ios – 将UIViewController添加到UIScrollView swift 3

概述我正在研究ScrollView.目前我在ScrollView中有两个图像,我想在ScrollView中添加至少一个新的UIViewController. 那是我的代码： self.scrollView.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.scrollView.frame.height) 我正在研究ScrollVIEw.目前我在ScrollVIEw中有两个图像,我想在ScrollVIEw中添加至少一个新的UIVIEwController.

那是我的代码：

self.scrollVIEw.frame = CGRect(x: 0,y: 0,wIDth: self.vIEw.frame.wIDth,height: self.scrollVIEw.frame.height)    let scrollvIEwHeight = self.scrollVIEw.frame.height    let scrollvIEwWIDth = self.scrollVIEw.frame.wIDth    var imgOne = UIImageVIEw(frame: CGRect(x: 0,wIDth: scrollvIEwWIDth,height: scrollvIEwHeight))    var imgTwo = UIImageVIEw(frame: CGRect(x: scrollvIEwWIDth,height: scrollvIEwHeight))    imgOne.image = UIImage(named: "prevIEw1")    imgTwo.image = UIImage(named: "prevIEw2")    self.scrollVIEw.addSubvIEw(imgOne)    self.scrollVIEw.addSubvIEw(imgTwo)    self.scrollVIEw.contentSize = CGSize(wIDth: self.scrollVIEw.frame.wIDth * 2,height: self.scrollVIEw.frame.height)    self.scrollVIEw.isPagingEnabled = true

设计：

The first one is the root ViewController,where the ScrollView is and the second one I want to add in the ScrollView

解决方法 试试看,看看：

self.scrollVIEw.frame = CGRect( <set frame> )var imgOne = UIImageVIEw(frame: CGRect( <set frame> ))var imgTwo = UIImageVIEw(frame: CGRect( <set frame> ))var vcVIEw = UIVIEw(frame: CGRect( <set frame> ))addChildVC(vcVIEw: vcVIEw)imgOne.image = UIImage(named: "prevIEw1")imgTwo.image = UIImage(named: "prevIEw2")self.scrollVIEw.addSubvIEw(imgOne)self.scrollVIEw.addSubvIEw(imgTwo)self.scrollVIEw.addSubvIEw(vcVIEw)self.scrollVIEw.contentSize = CGSize( <set content size> )self.scrollVIEw.isPagingEnabled = true

添加子视图控制器

func addChildVC(vcVIEw: UIVIEw){let testVC = self.storyboard?.instantiateVIEwControllerWithIDentifIEr("testIDentifIEr") as! TestVIEwController    testVC.vIEw.frame = vcVIEw.bounds    vcVIEw.addSubvIEw(testVC.vIEw)    self.addChildVIEwController(testVC)    testVC.dIDMovetoParentVIEwController(self)}
