ios - 无法更改 iOS 11 中的导航栏项目高度

Question

自定义导航栏高度大于默认值(44pt)后，我想更改右侧导航栏项目按钮的高度，但限制在44pt。我怎样才能让它长得更高？我知道在 iOS 11 中，按钮现在位于 UIBarButtonStackView 中，似乎我们无法更改堆栈 View 框架？

我使用这段代码来改变按钮的宽度和高度:

button.widthAnchor.constraint(equalToConstant: 40).isActive = true
button.heightAnchor.constraint(equalToConstant: 60).isActive = true
button.translatesAutoresizingMaskIntoConstraints = false
button.setImage(image, for: .normal)

let barButton = UIBarButtonItem(customView: button)
self.navigationItem.rightBarButtonItem = barButton

谢谢!

您可以使用此代码更改导航栏按钮项的宽度 -

override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            var frame: CGRect? = navigationItem.leftBarButtonItem?.customView?.frame
            frame?.size.width = 5  // change the width of your item bar button
            self.navigationItem.leftBarButtonItem?.customView?.frame = frame!
        }
        override var prefersStatusBarHidden : Bool {
            return true
        }
