|

|
|
// 但这样有个风险，因为 QMUIConfiguration 配置表里都是用 appearance 的方式去设置 standardAppearance，所以如果在 UINavigationBar 实例被添加到 window 之前修改过旧版任意一个样式接口，就会导致一个新的 UINavigationBarAppearance 对象被设置给 standardAppearance 属性，这样系统就会认为你这个 UINavigationBar 实例自定义了 standardAppearance，那么当它被 moveToWindow 时就不会自动应用 appearance 的值了，因此需要保证在添加到 window 前不要自行修改属性
