Try to do the following for all UITableViewController, I tried it and it works for me!

- (void)setSize:(BOOL)fake
{
    CGSize view_size;
    int sections_height, rows_height;

    //if you dynamically change the number of visible rows
    //for example overriding numberOfRowsInSection:section
    //this can help you to evaluate the correct popover height
    int sections = [self.tableView numberOfSections];
    int rows = 0;
    for(int i = 0; i < sections; i++){
        rows += [self.tableView numberOfRowsInSection:i];
    }
    sections_height = sections * 30 /*section height*/;
    rows_height = rows * 44 /*row height*/;

    view_size = CGSizeMake(320 /*fixed width*/, sections_height + rows_height);

    if(fake){
        view_size.width -= 1;
        view_size.height -= 1;
    }

    [self setContentSizeForViewInPopover:view_size];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    //...    
    [self setSize:FALSE];
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self setSize:TRUE];
}

- (void)viewDidAppear:(BOOL)animated
{
    [self setSize:FALSE];
    [super viewDidAppear:animated];
}
