简单记录,为后续方便查找,仅有代码片段
可以放在ViewController的基类中
if let bar = self.navigationController?.navigationBar {
bar.backgroundColor = .themeColor
bar.tintColor = .white
var attrs = bar.titleTextAttributes
if attrs == nil {
attrs = [NSAttributedStringKey:Any]()
}
attrs?[NSAttributedStringKey.foregroundColor] = UIColor.white
bar.titleTextAttributes = attrs
}
