如何更改导航栏Swift 3的高度 [英] How can I change height of Navigation Bar Swift 3

问题描述

我很确定这不是重复的，因为我查看了其他答案，它们都已过时，并没有提供确切的答案。

I'm pretty sure this is not duplicate because I looked at other answers and they all outdated and do not provide exact answer.

我有导航控制器和几个视图控制器。我想让导航栏更高一些，所以它适合我需要的文本大小。我怎样才能做到这一点 ？

I have Navigation Controller and several view controllers. I want to make Navigation Bar a bit taller so it would fit text size that I need. How can I do that ?

我试过这个：
UINavigationBar.appearance（）。frame = CGRect（x：0.0，y：0.0，width：320.0，height：210.0）但是没有任何反应...

I tried this: UINavigationBar.appearance().frame = CGRect(x: 0.0, y: 0.0, width: 320.0, height: 210.0) but nothing happens...

此外，我无法使用Xcode布局按钮向导航栏添加任何约束。

Also, I wasn't able to add any constraints to the Nav Bar using Xcode layout buttons.

希望有人能帮助我解决这个问题。提前致谢！

Hope somebody can help me to fix this issue. Thanks in advance!

推荐答案

这是一种方法：

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    let height: CGFloat = 50 //whatever height you want to add to the existing height
    let bounds = self.navigationController!.navigationBar.bounds
    self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)

}
