Swift定时器检查TouchesEnded

import UIKit

class ViewController: UIViewController {
    var timer: Timer?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建定时器，每0.1秒触发一次
        timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(checkTouchesEnded), userInfo: nil, repeats: true)
    }
    
    @objc func checkTouchesEnded() {
        // 在这里检查TouchesEnded事件
        if let touches = UIApplication.shared.windows.first?.rootViewController?.view?.touches {
            if touches.isEmpty {
                // 触摸事件结束，执行相应逻辑
                print("Touches ended")
                // 停止定时器
                timer?.invalidate()
                timer = nil
            }
        }
    }
}
