这是 Apple推出的屏幕指南 .

Here is the Launch Screen Guideline from Apple.

以下是启动屏幕视图"控制器的代码:

import UIKit
class LaunshViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.delay(0.4)
    }

    func delay(_ delay:Double, closure:@escaping ()->()) {
        let when = DispatchTime.now() + delay
        DispatchQueue.main.asyncAfter(deadline: when, execute: closure)
    }
}

推荐答案

在AppDelegate类中放置一行代码-

Put one line of code in AppDelegate class -

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        Thread.sleep(forTimeInterval: 3.0)
        // Override point for customization after application launch.
        return true
    }
