    Use autoresizing correctly!

    Popover - has content size

    popoverView - its initial size should be the same as popover's content size and use UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight

    tblViewMenu- its initial size should be the same as the size of its ancestor (popoverView), again, use UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight

    Your table is not scrolling because it is so big that it doesn't needs scrolling. Only the popover is clipping it.

    CGSize contentSize = CGSizeMake(320, 320);
    
    UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, contentSize.width, contentSize.height)];
    popoverView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
    
    UITableView *tblViewMenu = [[UITableView alloc]initWithFrame:popoverView.bounds];
    tblViewMenu.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
    
    popoverContent.contentSizeForViewInPopover = contentSize;
