}
//包装一个导航控制器
let nav = UINavigationController.init(rootViewController: childController)
//设置导航栏的背景颜色
nav.navigationBar.barTintColor = UIColor.lightGray
//标题颜色
let dic = [NSAttributedString.Key.foregroundColor : UIColor.orange,NSAttributedString.Key.font : UIFont.boldSystemFont(ofSize: 18)]
nav.navigationBar.titleTextAttributes = dic
//item颜色
nav.navigationBar.tintColor = UIColor.gray
addChild(nav)
}
}
前边 if let name = Bundle.main.infoDictionary!["CFBundleExecutable"] as? String {
中的name就是这里设置的
如果再加上服务器网络请求可以做成动态的实现apptabbar展示页等。但是这些页面必须提前做好放到项目里面
我在本地添加了一个.json文件
