)候怠苔，直接導(dǎo)入的庫，出現(xiàn)了一下問題仪糖。
Apple Mach-O Linker (ld) Error Group
1柑司、"_utf8_nextCharSafeBody", referenced from:
2、clang: error: linker command failed with exit code 1 (use -v to see invocation)
出現(xiàn)這些情況是因?yàn)橐眠@塊出了問題锅劝，
最后需要導(dǎo)入庫文件攒驰，
在項(xiàng)目targets中選擇build phases選項(xiàng)中l(wèi)ink binary with libaries 中添加 libicucore.tbd可解決這個(gè)錯(cuò)誤。
如使用的是cocopods導(dǎo)入的SocketRocket故爵。
則會(huì)出現(xiàn)三個(gè)警告玻粪。

1、SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
解決辦法：在前面加上（void）即如下所示：
(void)SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
替換掉就可以了
