What does -ObjC and -all_load mean?

The -ObjC Linker Flag (https://developer.apple.com/library/mac/qa/qa1490/_index.html) Passing the  -ObjC  option to the linker causes it to load  all  members of static libraries that implement any Objective-C class or category. -all_Load Linker Flag (http://stackoverflow.com/questions/2906147/what-does-the-all-load-linker-flag-do) -all_load forces the linker to load all object files from every archive it sees, even those without Objective-C code.
