推荐答案

我更新了快速修复的方法在展示CNContactPickerViewController之前，您应该设置UISearchBar的背景颜色

I updated the way to fix in swiftBefore you present CNContactPickerViewController, you should set background color of UISearchBar

            UISearchBar.appearance().backgroundColor = UIColor.white
        let cancelButtonAttributes = [NSForegroundColorAttributeName: ColorConstant.baseColorGray]
        UIBarButtonItem.appearance(whenContainedInInstancesOf:
         [UISearchBar.self]).setTitleTextAttributes(cancelButtonAttributes, for: .normal)
