无法赋值类型'[uiimage]的值？键入uiimage（swif3）

Question

我试图保存2 uiimages在一起，然后把组合图像，并让它等于名为finalImage的图像视图。但是，我收到错误消息，我已将标题分配给我的问题。只是想把图像视图中的组合uiimage。

@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 

    }

您newImage是UIImage的，所以就把

finalImage.image = newImage 

，因为，你有UIImage类型，而不是[UIImage] - 阵列的UIImage对象，在finalImage.image
