How to increase the height of navigation bar in Xcode?
提问by Mayur Tolani
I'm working on a app, in which I need to keep a navigation bar. when I write any title on the bar, the time and the title kinda get very close to each other. I wanted to increase the height of the bar, so it can get some breathing room.
我正在开发一个应用程序，我需要在其中保留一个导航栏。当我在栏上写任何标题时，时间和标题会变得非常接近。我想增加酒吧的高度，这样它就可以获得一些喘息的空间。

Add the following extension to your project:
将以下扩展添加到您的项目中：
import UIKit
extension UINavigationBar {
override open func sizeThatFits(_ size: CGSize) -> CGSize {
return CGSize(width: UIScreen.main.bounds.size.width, height: 80.0)
}
}

Add this in viewWillAppearmethod
在viewWillAppear方法中添加这个
CGFloat height = 80;
[self.navigationController.navigationBar setFrame:CGRectMake(0, 0,
self.view.frame.size.width,height)];
if it increase first and shrinks to original height then add this code in viewDidAppearmethod
如果它首先增加并缩小到原始高度，则在viewDidAppear方法中添加此代码

We need to change the height of the navigation bar for each time the view show.So put the code on viewWillAppear
每次view显示的时候都需要改变导航栏的高度，所以把代码放在viewWillAppear上
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: 80)
}
we can set the width as the width of the view and change the height as we wish.
我们可以将宽度设置为视图的宽度并根据需要更改高度。

You can't change the height of the default NavigationBarif I'm not wrong.
NavigationBar如果我没记错的话，你不能改变默认的高度。
Although, you can create a custom NavigationBarand add a custom height to it.
虽然，您可以创建自定义NavigationBar并为其添加自定义高度。
回答by George Bafaloukas
I would hide the navigation bar and implement a custom one on my own. That way you could style it exactly as you want.
我会隐藏导航栏并自己实现一个自定义的。这样你就可以完全按照你的意愿设计它。
