Swift模态视图控制器，透明背景超越标签栏

Question

我在gist中尝试了相同的代码：https://gist.github.com/barbietunnie/e5547f35180436ac102cac52a15f8ca3

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .OverCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

它的工作正常但是在标签栏的情况下，内容超出标签栏，我们如何才能在标签栏的上/前显示内容？

Answer 1

通过vc.modalPresentationStyle = .overFullScreen

工作

Answer 2

我希望它对你有用，

let mainStoryboard = UIStoryboard(name: "Main", bundle: nil)
let controller = mainStoryboard.instantiateViewController(withIdentifier:  "ModalViewController") as! ModalViewController
controller.modalPresentationStyle = .overCurrentContext

谢谢。
