将图像添加到UIAlertController

Question

这是我的警报,完美无缺.我想在警报显示时向警报添加一个图像,如果它有所不同,我会在SpriteKit中的SKScene中.

var alertController = UIAlertController(title: "How to Skate", message: "Tap the screen to perform a trick and jump over the obsticles (You can grind on rails) The game will end when you hit a highlighted red, orange or yellow obstacle. That's it! + Image", preferredStyle: UIAlertControllerStyle.Alert)     
alertController.addAction(UIAlertAction(title: "Cool!", style: UIAlertActionStyle.Cancel, handler: nil))
self.view?.window?.rootViewController?.presentViewController(alertController, animated: true, completion: nil)

Answer 1

您可以将a UIImageView作为子视图添加到您的UIAlertController.

var imageView = UIImageView(frame: CGRectMake(220, 10, 40, 40))
imageView.image = yourImage
alert.view.addSubview(imageView)

您是这样做的UIAlertController:

let alertMessage = UIAlertController(title: "My Title", message: "My Message", preferredStyle: .Alert)

let image = UIImage(named: "myImage")
var action = UIAlertAction(title: "OK", style: .Default, handler: nil)
action.setValue(image, forKey: "image")
alertMessage .addAction(action)

self.presentViewController(alertMessage, animated: true, completion: nil)

Answer 2

    let alertMessage = UIAlertController(title: "My Title", message: "", preferredStyle: .alert)
    let action = UIAlertAction(title: "OK", style: .default, handler: nil)
    action.setValue(UIImage(named: "task1.png")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal), forKey: "image")
    alertMessage .addAction(action)
    self.present(alertMessage, animated: true, completion: nil)
