ios - 向 alertcontroller 中的按钮添加功能

Question

我是 swift 的新手，我在警报 View 类(class)中遵循了一些教程。我想添加功能，例如在单击警报按钮时调用另一个 View Controller ，但我不知道如何。所以请帮助我

    func showAlertController(){

    var title : String = "hi!"
    var message : String = NSLocalizedString("Are you feeling well? ", comment:"")
    let cancelButtonTitle = NSLocalizedString("No", comment:"")
    let otherButtonTitle = NSLocalizedString("Yes", comment:"")

    let alertController = UIAlertController(title: title, message: message, preferredStyle: .Alert)

    let cancelAction = UIAlertAction(title: cancelButtonTitle, style: .Cancel){
        action in NSLog("No!!!!")
    }

    let otherAction = UIAlertAction(title: otherButtonTitle, style: .Default){
        action in NSLog("welcome!!! hello back")
    }

    alertController.addAction(cancelAction)
    alertController.addAction(otherAction)
    presentViewController(alertController, animated: true, completion: nil)
}

Answer 1

试试这段代码:

let cancelAction = UIAlertAction(title: cancelButtonTitle, style: .Cancel){
        action in NSLog("No!!!!")
        let View2 = self.storyboard?.instantiateViewControllerWithIdentifier("View2") as TwoViewController
        self.navigationController?.pushViewController(View2, animated: true)
        
    }

并选择您现有的 View Controller ，然后从下拉菜单中选择编辑>嵌入 > 导航 Controller 。

之后添加一个新的 View Controller 并创建一个新的 Cocoa 类并将其命名为 TwoViewController SubClass of UIViewController .

之后选择您的新 ViewController 并从 Identity Inspector 以这种方式自定义它

也许这可以帮到你。
