ios swift：如何在动态 tableview 中有一个静态单元格？

ios swift: How to have one static cell in a dynamic tableview?

提问by user1555112

I would like to use a tableViewto 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.

我想使用 atableView在动态单元格列表的顶部有 2 个静态单元格。据我了解，我必须使用动态原型 tableView。但我不明白如何添加 2 个静态单元格并设计它们，例如。向第一个添加文本字段，向第二个添加标签。

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?

我必须在故事板中做什么？我必须在控制器内部做什么？如何区分静态单元格和动态单元格？

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

作为一个该死的初学者，有人能给我一些从哪里开始的指导吗？非常感谢！！

EDIT: I tried this for testing:

编辑：我试过这个进行测试：

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:

这导致：

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?

稍后当我使用真实数据时，我会错过前 2 个数据行......我可以在创建静态单元格后以某种方式“重置”行计数器吗？

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

以及如何修改 2 个静态单元格？用于添加文本字段和标签？还是我必须以编程方式执行此操作？

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

我在这里找到了帮助：在分组表视图中混合静态和动态部分

And my solution looks like this:

我的解决方案如下所示：

1.

1.

1. Add and layout the static cells:

2. Give each cell a unique name and add them as outlet to the TableViewCellclass

3. 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;
   } 
   

2. 添加和布局静态单元格：

3. 给每个单元格一个唯一的名称并将它们添加为TableViewCell类的出口

4. 调整代码：

   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:

最终结果将如下所示：

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

你可以使用这样的东西来使用或显示你的静态单元格

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

and in you cellForRowAtIndexPathdatasource you may use something like this.

在你的cellForRowAtIndexPath数据源中，你可以使用这样的东西。

- (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.

这是swift的代码。

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

and in you cellForRowAtIndexPathdatasource you may use something like this.

在你的cellForRowAtIndexPath数据源中，你可以使用这样的东西。

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...

祝你好运...

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

是的，您可以将静态单元格设为 IBOutlet 属性，并且tableView(_:cellForRowAt:)您可以为您想要的任何索引路径返回这些属性

Here's an example:

下面是一个例子：

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
  }
}
