如何在iOS的垂直和水平居中将分组表格视图居中？

Question

I've been looking for a way to center a table view both vertically and horizontally but I can't seem to figure out if this is better done / possible using interface builder alone. If not what method should I override to set this in objective-c itself?

Also will this use the vertical screen size of the device so it actually centers the grouped table view on both legacy iPhone devices and the new iPhone 5?

Thank you in advance

This is what I use to get the proper centered frame. Note that the view needs to have proper springs and struts so it resizes when phone calls come in, etc:

+ (CGRect)centeredFrameForSize:(CGSize)size inRect:(CGRect)rect
{
    CGRect frame;
    frame.origin.x = rintf((rect.size.width - size.width)/2) + rect.origin.x;
    frame.origin.y = rintf((rect.size.height - size.height)/2) + rect.origin.y;

//  if(frame.origin.x < 0) frame.origin.x = 0;
//  if(frame.origin.y < 0) frame.origin.y = 0;
    frame.size = size;

    return frame;
}
