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 ...
