如何發送使用結構實例賽格瑞

Question

準備比方說，我有

struct cat { 
var paws: int 
var name: string 
var breed: string 

}

我將如何去segueing一個實例到一個新的目標控制器？特別是，從陣列到新DC的這個實例？

prepare for segue 

{ 
if segue.identifier == "segue" 
var nextVC = segue.desitnationviewcontroller as ... 
nextvc.instance = ? 

}

你可以只給它分配是這樣的：

let someCat = cat(paws: 4, name: "Kitty", breed: "Unknown") 
let arrayCat = [cat(paws: 5, name: "Mutant", breed: "Unknown"), 
       cat(paws: 4, name: "John", breed: "Doe")] 

var nextVC = segue.desitnationviewcontroller as SomeViewController 
nextVC.somePropertyName = someCat // or arrayCat if you're using an array 

在你SomeViewController，你必須有cat類型的屬性，你可以直接分配給它。例如：

class SomeViewController: UIViewController { 
    var somePropertyName: cat? // [cat]() if it's an array of type cat 
} 

此外，爲了您的方便，我添加了一個鏈接到Apple的Swift文檔。鏈接是here。
