如何在swift中使两个UIImage大小相同？

Question

我想将“yellow_noise.png”的大小与UIImagePickerController中“pickedImage”的大小相匹配。我该怎么办？

    originalImageView.image = pickedImage
    overayImageView.image = UIImage(named:"yellow_noise.png")

Answer 1

也许你可以这样做：

let overlayImageView = UIImageView(frame: originalImageView.frame)
overlayImageView.image = UIImage(named:"yellow_noise.png")
