ios - 使用自定义 init 实例化带有标识符的 View Controller

Question

如何使用 Storyboard 方法使用自定义 init 实例化自定义 ViewController 类？

如何调用ProfileViewController(userId: "abc") init？

实例化 View Controller

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let destViewController = mainStoryboard.instantiateViewControllerWithIdentifier("ProfileViewController") as UIViewController

自定义 View Controller 类

class ProfileViewController: UIViewController {

var userId = ""

init(userId: String) {
    self.userId = userId
    super.init(nibName: nil, bundle: nil)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

override func viewDidLoad() {
    super.viewDidLoad()

    let menuItem = UIBarButtonItem(image: UIImage(named: "MenuIcon"), style: .Plain, target: self, action: "menuBarButtonItemClicked")
    menuItem.tintColor = UIColor.whiteColor()
    self.navigationItem.leftBarButtonItem = menuItem
}

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

}

我认为你想做的事情是不可能的。 但是你可以做这样的事情

let destViewController = mainStoryboard.instantiateViewControllerWithIdentifier("ProfileViewController") as ProfileViewController
destViewController.userId = "abc"
