Question

I have a constructor like this:

-(id) init 
{
    // do something here...not sure what yet  :)
}

I can instantiate objects of this class just fine, but I was getting errors calling method on this class. Why is that the case? What am I missing here? Should I have called the superclass constructor? Or is there a memory issue somehow?

Thanks!

Answer 1

What am I missing here?

You are missing a call to the designated initializer of the superclass, an assignment to self, and a return statement.

Your minimal unfinished constructor should look like this:

-(id) init 
{
    if (self=[super init]) {
        // do something here...not sure what yet  :)
    }
    return self;
}
