I have a subclass of UIButton called INMenuCard and I am overriding the initWithFrame to include an activity indicator. The menuCard places correctly but any internal reference to "frame" give me "inf,inf,0,0" which means my activityIndicator subview is not placed correctly. What might I be missing?

@implementation INMenuCard

- (id)initWithFrame:(CGRect)frame 
{
    if (self = [super initWithFrame:frame]) 
    {

        CGRect innerFrame = CGRectInset(frame, 50.0f, 100.0f);
        activityIndicator = [[UIActivityIndicatorView alloc]
                             initWithFrame:innerFrame];
        activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
        [self addSubview:activityIndicator];
    }
    return self;
}

I am instantiating INMenuCard with (debugging shows the CGRect values are correct):

 CGRect cardFrame = CGRectMake(cardX, cardStartY, cardWidth, cardHeight);
 INMenuCard *menuCard = [[INMenuCard buttonWithType:UIButtonTypeCustom] initWithFrame:cardFrame];
 [theView addSubView:menuCard];
