導航欄自定義圖像視圖問題11

Question

我設置一個正常的圖像視圖作爲我的導航欄項目自定義視圖，但是這是它的發生：

let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 34, height: 34)) 
imageView.kf.setImage(with: user.profilePictureURL) 
if user.profilePictureURL == nil { 
    imageView.image = #imageLiteral(resourceName: "ProfilePlaceholderSuit") 
} 
imageView.backgroundColor = .white 
imageView.layer.masksToBounds = true 
imageView.layer.cornerRadius = 17 
imageView.layer.borderWidth = 1 
imageView.layer.borderColor = UIColor.white.cgColor 
imageView.isUserInteractionEnabled = true 
imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTap))) 
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: imageView) 
print("ok, so the image view frame is", imageView.frame) // 0, 0, 34, 34 

Answer 1

這類型所面臨的諸多開發商由於iOS中11 UIBarButtonItem問題，使用自動佈局而不是幀。

所以你只是想設置右上barButton項目然後please check my answer.配置文件圖像。

其他明智的，你可以在你的代碼像下面

let widthConstraint = imageView.widthAnchor.constraint(equalToConstant: 34) 
    let heightConstraint = imageView.heightAnchor.constraint(equalToConstant: 34) 
    heightConstraint.isActive = true 
    widthConstraint.isActive = true 

Answer 2

這是Kingfisher框架存在問題。我已經切換到SDWebImage並且它工作正常（有時）。

編輯：

這個工作

let imageView = UIImageView() 
imageView.translatesAutoresizingMaskIntoConstraints = false 
imageView.heightAnchor.constraint(equalToConstant: 34).isActive = true 
imageView.widthAnchor.constraint(equalToConstant: 34).isActive = true
