Changing UIView frame size does not change UITableview frame origin y

Question

I have added a UIView on top of a tableviewcontroller in IB by dragging and dropping then I have assigned and IBoutlet to that UIView .

Problem is I have a uilabel that is dynamically changing its size , so if uilabel is short I want to make the tableview closer otherwise tableview should be not that close so I can show a very long label.

So I try to change the frame of the uiview that is on top of tableview uiview changes its frame size but tableview stays stable there.

I wan to make uitableview go down when I make UIview frame size height bigger

if ([[self agenda] getMeetingTime] != nil) {
        descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, dateLabel.frame.origin.y + dateLabel.bounds.size.height+15, self.view.frame.size.width-75, 150)];
        descriptionLabel.textColor =[UIColor colorWithRed:96/256.0 green:96/256.0 blue:96/256.0 alpha:1.0];
        descriptionLabel.font = [UIFont fontWithName:@"GillSans" size:15.0f];
        descriptionLabel.text =[[self agenda] getMeetingTime];
        descriptionLabel.backgroundColor = [UIColor clearColor];
        descriptionLabel.numberOfLines=0;
        descriptionLabel.tag=PopulateTag;

        //Calculate the expected size based on the font and linebreak mode of your label
        CGSize maximumLabelSize = CGSizeMake(709,999);

        CGSize expectedLabelSize = [descriptionLabel.text sizeWithFont:descriptionLabel.font
                                              constrainedToSize:maximumLabelSize
                                                  lineBreakMode:descriptionLabel.lineBreakMode];

        //adjust the label the the new height.
        CGRect newFrame = descriptionLabel.frame;
        newFrame.size.height = expectedLabelSize.height;
        descriptionLabel.frame=newFrame;


        if ( expectedLabelSize.height>70) {

            self.upperView.frame = CGRectMake(0, 0, self.upperView.frame.size.width, self.upperView.frame.size.height+expectedLabelSize.height+20);

        }
        else
        {
            self.upperView.frame = CGRectMake(0, 0, self.upperView.frame.size.width, self.upperView.frame.size.height+expectedLabelSize.height);
        }


        [ self.upperView addSubview: descriptionLabel];


    }


    //black line
    UIView *line = [[UIView alloc] initWithFrame:CGRectMake(10, descriptionLabel.frame.origin.y + descriptionLabel.bounds.size.height+15, descriptionLabel.frame.size.width+50, 1)];
    line.backgroundColor=[UIColor colorWithRed:164/256.0 green:165/256.0 blue:160/256.0 alpha:1.0];
    line.tag=PopulateTag;

    [self.upperView addSubview:line];

      //this does not work pushes whole view down
     //self.restOfView.frame=CGRectMake(10, line.frame.origin.y + line.bounds.size.height+1, self.upperView.frame.size.width, 600);
    [restOfView reloadData];

On IB:

This is what happens:

Tableview needs go down here

How can I solve this problem?

Firstly, I don't believe you should be subclassing a UITableViewController to achieve what you want. A UITableViewController is useful when you know that your view will only contain a UITableView , in my opinion adding anything else to one defeats the purpose.

To solve your problem though, in the bottom of your code snippet uncomment out the line where you change the frame of your tableview (assuming self.restOfView is your tableView) and instead of call [self.restOfView reloadData] call:

[self.restOfView setNeedsDisplay];

reloadData just calls the tableView data source methods again, setNeedsDisplay redraws the object. I think that will work.
