iOS Swift手势:如何使用手势链接两个项目

import UIKit

class ViewController: UIViewController {
    
    let view1 = UIView()
    let view2 = UIView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置视图属性
        view1.backgroundColor = .blue
        view2.backgroundColor = .red
        
        // 添加视图到主视图
        view.addSubview(view1)
        view.addSubview(view2)
        
        // 设置布局约束
        view1.translatesAutoresizingMaskIntoConstraints = false
        view2.translatesAutoresizingMaskIntoConstraints = false
        
        NSLayoutConstraint.activate([
            view1.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            view1.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: -50),
            view1.widthAnchor.constraint(equalToConstant: 100),
            view1.heightAnchor.constraint(equalToConstant: 100),
            
            view2.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            view2.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 50),
            view2.widthAnchor.constraint(equalToConstant: 100),
            view2.heightAnchor.constraint(equalToConstant: 100)
        ])
        
        // 创建点击手势识别器
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
        
        // 将手势识别器添加到view1
        view1.addGestureRecognizer(tapGesture)
        view1.isUserInteractionEnabled = true // 确保视图可以接收手势
        
        // 初始时隐藏view2
        view2.isHidden = true
    }
    
    @objc func handleTap(_ gesture: UITapGestureRecognizer) {
        // 当view1被点击时，切换view2的显示状态
        view2.isHidden.toggle()
    }
}
