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)

原因：主要是因为XXX的framework支持的最低开发环境为8.0，而使用该framework的工程支持版本为8.0以下（我这里的环境为4.3）

解决方法：选择低版本的开发环境，重新编译XXX的framework
