ios - 呈现小 viewController

Question

问题状态:我有两个 viewController

1. parentViewController (375 * 667)
2. childViewController (300 * 667)

我想在 Axis (75 * 0) 处呈现 childViewController，如下所示

childViewController 显示在这个 IBAction 上

@IBAction func btnShowVC(_ sender: UIButton) {
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let newVC = storyboard.instantiateViewController(withIdentifier: "cvc") as? childViewController
    self.present(newVC!, animated: true, completion: nil)
}

但它像这样拉伸(stretch)自己

谁能帮我解决这个问题？谢谢

你可以这样试试。

let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let newVC = storyboard.instantiateViewController(withIdentifier: "ChildViewController") as? ChildViewController
            view.addSubview((newVC?.view)!)
        newVC?.view.frame = CGRect(x:75,y:0,width:view.frame.size.width-75,height:view.frame.size.height)
        newVC?.view.autoresizingMask = \[.flexibleWidth, .flexibleHeight\]


        newVC?.didMove(toParentViewController: self)
