以项目中集成第三方开源库为例，经常需要修改Other Linker Flags选项，默认xcode8.1没有这个选项（或者没有找到），此时：
找到项目文件 ：＊.xcodeproj ，右键显示包内容，用文本编辑器打开：project.pbxproj
定位到：
/* Begin XCBuildConfiguration section */
下面一般有两个配置: Debug 和 Release
加入如下内容：
OTHER_LDFLAGS = (
"-lctemplate-iOS",
"-letpan-ios",
"-lxml2",
"-lsasl2",
"-liconv",
"-ltidy",
"-lz",
"-lc++",
"-lresolv",
"-stdlib=libc++",
"-ObjC",
);
完整配置文件中相关内容如下：
