ios - 当我改变设备的方向时，为什么框架中的值等于特定大小不做同样的工作？

Question

我有一段代码允许我在设备方向更改期间更改 UIImageView 的大小。

我对这些值进行了硬编码(高度 = 896 和宽度 = 414)，并且效果很好，但是当我想通过放置动态值(height = self.view.frame.size. height 和 width = self.view.frame.size.width), 它不起作用...

但是，self.view.frame.size.height = 896 和 self.view.frame.size.width = 414 这很奇怪...我错过了我的想法。

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    if UIDevice.current.orientation.isLandscape {
        print("Landscape")
        self.newImageView?.frame.size.height = 414
        self.newImageView?.frame.size.width = 896
        navBar?.frame = CGRect(x: 0, y: 0, width: 896, height: 100)
    } else {
        print("Portrait")
        self.newImageView?.frame.size.height = 896
        self.newImageView?.frame.size.width = 414
        navBar?.frame = CGRect(x: 0, y: 40, width: 414, height: 100)
    }
}  

编辑(解决方案):有关信息，我在我的代码中使用了这种方式，但票证中的解决方案更短、更现代

 //Share bar
        let shareBar: UIBarButtonItem = UIBarButtonItem.init(barButtonSystemItem:.action, target: self, action: #selector(userDidTapShare))
        self.navigationItem.rightBarButtonItem = shareBar
        if UIDevice.current.orientation.isLandscape {
            let width =  max(self.view.frame.size.width, self.view.frame.size.height)
            let height = min(self.view.frame.size.width, self.view.frame.size.height)
            self.newImageView?.frame.size.height = height
            self.newImageView?.frame.size.width = width
            navBar = UINavigationBar(frame: CGRect(x: 0, y: UIApplication.shared.statusBarFrame.height, width: width, height: 100))
        } else {
            let width =  min(self.view.frame.size.width, self.view.frame.size.height)
            let height = max(self.view.frame.size.width, self.view.frame.size.height)
            self.newImageView?.frame.size.height = height
            self.newImageView?.frame.size.width = width
            navBar = UINavigationBar(frame: CGRect(x: 0, y: UIApplication.shared.statusBarFrame.height, width: width, height: 100))
        }
        view.addSubview(navBar!)

有什么想法吗？

Answer 1

如果你想调整导航栏的大小

 self.navBar.autoresizingMask = (UIView.AutoresizingMask(rawValue: UIView.AutoresizingMask.RawValue(UInt8(UIView.AutoresizingMask.flexibleRightMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleLeftMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleBottomMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleTopMargin.rawValue))))

把它放在你的 view.addSubview(navBar!) 之后
