embedded dylibs/frameworks are only supported on iOS 8.0 and later 错误解决

ld: warning: embedded dylibs/frameworks only run on iOS 8 or later
ld: embedded dylibs/frameworks are only supported on iOS 8.0 and later (@rpath/XXX.framework/XXX) for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方法：选择低版本号的开发环境。又一次编译XXX的framework
