How to use an image logo on the navigation bar instead of title
提问by Mert Alnuaimi
I have tried a couple different codes but couldn't make the logo show
我尝试了几个不同的代码，但无法显示徽标
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()
}
}
I even tried to include IB in the class itself didn't work either, it doesn't seem to work that way
我什至试图在课程中包含 IB 本身也不起作用，它似乎不是那样工作
@IBOutlet weak var navBar: UINavigationItem!
PS. My logo is a 200x40px png and its named logo.png in the assets.
附注。我的标志是一个 200x40px 的 png，它在资产中命名为 logo.png。

Edit: I solved my problem by putting an image view there instead of this whole navigation item story. Thanks for your suggestions though.
编辑：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。谢谢你的建议。

This code looks good, i think there is error in name of UIImage, did you debug and check that let logois not nil? try to remove ".jpg"
这段代码看起来不错，我认为 UIImage 的名称有误，您是否调试并检查了let logo不是nil？尝试删除“.jpg”
