ios - How to override both initWithFrame: and initWithCoder: in subclass of UIView?

Question

I'm trying to subclass UIView. I already have some designated initializer and I want to have possibility for my custom view to be initialized either from code or from Nib file. So, Apple told us to use designated initializer, but they are not doing it themselves - initWithCoder: doesn't call initWithFrame:. What should I do to have my designated initializer be called in both situations? Is there no way to do that?

Pack your special initialization in one method. It can be private (declared in .m). Then override both initializers and call your init-method from within them.

- (void)myInitialization
{
    //do your stuff
}

-  (id)initWithFrame:(CGRect)aRect
{
    self = [super initWithFrame:aRect];

    if (self)
    {
        [self myInitialization];
    }

    return self;
}

- (id)initWithCoder:(NSCoder*)aDecoder 
{
    self = [super initWithCoder:aDecoder];
    if (self)
    {
        [self myInitialization];
    }

    return self;
}
