我想要一个带有图像的简单 UIAlertController。我该怎么办？

let alertMessage = UIAlertController(title: "Service Unavailable", message: "Please retry later", preferredStyle: .Alert)
                alertMessage.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))

Answer 1

试试这个:

let alertMessage = UIAlertController(title: "Service Unavailable", message: "Please retry later", 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)
