Я только что клонировал проект из GitHub и добавил соответствующую папку в свой проект. Когда я запускаю свой проект, эффект анимации может отображаться нормально, но изображения в анимации не могут отображаться. Я попытался повторно клонировать полный код, но он по-прежнему делает то же самое. Я уверен, что все коды и изображения полностью клонированы.

Я добавил точку останова, понимая, что функция circleMenu никогда не вызывается. Может кто-нибудь, пожалуйста, объяснить это или, по крайней мере, сказать мне, что мне нужно написать, чтобы все было правильно?

Вот мой код:

 import UIKit

import CircleMenu

extension UIColor {
    static func color(_ red: Int, green: Int, blue: Int, alpha: Float) -> UIColor {
        return UIColor(
            red: 1.0 / 255.0 * CGFloat(red),
            green: 1.0 / 255.0 * CGFloat(green),
            blue: 1.0 / 255.0 * CGFloat(blue),
            alpha: CGFloat(alpha))
    }
}

class FirstViewController: UIViewController, CircleMenuDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate{

    @IBAction func to2(_ sender: UIButton) {
        let sb = UIStoryboard(name:"Main",bundle: Bundle.main)
        let view2 = sb.instantiateViewController(withIdentifier: "view2")
        layerTransition(animTye: .cube, subType: .ramdom, curve: .EaseInEaseOut, duration: 0.4, layer: (self.view.window?.layer)!)
        self.present(view2,animated: true,completion: nil)
    }
    //    let secondView = ViewController()
    @IBAction func toView2(_ sender: UIButton) {
        let sb = UIStoryboard(name:"Main",bundle: Bundle.main)
        let secondViewController = sb.instantiateViewController(withIdentifier: "SecondViewController")
        layerTransition(animTye: .cube, subType: .ramdom, curve: .EaseInEaseOut, duration: 0.4, layer: (self.view.window?.layer)!)
        self.present(secondViewController,animated: true,completion: nil)
    }
