How to display a hidden part just under the Submit button after clicking?


So, I'm trying to make a hidden part visible after clicking the submit button. More specifically, this part should be a TableView that will display user selections/entries before they hit the submit button. Is there a way to do that?

Please see the images as examples.

I have tried to use ExpandableTableViewController 2.0 in CocoaPods. It uses a Tableview Controller to make table cells expandable. However, I couldn't figure out how to implement/connect it into my ViewController. If you have a better way to do it, please let me know!

Thank you in advance for your help!

You can also manage the height constraint of UITableView's in your code to get the expand/collapse effect

Here is the sample code

@interface ViewController ()
    BOOL toggleToshow;
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *heightConstraintTbl;

- (IBAction)btnSubmitClicked;


@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    toggleToshow = YES;
    self.heightConstraintTbl.constant = 0;


- (IBAction)btnSubmitClicked {

    [UIView animateWithDuration:1 animations:^{
        self.heightConstraintTbl.constant = toggleToshow?285:0;

        toggleToshow = !toggleToshow;

        [self.view layoutIfNeeded]; // Make sure to Call this for getting nimation effect


Here is the swift version

import UIKit

class AnimateViewController: UIViewController {

    var toggleToshow = true;

    @IBOutlet weak var heightConstraintTbl: NSLayoutConstraint!

    @IBAction func btnSubmitClicked() {

        UIView.animateWithDuration(1, animations: { () -> Void in

            if self.toggleToshow{
                self.heightConstraintTbl.constant = 285
                self.heightConstraintTbl.constant = 0

            self.toggleToshow = !self.toggleToshow

            self.view.layoutIfNeeded(); // Make sure to Call this for getting nimation effect

    override func viewDidLoad() {

        toggleToshow = true;
        self.heightConstraintTbl.constant = 0;

        // Do any additional setup after loading the view.

Happy coding...
