Can't load table view contains on UIViewController

[mrjimoy]

Hi, is it possible to load a view controller that contains a table view as a pop-up? I tried to load it but the table view doesn't get rendered. I am not attaching any code here. Please confirm. Thanks.

Best regards,
Jimmy

Hi @mrjimoy,

I am not sure if I understood you correctly, but did you have a look at the example provided in #87? This is an example of a custom view containing a table view used with PopupDialog. It is not using Storyboard or XIBs, however the RatingDialog in the very example of the PopupDialog repo is using a custom view controller with XIBs.

With table views and any kind of scroll views, you have to set a fixed height on them. Always make sure the constraints are satisfied.

Cheers

Hi @mwfire,

Thanks for your reply.

I mean I tried to show a custom UIViewController that contains UITableView, but the UITableView didn't showed up on the page. Please see code/images below for more details (I omit some code to simplify).

This is the UIViewController that need to be loaded on the page as a pop-up:

And this is what I get (only show the button part which is under UIViewController) :

This is the code to show the pop-up:

- (void)showPopup {
    
    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"StoryBoard" bundle:nil];
    FormViewController *viewController = (FormViewController *) [storyBoard instantiateViewControllerWithIdentifier:@"CodeForm"];
//    viewController.modalPresentationStyle = UIModalPresentationCustom;

    PopupDialog *popup = [[PopupDialog alloc] initWithViewController:viewController
                                                     buttonAlignment:UILayoutConstraintAxisHorizontal
                                                     transitionStyle:PopupDialogTransitionStyleBounceUp
                                                    gestureDismissal:YES
                                                          completion:^{
                                                              // What to do when the popup closed
                                                              
                                                              
                                                          }];
    
    [self presentViewController:popup animated:YES completion:nil];
    
}

And this is the custom UIViewController's code:

@objc class FormViewController: UIViewController {

    @IBOutlet weak var tableView: UITableView!
    
    @IBOutlet weak var sendVerifyCodeButton: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Hide navigation bar
        navigationController?.isNavigationBarHidden = true
        
        // UITableView properties
        let identifier = NSStringFromClass(UITableViewCell.self)
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: identifier)
        tableView.delegate = self
        tableView.dataSource = self
        tableView.tableFooterView = UIView.init(frame: CGRect.zero)
        tableView.tableFooterView!.isHidden = true
    }

}

extension FormViewController: UITableViewDataSource {
    
    // MARK: - Table view data source
    
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 9
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        return UITableViewCell()
    }
    
    
    // MARK: - Appearance
    
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableViewAutomaticDimension
    }
    
    func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
        return UITableViewAutomaticDimension
    }    
}

I have set the constraint properly but still. Do I miss something?

Thanks.

Btw I tried to set the height of tableview on the storyboard, and it work. When I tried to set the height of the tableview programatically under viewDidAppear's method, it doesn't work..

[mwfire]

@mrjimoy, when programatically setting constraints of a view controller that has a storyboard or XIB related view, make sure to also set the translatesAutoresizingMaskIntoConstraints property of the corresponding view to false upfront.

@mwfire cool, it works :) thanks..
