我想知道如何在Swift中转换Int数组中的String.在Java中,我总是这样做:

String myString = "123456789";
int[] myArray = new int[myString.lenght()];
for(int i=0;i<myArray.lenght;i++){
   myArray[i] = Integer.parseInt(myString.charAt(i));
}

如何在swift中的myClass2另一个类myClass中为类中的变量添加值？

我已经尝试了类似的东西myClass2().myvariable = "value",但这没有用; 我的变量值仍然是nil.这是代码:

myViewController2:

import UIKit

class MyViewController2: UIViewController {

    var myVariable : String?;

    @IBOutlet weak var display: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func showPressed(sender: AnyObject) {
        display.text = myVariable;
    }

}

视图控制器:

import UIKit

class ViewController: UIViewController {

    let myClassInstance = myViewController2(); …
