I want customize page control like a image.
I've already search that, but there are only deal scale.
I want change width, height, spacing.
How can I do that?
I tried this
class DefaultPageControl: UIPageControl {
override var currentPage: Int {
didSet {
updateDots()
}
}
func updateDots() {
let currentDot = subviews[currentPage]
subviews.forEach {
$0.frame.size = ($0 == currentDot) ? CGSize(width: 16, height: 4) : CGSize(width: 8, height: 4)
$0.layer.cornerRadius = 2
}
}
}
But how to change distance??
#oddK Can you try with this below answer. It's my assumption.
class DefaultPageControl: UIPageControl {
override var currentPage: Int {
didSet {
updateDots()
}
}
func updateDots() {
let currentDot = subviews[currentPage]
let spacing = 5.0
subviews.forEach {
$0.frame = ($0 == currentDot) ? CGRect(x: 0, y: 0, width: 16, height: 4) : CGRect(x: spacing, y: 0, width: 8, height: 4)
//$0.frame.size = ($0 == currentDot) ? CGSize(width: 16, height: 4) : CGSize(width: 8, height: 4)
$0.layer.cornerRadius = 2
}
}
}
The default UIPageControll is not flexible.
class ExtendedpageControll: UIView{
var numberOfPage: Int
var currentpage : Int = 0{didSet{reloadView()}}
var currentIndicatorColor: UIColor = .black
var indicatorColor: UIColor = UIColor(white: 0.9, alpha: 1)
var circleIndicator: Bool = false
private var dotView = [UIView]()
private let spacing: CGFloat = 6
private lazy var extraWidth: CGFloat = circleIndicator ? 6 : 4
init(numberOfPages: Int,currentPage: Int,isCircular: Bool){
self.numberOfPage = numberOfPages
self.currentpage = currentPage
self.circleIndicator = isCircular
super.init(frame: .zero)
configView()
}
required init?(coder: NSCoder) {fatalError("not implemented")}
private func configView(){
backgroundColor = .clear
(0..<numberOfPage).forEach { _ in
let view = UIView()
addSubview(view)
dotView.append(view)
}
}
private func reloadView(){
dotView.forEach{$0.backgroundColor = indicatorColor}
dotView[currentpage].backgroundColor = currentIndicatorColor
UIView.animate(withDuration: 0.2) {
self.dotView[self.currentpage].frame.origin.x = self.dotView[self.currentpage].frame.origin.x - self.extraWidth
self.dotView[self.currentpage].frame.size.width = self.dotView[self.currentpage].frame.size.width + (self.extraWidth * 2)
}
}
override func layoutSubviews() {
super.layoutSubviews()
for (i,view) in dotView.enumerated(){
view.clipsToBounds = true
view.layer.cornerRadius = bounds.height / 2
let width: CGFloat = circleIndicator ? self.bounds.height : CGFloat(self.bounds.width / CGFloat(self.numberOfPage) - self.spacing) - self.extraWidth
UIView.animate(withDuration: 0.2) {
view.frame = CGRect(x: ((self.bounds.width / CGFloat(self.numberOfPage)) * CGFloat(i)) + self.spacing, y: 0, width: width , height: self.bounds.height)
}
}
reloadView()
}
}
Usage: If you want to link ExtendedpageControll to a View Such as CollectionView Just Do like this: (item is your Datamodel)
class SampleViewController: UIViewController{
let colectionView = UICollectionView()
lazy var pageControll: ExtendedpageControll = {
let pc = ExtendedpageControll(numberOfPages: items.count, currentPage: 0,isCircular: true)
pc.currentIndicatorColor = .black
return pc
}()
func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
if pageControll.currentpage == indexPath.row {
guard let visible = self.collectionView.visibleCells.first else { return }
guard let index = self.collectionView.indexPath(for: visible)?.row else { return }
pageControll.currentpage = index
}
}
}
inside init, you can set the shape of the indicator to be circular or extended via isCircular.
I am trying to build a carousel on my app based on this project, https://github.com/nicklockwood/iCarousel, only I am writing it in swift. I have it working correctly, where you can scroll through and tap on the item at index correctly here:
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
let tempView = UIView(frame: CGRect(x: 0, y: 130, width: 295, height: 300))
let object = self.imageFilesArray.object(at: index) as! PFObject
let imageView = UIImageView()
imageView.frame = CGRect(x: 0, y: 0 , width: 295, height: 295)
imageView.layer.cornerRadius = 15
imageView.layer.masksToBounds = true
let imageFile = object.object(forKey: "Image") as! PFFile
imageFile.getDataInBackground{
(data, error) -> Void in
if error == nil {
}
imageView.image = UIImage(data: data!)
tempView.addSubview(imageView)
}
return tempView
}
func carousel(_ carousel: iCarousel, didSelectItemAt index: Int) {
let cell = carouselView.itemView(at: index)
let object = self.imageFilesArray[index] as! PFObject
if cell?.tag == 0 {
print("open cell")
let moveImg = CGAffineTransform(translationX: 0, y: -100)
UIView.animate(withDuration: 0.4, delay: 0.1, options: [], animations: {
//cell.imageView.transform = moveImg
}, completion: nil)
cell?.tag = 1
} else if cell?.tag == 1 {
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "EventDetailViewController") as! EventDetailViewController
self.present(nextViewController, animated:false, completion:nil)
}
However, what I am trying to do is when I tap the item at index, the imageView transitions on the screen. My issue is that I cannot access that particular cells imageView in order to move it. Does anyone know what I need to change?
You could give your imageView a tag like this:
let imageView = UIImageView()
imageView.frame = CGRect(x: 0, y: 0 , width: 295, height: 295)
imageView.layer.cornerRadius = 15
imageView.layer.masksToBounds = true
imageView.tag = 2
Then you can retrieve the imageView from the cell like this:
if let imageView = cell.viewWithTag(2) as? UIImageView {
imageView.transform = moveImg
}
OR
You could filter through the subviews of the cell and find the first subview that can be cast to a UIImageView. Although this isn't very robust, consider creating a Class and XIB for this cell.
cell.subviews.flatMap { $0 as? UIImageView }.first?.transform = moveImg
I am having an issue with memory usage. Whenever I scroll or reload the data the memory usage keeps going up and never goes down. I have a feeling that for some reason the cells are not releasing any of the items displayed.
Any help would be greatly appreciated. I am quite sure I am doing something wrong, but I can't seem to find what.
Thank you in advance

And in viewDidLoad()
self.tblView.tableFooterView = self.createFooterView();
Here is a Storyboard example of iCarousel implementation in Swift: https://github.com/nicklockwood/iCarousel/tree/master/Examples/Swift%20Example
Particularly this page:
https://github.com/nicklockwood/iCarousel/blob/master/Examples/Swift%20Example/SwiftExample/ViewController.swift
Can somebody guide me how to implement it programmatically (without Storyboards)?
swift 3
private let HEIGHT_CAROUSEL: CGFloat = 100
private func initiCarousel() {
let carousel = iCarousel(frame: CGRect(x: 0, y: view.frame.height - HEIGHT_CAROUSEL, width: view.frame.width, height: HEIGHT_CAROUSEL))
carousel.delegate = self
carousel.dataSource = self
view.addSubview(carousel)
}
// MARK: - iCarouselDelegate
extension YourNameViewController: iCarouselDataSource, iCarouselDelegate {
func numberOfItems(in carousel: iCarousel) -> Int {
return arrr.count ?? 0
}
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
var itemView: UIImageView
itemView = UIImageView(frame: CGRect(x: 0, y: 0, width: HEIGHT_CAROUSEL, height: HEIGHT_CAROUSEL))
itemView.contentMode = .scaleAspectFill
if let image = url {
itemView.setImageWithIndicator(imageUrl: image)
}
return itemView
}
func carousel(_ carousel: iCarousel, valueFor option: iCarouselOption, withDefault value: CGFloat) -> CGFloat {
if (option == .spacing) {
return value * 1.1
}
return value
}
}
Use following code to implement iCarousel programmatically using swift:
override func viewDidLoad()
{
super.viewDidLoad()
carousel = iCarousel(frame: CGRectMake(0, 0, 200, 200))
carousel.center = view.center
carousel.dataSource = self
carousel.delegate = self
}
