creating custom tableview cells in swift

Question

I have a custom cell class with a couple of IBOutlets  I have added the class to the storyboard  I have connected all my outlets  my cellForRowAtIndexPath function looks like this   override func tableView tableView  UITableView   cellForRowAtIndexPath indexPath  NSIndexPath   - gt  UITableViewCell            let cell   tableView dequeueReusableCellWithIdentifier  Cell   forIndexPath  indexPath  as SwipeableCell          cell mainTextLabel text   self venueService mainCategoriesArray   indexPath row           return cell         Here is my custom cell class   class SwipeableCell  UITableViewCell        IBOutlet var option1  UIButton      IBOutlet var option2  UIButton      IBOutlet var topLayerView   UIView      IBOutlet var mainTextLabel   UILabel      IBOutlet var categoryIcon   UIImageView      init style  UITableViewCellStyle  reuseIdentifier  String             super init style  style  reuseIdentifier  reuseIdentifier              When I run the app  all my cell are empty  I have logged out self venueService mainCategoriesArray   and it contains all the correct strings  I have also tried putting an actual string equal to the label  and that produces the same result    What am I missing  Any help is appreciated

Uncheck  Size Classes  checkbox works for me as well  but you could also add the missing constraints in the interface builder  Just use the built-in function if you don t want to add the constraints on your own  Using constraints is - in my opinion - the better way because the layout is independent from the device  iPhone or iPad

1  First Design your tableview cell in StoryBoard    2   Put below table view delegate method    MARK  - Tableview Delegate Methods  func numberOfSectionsInTableView tableView  UITableView  - gt  Int       return 1    func tableView tableView  UITableView  numberOfRowsInSection section  Int  - gt  Int        return  lt    Your Array    gt      func tableView tableView  UITableView  heightForRowAtIndexPath indexPath  NSIndexPath  - gt  CGFloat        var totalHeight   CGFloat    lt cell name gt   lt label name gt  frame origin y          totalHeight      UpdateRowHeight  lt cell name gt   lt label name gt   textToAdd   lt your array gt  indexPath row            return totalHeight     func tableView tableView  UITableView  cellForRowAtIndexPath indexPath  NSIndexPath  - gt  UITableViewCell         var cell    lt cell name gt     tableView dequeueReusableCellWithIdentifier     lt cell identifire gt      forIndexPath  indexPath  as  CCell VideoCall      if cell    nil                cell   NSBundle mainBundle   loadNibNamed   lt cell identifire gt    owner  self  options  nil  0  as   lt cell name gt                lt cell name gt   lt label name gt  text    lt your array gt  indexPath row  as  String        return cell as  lt cell name gt        MARK  - Custom Methods  func UpdateRowHeight   ViewToAdd   UILabel   textToAdd   AnyObject    - gt  CGFloat        var actualHeight   CGFloat   ViewToAdd frame size height      if let strName   String     textToAdd as  String          where  strName  isEmpty                actualHeight   heightForView1 strName   font  ViewToAdd font  width  ViewToAdd frame size width  DesignTimeHeight  actualHeight              return actualHeight

I have the same problem   Generally what I did is the same as you   class dynamicCell  UITableViewCell         IBOutlet var testLabel   UILabel      init style  UITableViewCellStyle  reuseIdentifier  String            super init style  style  reuseIdentifier  reuseIdentifier             override func awakeFromNib             super awakeFromNib              override func setSelected selected  Bool  animated  Bool            super setSelected selected  animated  animated            and in the uitableviewcell method   func tableView tableView  UITableView   cellForRowAtIndexPath indexPath  NSIndexPath   - gt  UITableViewCell        var cell  dynamicCell   tableView dequeueReusableCellWithIdentifier  cell   as dynamicCell      cell testLabel text    so sad       println cell testLabel       return cell      and yeah the tableview shows nothing  But guess what  it actually shows something   because the log I get from the println cell testLabel  shows that all the Labels are actually displayed out   BUT  their Frames is strange  which have something like this      frame    0 -21  42 21     so it has a  0 -21  as  x y   so that means the label just appears at somewhere outside the bound of the cell   so I try to add adjust the frame manually like this      cell testLabel frame   CGRectMake 10  10  42  21    and sadly  it doesn t work   ---------------update after 10 min -----------------  I DID IT  so  it seems that the problem comes from the Size Classes   Click on your  storyboard file and go to the File Inspector Tab  UNCHECK THE Size Classes checkbox  and finally  my  so sad Label comes out

Thanks for all the different suggestions  but I finally figured it out  The custom class was set up correctly  All I needed to do  was in the storyboard where I choose the custom class  remove it  and select it again  It doesn t make much sense  but that ended up working for me

Custom Table View Cell Example Tested with Xcode 9  edit also tested on 11   12 Beta 2  and Swift 4  edit  also tested on 5 2  The asker of the original question has solved their problem  I am adding this answer as a mini self contained example project for others who are trying to do the same thing  The finished project should look like this   Create a new project It can be just a Single View Application  Add the code Add a new Swift file to your project  Name it MyCustomCell swift  This class will hold the outlets for the views that you add to your cell in the storyboard  import UIKit class MyCustomCell  UITableViewCell        IBOutlet weak var myView  UIView       IBOutlet weak var myCellLabel  UILabel     We will connect these outlets later  Open ViewController swift and make sure you have the following content  import UIKit class ViewController  UIViewController  UITableViewDelegate  UITableViewDataSource               These strings will be the data for the table view cells     let animals   String      quot Horse quot    quot Cow quot    quot Camel quot    quot Sheep quot    quot Goat quot               These are the colors of the square views in our table view cells         In a real project you might use UIImages      let colors    UIColor blue  UIColor yellow  UIColor magenta  UIColor red  UIColor brown              Don t forget to enter this in IB also     let cellReuseIdentifier    quot cell quot            IBOutlet var tableView  UITableView           override func viewDidLoad             super viewDidLoad                    tableView delegate   self         tableView dataSource   self                   number of rows in table view     func tableView   tableView  UITableView  numberOfRowsInSection section  Int  - gt  Int           return self animals count                   create a cell for each table view row     func tableView   tableView  UITableView  cellForRowAt indexPath  IndexPath  - gt  UITableViewCell                    let cell MyCustomCell   self tableView dequeueReusableCell withIdentifier  cellReuseIdentifier  as  MyCustomCell                  cell myView backgroundColor   self colors indexPath row          cell myCellLabel text   self animals indexPath row                   return cell                   method to run when table view cell is tapped     func tableView   tableView  UITableView  didSelectRowAt indexPath  IndexPath            print  quot You tapped cell number   indexPath row   quot            Setup the storyboard Add a Table View to your view controller and use auto layout to pin it to the four sides of the View Controller  Then drag a Table View Cell onto the Table View  And then drag a View and a Label onto the Prototype cell   You may need to select the Table View Cell and manually set the Row Height to something taller in the Size inspector so that you have more room to work with   Use auto layout to fix the View and the Label how you want them arranged within the content view of the Table View Cell  For example  I made my View be 100x100   Other IB settings Custom class name and Identifier Select the Table View Cell and set the custom class to be MyCustomCell  the name of the class in the Swift file we added   Also set the Identifier to be cell  the same string that we used for the cellReuseIdentifier in the code above   Hook Up the Outlets  Control drag from the Table View in the storyboard to the tableView variable in the ViewController code  Do the same for the View and the Label in your Prototype cell to the myView and myCellLabel variables in the MyCustomCell class   Finished That s it  You should be able to run your project now  Notes  The colored views that I used here could be replaced with anything  An obvious example would be a UIImageView  If you are just trying to get a TableView to work  see this even more basic example  If you need a Table View with variable cell heights  see this example
