如何以更小的尺寸呈现视图控制器

Question

我想展示比屏幕更小的视图控制器vc2，如何在Swift 3中做到?？谢谢你的帮助。这是我的代码：

@IBAction func leftButtonPressed(_ sender: UIButton) {
    let vc2 = self.storyboard?.instantiateViewController(withIdentifier: "Controller2") as! ViewController2
    vc2.modalPresentationStyle = .currentContext

    present(vc2, animated: true, completion: nil)
}

Answer 1

试试这个..。

@IBAction func leftButtonPressed(_ sender: UIButton) {
    let vc2 = self.storyboard?.instantiateViewController(withIdentifier: "Controller2") as! ViewController
    vc2.providesPresentationContextTransitionStyle = true
    vc2.definesPresentationContext = true
    vc2.modalPresentationStyle=UIModalPresentationStyle.overCurrentContext
    self.present(vc2, animated: true, completion: nil)

    // Make sure your vc2 background color is transparent
    vc2.view.backgroundColor = UIColor.clear
}

您可以简单地使用容器视图来显示较小的视图控制器。这里有一个关于容器视图的很好的教程：https://cocoacasts.com/managing-view-controllers-with-container-view-controllers/
