ios swift：如何在动态tableview中拥有一个静态单元格？

Question

I would like to use a tableView to have 2 static cells on top of a list of dynamic cells. As far as I understand, I have to use a dynamic prototype tableView. But I don't understand how to add 2 static cells and design them, eg. adding a textfield to the first and a label to the second.

What do I have to do in my storyboard? And what do I have to do inside the Controller? How can I differentiate the static from the dynamic cells?

Could someone give me as a bloody beginner some guidance where to start? Thanks so much!!

EDIT: I tried this for testing:

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 5
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cardCell", forIndexPath: indexPath) as CardTableViewCell

    //static cell
    if (indexPath.row < 2) {
        cell.dyn.text = "static \(indexPath.row)"
        return cell;
    }

    // Configure the cell...
    cell.dyn.text = "buh"

    return cell
}

this results in this:

Later when I use real data I will miss the first 2 data rows... Can I somehow "reset" the row counter after I created my static cells?

And how can I modify the 2 static cells? For adding a textfield and labels? Or do I have to do this programmatically?

I found help here: Mixing static and dynamic sections in a grouped table view

And my solution looks like this:

1.

2. Add and layout the static cells:

3. Give each cell a unique name and add them as outlet to the TableViewCell class

4. Adjust the code:

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 3 } override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { if (section == 2){ // my dynamic cell is index 2 return 5 // just for testing, add here yourrealdata.count } return 1 // for static content return 1 } override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { var cell: CardTableViewCell! if (indexPath.section == 0) { cell = tableView.dequeueReusableCellWithIdentifier("static1", forIndexPath: indexPath) as CardTableViewCell cell.cardSetName?.text = self.cardSetObject["name"] as String }else if (indexPath.section == 1) { cell = tableView.dequeueReusableCellWithIdentifier("static2", forIndexPath: indexPath) as CardTableViewCell // just return the cell without any changes to show whats designed in storyboard }else if (indexPath.section == 2) { cell = tableView.dequeueReusableCellWithIdentifier("cardCell", forIndexPath: indexPath) as CardTableViewCell cell.dyn.text = "row \\(indexPath.row)" // return test rows as set in numberOfRowsInSection } return cell; } 

End results will look like this:

I hope I can help someone with the same question :)

Answer 2

you could use something like this to use or display your static cell

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return numberOfDynamicCells + 1;
}

and in you cellForRowAtIndexPath datasource you may use something like this.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 0){
// go ahead to display your static Cell
}
else{
//go ahead to display your dynamic cells.
}
return yourCell;
}

here is code for swift.

func numberOfRowsInSection(_ section: Int) -> Int{
return numberOfDynamicCells + 1
}

and in you cellForRowAtIndexPath datasource you may use something like this.

func cellForRowAtIndexPath(_ indexPath: NSIndexPath) -> UITableViewCell?{
if indexPath.row = 0{
// go ahead to display your static Cell
}
else{
//go ahead to display your dynamic cells.
}
return yourCell;
}

Good Luck...

Yes you can by having static cells be IBOutlet properties and in the tableView(_:cellForRowAt:) you can return those properties for any index paths you want

Here's an example:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
  switch indexPath.row {
  case 0:
    return firstStaticCell
  case 1:
    return secondStaticCell
  default:
    let cell = tableView.dequeueReusableCell(withIdentifier: "DynamicCell", for: indexPath)

    cell.textLabel?.text = "Dynamic \(indexPath.row + 1)"
    return cell
  }
}
