如何在导航栏上使用图像徽标而不是标题 [英] How to use an image logo on the navigation bar instead of title

问题描述

我尝试了几个不同的代码，但无法显示徽标

I have tried a couple different codes but couldn't make the logo show

import UIKit 
class HomeViewController: UIViewController { 

override func viewDidLoad() { 
super.viewDidLoad() 

let logo = UIImage(named: "logo.png") 
let imageView = UIImageView(image: logo) 
self.navigationItem.titleView = imageView
navigationItem.titleView?.sizeToFit() 
 } 
}

我什至试图在课程中包含 IB 本身也没有用，它似乎不是那样工作

I even tried to include IB in the class itself didn't work either, it doesn't seem to work that way

@IBOutlet weak var navBar: UINavigationItem!

附注.我的徽标是一个 200x40px 的 png，它在资产中命名为 logo.png.

PS. My logo is a 200x40px png and its named logo.png in the assets.

感谢任何帮助

我通过在那里放置一个图像视图而不是整个导航项故事来解决我的问题.不过还是谢谢你的建议.

I solved my problem by putting an image view there instead of this whole navigation item story. Thanks for your suggestions though.

推荐答案

试试这个

 let logo = UIImage(named: "logo.png") 
 let imageView = UIImageView(image: logo) 
 imageView.contentMode = .ScaleAspectFit // set imageview's content mode
 self.navigationItem.titleView = imageView
