所以我尝试了一些测试应用程序，我很高兴地说你可以在 UIScrollviews 中拥有 UIScrollviews。
我能够让它完美运行。下面是我的代码。
override func viewDidLoad() {
super.viewDidLoad()
self.superView.delegate = self
// Do any additional setup after loading the view, typically from a nib.
var subImages1 = ["IMG_0004.JPG","IMG_0005.JPG","IMG_0008.JPG"]
var subImages2 = ["IMG_0009.JPG","IMG_0010.JPG","IMG_0011.JPG"]
var subImages3 = ["IMG_0013.JPG","IMG_0017.JPG","IMG_0018.JPG"]
self.images.append(subImages1)
self.images.append(subImages2)
self.images.append(subImages3)
self.superView.frame = self.view.frame
self.superView.contentSize = CGSizeMake(self.view.frame.width*3, self.view.frame.height)
self.superView.contentOffset = CGPoint(x:self.view.frame.width,y:0)
self.superView.pagingEnabled = true
self.view.addSubview(self.superView)
//layout the UIVeiws into the master ScrollView
for i in 0...2{
var offset = self.view.frame.width * CGFloat(i)
var pView = UIView()
pView.frame = CGRectMake(offset, 0, self.view.frame.width, self.view.frame.height)
pView.backgroundColor = colours[i]
self.superView.addSubview(pView)
self.profileViews.append(pView)
}
// Add sub Scroll views and images to the Views.
for (index, view) in enumerate(self.profileViews){
var scrollView = UIScrollView()
scrollView.delegate = self
scrollView.frame = CGRectMake(10, 10, self.view.frame.width-20, self.view.frame.height-20)
scrollView.pagingEnabled = true
scrollView.contentSize = CGSizeMake(scrollView.frame.width, scrollView.frame.height * CGFloat(images[index].count))
for (index2, image) in enumerate(images[index]){
var subImage = UIImageView()
subImage.frame = CGRectMake(0, scrollView.frame.height * CGFloat(index2), scrollView.frame.width, scrollView.frame.height)
subImage.contentMode = UIViewContentMode.ScaleAspectFit
subImage.image = UIImage(named: image as! String)
scrollView.addSubview(subImage)
}
view.addSubview(scrollView)
self.scrollViews.append(scrollView)
}
}
//Use the did end decelerating as it executes the code once the scoll has finished moving.
func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
if(scrollView == self.superView){
var contentOffset = scrollView.contentOffset
var pageWidth = self.superView.frame.width
var fractionalPage:Double = Double(self.superView.contentOffset.x / pageWidth)
var page = lround(fractionalPage)
// In this example I take the last UIView from the stack and move it to the first.
// I would do the same in the real app but update the contents of the view after
if(page == 0){
var tempView = self.profileViews[2]
self.profileViews[2].removeFromSuperview()
self.profileViews.removeAtIndex(2)
for view in self.profileViews{
view.frame = CGRectMake(view.frame.minX + self.view.frame.width, 0, view.frame.width, view.frame.height)
println(view.frame)
}
tempView.frame = CGRectMake(0, 0, tempView.frame.width, tempView.frame.height)
self.profileViews.insert(tempView, atIndex: 0)
self.superView.addSubview(tempView)
var newOffset = contentOffset.x + pageWidth
self.superView.contentOffset = CGPoint(x: newOffset, y: 0)
}
// Take the first view and move it to the last.
if(page == 2){
var tempView = self.profileViews[0]
self.profileViews[0].removeFromSuperview()
self.profileViews.removeAtIndex(0)
for view in self.profileViews{
view.frame = CGRectMake(view.frame.minX - self.view.frame.width, 0, view.frame.width, view.frame.height)
println(view.frame)
}
tempView.frame = CGRectMake(tempView.frame.width*2, 0, tempView.frame.width, tempView.frame.height)
self.profileViews.append(tempView)
self.superView.addSubview(tempView)
var newOffset = contentOffset.x - pageWidth
self.superView.contentOffset = CGPoint(x: newOffset, y: 0)
}
}
}
