在我的应用程序中,我将锻炼内容存储为NSDictionary(运动,练习,练习,公斤和音符),但是我想将每个人存储为字符串。我有一个自己的课程来创建锻炼(ExerciseCreator.swift)。 onDoneBlock就像这样:var onDoneBlock : ((NSDictionary) -> Void)?

现在代码使用如下:

//Creating a dictionary from the exercise values
var exerciseDictionary: NSDictionary!

exerciseDictionary =  ["Exercise" : exerciseNameTextField.text!, "Sets" : String(format: "%d", setCount), "Reps" : String(format: "%d", repsCount), "KG" : String(format: "%d", kgCount)]

//Closing modal and refreshing tableview on parent view controller
if let callback = self.onDoneBlock {
       callback (exerciseDictionary)
}

在我的主视图控制器中,代码如下:

let exerciseCreator = ExerciseCreator()
        exerciseCreator.viewReady = {() -> Void in}
        exerciseCreator.onDoneBlock = {(dict) -> Void in
            self.dismiss(animated: true, completion: {
                self.exercisesArray.add(dict)
                self.tableView.reloadData()
                print("Exercises: \(self.exercisesArray)")
            })
        }

如何使用字符串而不是NSDictionary完成相同的工作?

答案 0 :(得分:0)

您可以像下面一样更新块声明

var onDoneBlock : ((Array<Any>) -> Void)?

还更新如下的参数名称

self.onDoneBlock = {(arrayVal) -> Void in
      self.dismiss(animated: true, completion: {
          self.exercisesArray.add(arrayVal)
          self.tableView.reloadData()
          print("Exercises: \(self.exercisesArray)")
      })
}

并像这样传递您的数组

//Closing modal and refreshing tableview on parent view controller
if let callback = self.onDoneBlock {
      callback (arrayObject)
}

编辑:

对于像这样的字符串数组传递值

if let callback = self.onDoneBlock {
     callback (["Test1","Test2","Test3"])
}

希望这会有所帮助!
