在Xcode 5.0中尝试构建我的游戏（使用Unity 4.5）时出现此错误。我试图删除＆＃34;图书馆/框架搜索路径＆＃34; （似乎是许多人的解决方案）但没有成功。
我正在使用＆＃34; Google Play游戏服务＆＃34;插件和＆＃34;社交移动插件＆＃34; （使用Facebook SDK for Unity）。
由于我没有很多Xcode的经验，所以我真的不知道我在这里处理什么，所以我很抱歉下面的长错误信息，但也许有人可以从中得到一些东西：
（我也试图找到这个＆＃34; liPhone库＆＃34;但我想我误解了一些东西，因为我无法在任何地方找到类似的东西。）
Apple Mach-O链接器错误：
ld: library not found for -liPhone-lib
clang: error: linker command failed with exit code 1 (use -v to see invocation)
错误附带的其余部分：
