NavigationController中的PageViewController子句在ios中滚动问题的ViewController

我的DetailsVIEwController包含scrollvIEw和detailsvIEwController数组,不同的数据被传递给pagevIEwcontroller.

问题只是第一个vIEwvIEw控件的pagevIEw控件显示在navigartionbar下,其scrollvIEw正在工作.

但是休息是在导航控制器下推动的,并且scrollvIEw不起作用.

1st image：First Details视图控制器正常工作

第二张图像：当我滑动时,数据集中的下一个DetailsVIEwController.这里的内容在导航栏下滚动,滚动视图无效

经过进一步研究后,我发现除了first之外,其余detailsvIEwcontroller的navigationcontroller属性为nil.

解决方法 这曾经发生在我身上,所以我当时做了什么,我添加了一个普通的VIEwController并使其成为NavigationVIEwController的根控制器.现在,我在这个VIEwController中添加了PageVIEwController.然后一切都很好.简而言之,尽管使NavigationController成为父控制器,但将导航控制器的根VIEwController作为PageVIEwController的父级.

我在vIEwController.swift(导航控制器的根视图控制器)中创建了pageVIEwController实例,VIEwController.swift看起来像：

import UIKitclass VIEwController: UIVIEwController,UIPageVIEwControllerDataSource,UIPageVIEwControllerDelegate {    var pageVIEwController:UIPageVIEwController?    var presentIndex = 0    overrIDe func vIEwDIDLoad() {        super.vIEwDIDLoad()        self.pageVIEwController = UIPageVIEwController.init(TransitionStyle: UIPageVIEwControllerTransitionStyle.Scroll,navigationorIEntation: UIPageVIEwControllerNavigationorIEntation.Horizontal,options: nil)        self.pageVIEwController!.dataSource=self        let initialVIEwController:DetailVIEwController = self.giverequiredVIEwController(1)        let vIEwControllerArray:NSArray = [initialVIEwController]        self.pageVIEwController?.setVIEwControllers(vIEwControllerArray as! [DetailVIEwController],direction: UIPageVIEwControllerNavigationDirection.Forward,completion: nil)        self.addChildVIEwController(self.pageVIEwController!)        self.vIEw.addSubvIEw((self.pageVIEwController?.vIEw)!)        self.pageVIEwController?.dIDMovetoParentVIEwController(self)        self.vIEw.backgroundcolor=UIcolor.blackcolor()        self.navigationController?.navigationbar.barTintcolor=UIcolor.redcolor()        // Do any additional setup after loading the vIEw,typically from a nib.    }    overrIDe func vIEwWillLayoutSubvIEws() {        let frame = CGRectMake(0,64,self.vIEw.frame.wIDth,self.vIEw.frame.height-40)        self.pageVIEwController?.vIEw.frame = frame    }    func pageVIEwController(pageVIEwController: UIPageVIEwController,vIEwControllerBeforeVIEwController vIEwController: UIVIEwController) -> UIVIEwController? {        presentIndex = (vIEwController as! DetailVIEwController).index!        if presentIndex==0{            return nil        }       return self.giverequiredVIEwController(presentIndex-1)    }    func giverequiredVIEwController(index:NSInteger) -> DetailVIEwController {        let detailVIEwController = DetailVIEwController(nibname: "DetailVIEwController",bundle: nil)        detailVIEwController.index = index        return detailVIEwController    }    func pageVIEwController(pageVIEwController: UIPageVIEwController,vIEwControllerAfterVIEwController vIEwController: UIVIEwController) -> UIVIEwController? {        presentIndex = (vIEwController as! DetailVIEwController).index!        if presentIndex==1{            return nil        }        return self.giverequiredVIEwController(presentIndex+1)    }    overrIDe func dIDReceiveMemoryWarning() {        super.dIDReceiveMemoryWarning()        // dispose of any resources that can be recreated.    }}

我提供了DetailVIEwController的索引,这个索引基本上会告诉我正在呈现哪个页面,我会相应地调整我的视图.现在我已经更改了视图更改的背景颜色.
目前只有两页,你可以拥有尽可能多的页面.

DetailVIEwController.swift代码是这样的,

import UIKitclass DetailVIEwController: UIVIEwController {    var index:NSInteger?    overrIDe func vIEwDIDLoad() {        super.vIEwDIDLoad()        if index==0{            self.vIEw.backgroundcolor=UIcolor.bluecolor()        }else{            self.vIEw.backgroundcolor = UIcolor.graycolor()        }        // Do any additional setup after loading the vIEw.    }    overrIDe func dIDReceiveMemoryWarning() {        super.dIDReceiveMemoryWarning()        // dispose of any resources that can be recreated.    }}
