【问题描述】：

所以我有以下

let profilepicURl = "https://graph.facebook.com/\(user_id_fb)/picture?type=large" //user_id_fb like 1251246454544 your facebook ID

但我想要做的是将该 url 图像放在下图的位置，我认为我可以使用 import Kingfisher，因为我已经将它与应用程序集成，但我不确定如何实现我想要的。

// Image needs to be added to project.
         let buttonIcon = UIImage(systemName: "person.circle")

        let rightBarButton = UIBarButtonItem(title: "Person", style: UIBarButtonItem.Style.done, target: self, action: #selector(FirstViewController.checkLogin(_:)))
         rightBarButton.image = buttonIcon

          self.tabBarController?.navigationItem.rightBarButtonItem = rightBarButton

我已经尝试了以下

let rightBarButton = UIBarButtonItem(title: "Person", style: UIBarButtonItem.Style.done, target: self, action: #selector(FirstViewController.checkLogin(_:)))
                    rightBarButton.kf.setImage(with: facebookProfileUrl, for: .normal, placeholder: nil, options: [.imageModifier(modifier)], progressBlock: nil, completionHandler: nil)
                    //rightBarButton.image = buttonIcon

                      self.tabBarController?.navigationItem.rightBarButtonItem = rightBarButton

但它会返回

使用未解析的标识符“修饰符”

【问题讨论】：

rightBarButton.kf.setImage(with: url)
@iOSArchitect.com 我已经设置了 let facebookProfileUrl = "graph.facebook.com/(fbID)/picture?type=large"
检查我的答案
@iOSArchitect.com 对您的回答发表的评论似乎是 .kf 的问题

【解决方案1】：

创建一个自定义按钮并将其设置为 UIBarButton 并将图像设置为按钮。

  let button = UIButton()
  button.frame = CGRect(x: 0, y: 0, width: 51, height: 31) //set the frame
  let modifier = AnyImageModifier { return $0.withRenderingMode(.alwaysOriginal) }
  button.kf.setImage(with: url, for: .normal, placeholder: nil, options: [.imageModifier(modifier)], progressBlock: nil, completionHandler: nil)
  button.addTarget(self, action: Selector("yourActionFunc"), for: .touchUpInside)

  let barButton = UIBarButtonItem()
  barButton.customView = button
  self.navigationItem.rightBarButtonItem = barButton

然后我得到“UIBarButtonItem”类型的值没有成员“kf”
