目前小 viewController

Question

问题状态：我有两个 viewController

parentViewController (375 * 667)
childViewController (300 * 667)

我想在 Axis (75 * 0) 处显示 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

一样伸展自己

谁能帮我解决这个问题？谢谢

Answer 1

通过设置preferredContentSize 属性将解决您的问题，请尝试下面的代码片段

newVC?.preferredContentSize = CGSize(width: 300, height: 667)

Answer 2

你在哪里设置你的 ViewController 的框架？如果您使用的是自动布局，则需要设置约束以使 ViewController 看起来像您想要的那样。如果您想以编程方式进行，您可以在某处设置框架，例如在您上面发布的代码中，您可以这样做：

@IBAction func btnShowVC(_ sender: UIButton) {
   let storyboard = UIStoryboard(name: "Main", bundle: nil)
   let newVC = storyboard.instantiateViewController(withIdentifier: "cvc") as? childViewController
   newVc.view.frame = CGRect(x: 75, y: 0, width: 300, height: 667)
   self.present(newVC!, animated: true, completion: nil)
}

Answer 3

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)
