我试图通过单元格的“编辑”表视图行操作将数据从表视图单元传递到另一个视图控制器。
override func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let edit = UITableViewRowAction(style: .normal, title: "Edit") { (action, indexPath) in
let editViewController = self.storyboard?.instantiateViewController(withIdentifier: "EditViewController") as! EditViewController
self.present(editViewController, animated: true, completion: nil)
let cell = self.recipeList[indexPath.row] as? RecipeTableViewCell
editViewController.nameTextField.text = cell?.recipeNameLabel.text
}
edit.backgroundColor = UIColor(red: 167.0/255.0, green: 204.0/255.0, blue: 181.0/255.0, alpha: 1.0)
return [edit]
}
这是我的行行为函数的单元格...
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "RecipeCell", for: indexPath) as! RecipeTableViewCell
let recipe = recipeList[indexPath.row]
cell.recipeNameLabel!.text = recipe.name
cell.ratingControl.rating = recipe.rating
}
return cell
}
最佳答案
而不是传递目标VC中的每个值,而是尝试仅传递recipe
对象。然后从该对象获取值并填写控件。
1)在recipe
中创建EditViewController
对象
var editRecipe : Recipe! // Your Model class
2)赋值
let editViewController = self.storyboard?.instantiateViewController(withIdentifier: "EditViewController") as! EditViewController
editViewController. editRecipe = recipeList[indexPath.row]
self.present(editViewController, animated: true, completion: nil)
3)在
ViewDidload
的EditViewController
中if editRecipe != nil {
//Fill data in lbls
//lbl_name.text = editRecipe.name
}
