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.

id vs NSObject

There's often confusion about the difference between the following three declarations in Objective-C: id foo1; ->   It simply declares a pointer to some Objective-C object,  If you don't want (or can't have) any type checking, then use   id . if you do want compile-time type checking, you must decide between the second and third cases.. NSObject *foo2; ->  declaring a generic pointer of type NSObject* id<NSObject> foo3; ->   pointer to  any  object that behaves like an NSObjec , "foo3 is a pointer to an object of any type that behaves like an NSObject" , ( you really don't care what class the object is, you only care that it  behaves  like an NSObject.) The first one is the most common. It simply declares a pointer to some Objective-C object (see  /usr/include/objc/objc.h ).  id  gives the compiler no information about the actual type of the object, so the compiler cannot do compile-time type ...
