Swift - 带有图像的 UIAlert [英] Swift - UIAlert with image

问题描述

我有这个代码:

var zdjecieGlowne: UIImage? = nil
let alert = UIAlertController(title:"MyTitle", message: "My Message Box ", preferredStyle: UIAlertControllerStyle.alert)
let saveAction = UIAlertAction(title: "MyTitle", style: .default, handler: nil)
//saveAction.setValue(UIImage(named: "logo")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal), forKey: "image")
saveAction.setValue(zdjecieGlowne, forKey: "image")
dump(zdjecieGlowne)
alert.addAction(saveAction)
alert.addAction(UIAlertAction(title: "Option 1", style: UIAlertActionStyle.default, handler: { alertAction in
    //alert.dismiss(animated: true, completion: nil)
    print("1 pressed")
}))

alert.addAction(UIAlertAction(title: "Option 2", style: UIAlertActionStyle.default, handler: { alertAction in
    //alert.dismiss(animated: true, completion: nil)
    print("2 pressed")
}))
alert.addAction(UIAlertAction(title: "Option 3", style: UIAlertActionStyle.default, handler: { alertAction in
    //alert.dismiss(animated: true, completion: nil)
    print("3 pressed")
}))

self.present(alert, animated: true, completion: nil)

因此，我收到带有蓝色背景而不是图片的警报.为什么会这样?

As a result, I receive Alert with a blue background instead of a picture. Why is it like that?

推荐答案

在 swift 中试试下面的代码

Try the below code in swift

saveAction.setValue(UIImage(named: "name.png").withRenderingMode(UIImageRenderingMode.alwaysOriginal), forKey: "image")

或者试试这个

saveAction.setValue(zdjecieGlowne.withRenderingMode(UIImageRenderingMode.alwaysOriginal), forKey: "image")
