我想在导航栏扩展中同时显示两个菜单,并在滚动时隐藏除扩展名之外的导航栏。
我能够通过PageMenu“PageMenu”获取菜单并隐藏导航栏AMScrollingNavbar
但我现在面临的问题是导航栏隐藏但视图不会向上移动导航栏
func loadControllers(){
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let topViewController = storyboard.instantiateViewControllerWithIdentifier("TopNewsController") as!
TopNewsController
topViewController.title = "TOP"
controllerArray.append(topViewController)
let briefViewController = storyboard.instantiateViewControllerWithIdentifier("BriefViewController") as!
BriefViewController
briefViewController.title = "BRIEFS"
controllerArray.append(briefViewController)
let videoViewController = storyboard.instantiateViewControllerWithIdentifier("VediosViewController") as!
VediosViewController
videoViewController.title = "VIDEOS"
controllerArray.append(videoViewController)
// Customize menu
parameters = [
.ScrollMenuBackgroundColor(UIColor.navigationBarColor()),
.ViewBackgroundColor(UIColor(red: 20.0/255.0, green: 20.0/255.0, blue: 20.0/255.0, alpha: 1.0)),
.SelectionIndicatorColor(UIColor.whiteColor()),
.BottomMenuHairlineColor(UIColor(red: 70.0/255.0, green: 70.0/255.0, blue: 80.0/255.0, alpha: 1.0)),
.MenuItemFont(UIFont(name: "HelveticaNeue-Bold", size: 14.0)!),
.MenuHeight(expressTribuneUtilities.convertIphone6ToIphone5(48)),
.MenuItemWidth(90.0),
.CenterMenuItems(true)
]
AppDelegate.getInstatnce().nav = self.navigationController as! ScrollingNavigationController
AppDelegate.getInstatnce().nav.scrollingNavbarDelegate = self
// Initialize scroll menu
pageMenu = CAPSPageMenu(viewControllers: controllerArray, frame: CGRectMake(0.0, 64.0, self.view.frame.width, self.view.frame.height), pageMenuOptions: parameters)
self.view.addSubview(pageMenu!.view)
}
从菜单中添加的类中调用Scroll方法
AppDelegate.getInstatnce().nav.followScrollView(tableMainView, delay: 0.5)
答案 0 :(得分:2)
let navController = AppDelegate.getInstatnce().window?.rootViewController as! ScrollingNavigationController
navController.scrollingNavbarDelegate = self
将这两行改为像这样它不会工作,因为你正在为其他实例而不是你的导航设置委托。
