如何调整图像视图的大小以适合iPhone swift的图像和缩放

import UIKit

func adjustImageViewSizeForiPhone(imageView: UIImageView, image: UIImage) {
    let screenSize = UIScreen.main.bounds.size
    let imageWidth = image.size.width
    let imageHeight = image.size.height
    
    let scale = min(screenSize.width / imageWidth, screenSize.height / imageHeight)
    let scaledWidth = imageWidth * scale
    let scaledHeight = imageHeight * scale
    
    let x = (screenSize.width - scaledWidth) / 2
    let y = (screenSize.height - scaledHeight) / 2
    
    imageView.frame = CGRect(x: x, y: y, width: scaledWidth, height: scaledHeight)
}

// 调用示例
let imageView = UIImageView()
let image = UIImage(named: "example_image")
adjustImageViewSizeForiPhone(imageView: imageView, image: image)
