ios - 为什么SVProgressHUD会抛出eorrr？

Question

我正在尝试集成 SVProgressHUD 库，并希望在我的控制器上的 API 响应之前显示我已经编写了一个代码，但它抛出了一个错误，如Thread 1: "-[MYOWEB.AppDelegate window]: unrecognized selector sent to instance 0x600001bc2a40 "

//ViewController.swift

import UIKit
import SVProgressHUD
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        SVProgressHUD.setDefaultMaskType(.clear)
        SVProgressHUD.setDefaultStyle(.custom)
        SVProgressHUD.setForegroundColor(UIColor.white)
        SVProgressHUD.setBackgroundColor(#colorLiteral(red: 0.1333333333, green: 0.3764705882, blue: 0.9960784314, alpha: 1).withAlphaComponent(1))
    }


}

我的猜测是您的 AppDelegate.swift 没有 window 属性。即'让窗口; UIWindow' 该库依赖于它，请参见此处的第 72 行 https://github.com/SVProgressHUD/SVProgressHUD/blob/master/SVProgressHUD/SVProgressHUD.m
