Hi,

I have this app I'm working on, which on a second view asks (textfield) the name for a button to be created on first view. After specifying the name and pressing OK button, the first view pops up (as demanded) but there's no new button, although created indeed. Can I use the following code in a second view method, to "refresh" the first view before presenting itself. What's wrong with this code? Any other approach? Thank you.

-(void)initWithView:(View1Controller *)aSuperview
{
    theSuperview = aSuperview;
}

- (IBAction)itemNameButton
{
    ...
    CGRect rectang;
    rectang = CGRectMake(0, 0, 320, 460);// just in case
    [theSuperview.view setNeedsDisplayInRect:rectang];
    ...
}

Basically what I want to do is copy the already rendered content (a PDF drawn into the UIView's graphics context using CGContextDrawPDFPage()) onto a similar UIView, without having to re render the PDF.
