使用多个字符串创建 onDoneBlock
Creating onDoneBlock with multiple strings
在我的应用程序中,我将锻炼存储为 NSDictionary(练习、组、次数、公斤和笔记),但我想将每个人存储为一个字符串。我有自己的 class 用于创建锻炼 (ExerciseCreator.swift)。 onDoneBlock 是这样的:var onDoneBlock : ((NSDictionary) -> Void)?
现在代码是这样使用的:
//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 来完成相同的操作?
您可以像下面这样更新您的块声明
var onDoneBlock : ((Array<Any>) -> Void)?
同时更新参数名称如下
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"])
}
希望这对您有所帮助!
