You can also call another init method in the same class, but in the

before you start initializing your object

    - (id)initWithParam:(int)param

        if ( (self=[self init]) != nil )
            {
            // [self init] did basic initialization
            // do more initialization with param here
            iVar = param;

I guess you mean:

     - (id)initWithParam:(int)param
     {
         if ( (self=[super init]) != nil )
             {
             // [super init] did basic initialization
             // do more initialization with param here
             iVar = param;
             ...

You can perfectly well call init (or more properly, the designated
initializer, whatever it happens to be) in the same class, as long as the
super class init (or designated initializer) is called before the real setup
starts.

You can do what ever you like, but usually initWithParam will not call init, but the other way around:


init will call initWithParam: and initWithParam: will call initWithParam:other: which will call the super designated initializer.
