ios - Swift 4 present view controller black screen

问题描述

I'm presenting another view controller like this:

func goToScreen(id : String) {
    let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let newViewController = storyBoard.instantiateViewController(withIdentifier: id)
    self.present(newViewController, animated: true, completion: nil)
}

The problem is, there is a cc. 1 second delay between the appearance of the new viewcontroller, and in the meantime the app shows an all black screen. Why is that? It looks really ugly

解决方案

在移动到下一个视图控制器时将动画状态更改为 false，这将消除延迟。延迟仅因动画而发生：是的。使用以下代码解决您的问题

self.present(newViewController, animated: false, completion: nil)

希望对你有帮助
