Answer 1

If you have this:

@property (nonatomic , retain ) UIPopoverController *popoverController;

the methods generated by @synthesize will be something like:

-(UIPopoverController*) popoverController
{
    return popoverController;
}

-(void) setPopoverController: (UIPopoverController*) newValue
{
    [newValue retain];
    [popoverController release];
    popoverController = newValue;
}
