无法分配“[UIImage]”类型的值？输入“UIImage”（swif3）

Question

我试图将 2 个 uiimages 保存在一起，然后将组合的图像放入一个名为 finalImage 的图像视图中。但是，我收到错误消息，指出我已为我的问题分配了标题。只是想将组合的 uiimage 放在图像视图中。

  @IBOutlet var finalImage: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()


    let bottomImage:UIImage = UIImage(named: "pic")!
    let topImage:UIImage = UIImage(named:"wall")!
    // Change here the new image size if you want
    let newSize = CGSize(width: bottomImage.size.width, height: bottomImage.size.height)
    UIGraphicsBeginImageContextWithOptions(newSize, false, bottomImage.scale)
    bottomImage.draw(in: CGRect(x: 0,y: 0,width: newSize.width,height: newSize.height))
    topImage.draw(in: CGRect(x: 0,y: 0,width: newSize.width,height: newSize.height), blendMode:CGBlendMode.normal, alpha:1.0)
    let newImage:UIImage = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
 //error line
   finalImage.image = newImage.images

    }

你的 newImage 是 UIImage，所以把

finalImage.image = newImage

因为，你有UIImage类型，而不是[UIImage]- UIImage 对象的数组，在finalImage.image
