如何在文本视图中调整缩放UIImageView的大小，就像缩放外观一样快速？

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var textView: UITextView!
    var imageView: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIImageView对象并添加到文本视图中
        imageView = UIImageView(image: UIImage(named: "image"))
        textView.addSubview(imageView)
        
        // 添加缩放手势识别器
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(handlePinchGesture(_:)))
        imageView.addGestureRecognizer(pinchGesture)
        imageView.isUserInteractionEnabled = true
    }
    
    @objc func handlePinchGesture(_ gesture: UIPinchGestureRecognizer) {
        // 获取手势的缩放比例
        let scale = gesture.scale
        
        // 根据缩放比例调整UIImageView的大小
        let newWidth = imageView.frame.width * scale
        let newHeight = imageView.frame.height * scale
        imageView.frame.size = CGSize(width: newWidth, height: newHeight)
        
        // 重新布局文本视图中的其他内容
        textView.layoutIfNeeded()
        
        // 重置手势的缩放比例
        gesture.scale = 1.0
    }
}
