在点击之后但在使用IOS操作之前更改UIview颜色

import UIKit

class ViewController: UIViewController {
    
    let myView = UIView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置视图属性
        myView.frame = CGRect(x: 50, y: 100, width: 200, height: 200)
        myView.backgroundColor = .blue
        
        // 添加点击手势识别器
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(viewTapped))
        myView.addGestureRecognizer(tapGesture)
        myView.isUserInteractionEnabled = true
        
        // 将视图添加到主视图
        view.addSubview(myView)
    }
    
    @objc func viewTapped(sender: UITapGestureRecognizer) {
        // 立即更改颜色
        myView.backgroundColor = .red
        
        // 添加动画效果
        UIView.animate(withDuration: 0.3) {
            self.myView.backgroundColor = .green
        }
    }
}
