ViewController-全屏

这是iOS 13的变化。用户将开始期待能够刷走情态动词,因此可能值得研究支持它。

如果您真的打算使用旧的演示样式,可以在演示之前设置演示视图控制器的modalPresentationStyle:

vc.modalPresentationStyle = .fullScreen

或者在视图控制器本身中覆盖它:

override var modalPresentationStyle: UIModalPresentationStyle {
    get { .fullScreen }
    set { assertionFailure("Shouldnt change that 😠") }
}

或者在情节提要中设置:

遇到了同样的问题。覆盖UIViewController实现中的“准备就绪”序列。设置navigationController。modalPresentationStyle to。全屏

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  // Get the presented navigationController and the view controller it contains
  let navigationController = segue.destination
    navigationController.modalPresentationStyle = .fullScreen
}
