I would like to delete this junction (The line between the navigation bar and the ImageView Orange):

Is there someone who knows how to do?

Answer 1

In my case, I implemented the following code.

override func viewDidLoad() {
    super.viewDidLoad()

    if self.navigationController != nil {
        hideBorder(self.navigationController!.navigationBar)
    }
}

func hideBorder(view: UIView) -> Bool {
    if view.isKindOfClass(UIImageView.classForCoder()) && view.frame.size.height <= 1 {
        view.hidden = true
        return true
    }

    for sub in view.subviews {
        if hideBorder(sub as! UIView) {
            return true
        }
    }
    return false
}
