更改UITableViewCell滑动动作标题 [英] Changing the UITableViewCell swipe action title

问题描述

我有一个标题为激活"的行动作按钮.当我按下它时，我希望标题更改为停用".

I have a row action button titled "Activate". When I press it, I want the title to change to "Deactivate".

我无法在处理程序函数中更改标题.另外，激活"和停用"应具有不同的功能.

I was unable to change the title in the handler function. Also, "Activate" and "Deactivate" should have different functions.

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {

    let account = accountTypes[indexPath.section].accounts[indexPath.row]

    let delete = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Delete", handler: { (action, indexPath) -> Void in
        // action delete
    })

    let activation = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Activate", handler: { (action, indexPath) -> Void in
        // action activate
    })
    activation.backgroundColor = UIColor.lightGrayColor()

    let arrayofactions: Array = [delete, activation]
    return arrayofactions

}

推荐答案

当要显示激活和停用时，必须手动管理每个索引路径的单元格状态. 保存单个 indexpath 的数据(条件)，并将以下条件放入您的 editActionsForRowAtIndexPath 方法中.

You have to manage your cell's state manually for each indexpath when you want to show activate and de-activate. Save data(condition) for individual indexpath and put below condition in your editActionsForRowAtIndexPath method.

let arrayofactions
if(condition true) {
  let activation = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Activate", handler: { (action, indexPath) -> Void in
    // action activate
  })
   activation.backgroundColor = UIColor.lightGrayColor()
   arrayofactions: Array = [delete, activation]
}
else {
   let deactivation = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "De-Activate", handler: { (action, indexPath) -> Void in
    // action deactivate
  })
   deactivation.backgroundColor = UIColor.lightGrayColor()
   deactivation: Array = [delete, deactivation]

}
