问题描述
我希望显示的视图控制器VC2的尺寸比屏幕小，如何在Swift 3中进行操作?感谢帮助. 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)
}
推荐答案
尝试这个..
@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.这是一个关于容器视图的绝佳教程: https://cococoacasts. com/manding-view-controllers-with-container-view-controllers/

You can simply use a container view to display the smaller view controller. Here is a great tutorial on container views: https://cocoacasts.com/managing-view-controllers-with-container-view-controllers/
