您可以通过以下方式添加其他偏移量:
if #available(iOS 11.0, *) {
let navigationBarAppearance = UINavigationBar.appearance()
let style = NSMutableParagraphStyle()
style.alignment = .justified
style.firstLineHeadIndent = 18
navigationBarAppearance.largeTitleTextAttributes = [NSAttributedStringKey.paragraphStyle: style]
}

我刚刚在最新版本的iOS 12中发现,如果您仅修改layoutMargins
的{{1}}属性,就会影响大标题。
UINavigationBar
我尝试了此处提到的有关使用自定义let navigationBar = navigationController.navigationBar
navigationBar.layoutMargins.left = 36
navigationBar.layoutMargins.right = 36
的解决方案。确实确实可以,但是因为它延伸了由大标题组成的NSMutableParagraphStyle
视图,所以当您向下滑动时,在文本略微增长的地方播放的细微动画会变得相当失真。

你做不到。您需要编写自己的NavigationController,方法是为其创建UINavigationController。

你必须继承UINavigationBar,然后覆盖draw方法,并在里面进行更改。看看我的工作示例,然后根据需要调整偏移/样式:
override func draw(_ rect: CGRect) {
super.draw(rect)
self.backgroundColor = UIColor.white
let largeView = "_UINavigationBarLargeTitleView"
let labelcolor = UIColor(red: 36.0/255.0, green: 38.0/255.0, blue: 47.0/255.0, alpha: 1.0)
for view in self.subviews {
if largeView.contains(String(describing: type(of: view))) {
for v in view.subviews {
if String(describing: type(of: v)) == "UILabel" {
var titleLabel = v as! UILabel
var labelRect = titleLabel.frame
let labelInsets = UIEdgeInsets(top: 10, left: 13, bottom: 0, right: 0)
let attrText = NSMutableAttributedString(string: "Jobs", attributes: [NSAttributedStringKey.font: UIFont(name: "SFProDisplay-Heavy", size: 30)!, NSAttributedStringKey.foregroundColor: labelcolor])
labelRect.origin.y += 20
let newLabel = UILabel(frame: labelRect)
newLabel.attributedText = attrText
titleLabel.text = ""
if labelRect.origin.y > 0 {
titleLabel = newLabel
titleLabel.drawText(in: UIEdgeInsetsInsetRect(labelRect, labelInsets))
}
}
}
}
}
}
