How to use an image logo on the navigation bar instead of title

问题

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() 
 } 
}

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!

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

My storyboard

Any help is appreciated

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

回答1:

try this

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

回答2:

Set your imageview's content mode like,

 imageView.contentMode = .ScaleAspectFit

This code looks good, i think there is error in name of UIImage, did you debug and check that let logo is not nil? try to remove ".jpg"
