scrollview加载多个自定义UI界面以实现滚动效果

创建多个ViewController与多个Storyboard，这里分别新建了三个

在每个storyboard中选中第一个顶级view

在右侧的Custom Class中为其绑定Controller，并设置Storyboard ID

在主界面中创建一个ScrollView，并设值其宽高与可滑动的距离

scrollView=UIScrollView(frame: CGRectMake(CGFloat(0), CGFloat(0), screenWidth, screenHeight))

scrollView.contentSize=CGSizeMake(CGFloat(3)*screenWidth, screenHeight-offsetY)

scrollView.pagingEnabled=true

scrollView.delegate=self

寻找到各个storyboard与其绑定的控制器与view

var oneSB=UIStoryboard(name: "One", bundle: nil)

var twoSB=UIStoryboard(name: "Two", bundle: nil)

var threeSB=UIStoryboard(name: "Third", bundle: nil)

var one=oneSB.instantiateViewControllerWithIdentifier("one") as OneViewController

var two=twoSB.instantiateViewControllerWithIdentifier("two") as TwoViewController

var three=threeSB.instantiateViewControllerWithIdentifier("three") as ThirdViewController

one.view.frame=CGRectMake(0, 0, screenWidth, screenHeight)

two.view.frame=CGRectMake(screenWidth, 0, screenWidth, screenHeight)

three.view.frame=CGRectMake(screenWidth*2, 0, screenWidth, screenHeight)

scrollView.addSubview(one.view)

scrollView.addSubview(two.view)

scrollView.addSubview(three.view)

若scrollView为storyboard中绑定的控件，这样已经完成，若是在代码中创建的scrollView，则需要添加一句

view.addSubview(scrollView)
