I have a slight problem, my menu which I created doesn't seem to want to scroll till the bottom.
I have created it programmaitacally
var dataSource = [String]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.register(CellClass.self, forCellReuseIdentifier: "Cell")
}
func addTransparentView(frames: CGRect) {
let window = UIApplication.shared.keyWindow
transparentView.frame = window?.frame ?? self.view.frame
self.view.addSubview(transparentView)
tableView.frame = CGRect(x: frames.origin.x, y: frames.origin.y + frames.height, width: frames.width, height: 50)
self.view.addSubview(tableView)
tableView.layer.cornerRadius = 4
transparentView.backgroundColor = UIColor.black.withAlphaComponent(0.9)
tableView.reloadData()
let tapgesture = UITapGestureRecognizer(target: self, action: #selector(removeTransparentView))
transparentView.addGestureRecognizer(tapgesture)
transparentView.alpha = 0
UIView.animate(withDuration: 0.4, delay: 0.0, usingSpringWithDamping: 2.0, initialSpringVelocity: 2.0, options: .curveEaseInOut,animations: {
self.transparentView.alpha = 0.5
self.tableView.frame = CGRect(x: frames.origin.x, y: frames.origin.y + frames.height + 1, width: frames.width, height: CGFloat(self.dataSource.count * 50))
}, completion: nil)
}
#objc func removeTransparentView() {
let frames = selectedButton.frame
UIView.animate(withDuration: 0.4, delay: 0.0, usingSpringWithDamping: 1.0, initialSpringVelocity: 1.0, options: .curveEaseInOut,animations: {
self.transparentView.alpha = 0
self.tableView.frame = CGRect(x: frames.origin.x, y: frames.origin.y + frames.height, width: frames.width, height: 0)
}, completion: nil)
}
#IBAction func onClickSelectProperty(_ sender: Any) {
dataSource = ["Apartment A3","Apartment A4","Apartment A5","Apartment A6","Apartment A8","Apartment A9","Apartment A12","Apartment E1","Sectional Title 50A","Sectional Title 65A","Free Standing 70A","Free Standing 70A Core","Free Standing 85A","Free Standing 100A"]
selectedButton = btnSelectPropert
addTransparentView(frames: btnSelectPropert.frame)
}
I would like to scroll till the bottom, somehow it doesn't allow me
how the table/menu looks like

I'm trying to execute a function after an animation. This will need to be a different function each time so I introduced an argument as a CGFunction. What's weird though is that when I'm running this code I actually get "yes" printed to console which means that it's working fine. But the program crashes a few seconds later, and what's even weirder is that "view running" actually never gets printed to console. If anybody could take a look and let me know what's causing this problem I'd really appreciate it. Thanks.

hi fellow developer I want to swipe between uiview with scrollView while changing the the index and small indicator move left and right. but is not responding while I try to swipe. this is my picture and my setup to scroll between uiview. can you tell me where I am missing?
let segmentedControl = UISegmentedControl()
let containerView = UIView()
let indicatorView = UIView()
let leftView = UIView()
let rightView = UIView()
let scrollView = UIScrollView()
var slides = [UIView]()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .systemBackground
slides.append(leftView)
slides.append(rightView)
segmentedControl.insertSegment(withTitle: "Harian", at: 0, animated: true)
segmentedControl.insertSegment(withTitle: "Mata Pelajaran", at: 1, animated: true)
segmentedControl.selectedSegmentIndex = 0
segmentedControl.addTarget(self, action: #selector(handleTap), for: .valueChanged)
setupSlideScrollView()
}
func setupSlideScrollView() {
view.addSubview(scrollView)
scrollView.isPagingEnabled = true
scrollView.translatesAutoresizingMaskIntoConstraints = false
for i in 0..<slides.count {
slides[i].frame = CGRect(x: view.frame.width * CGFloat(i), y: 0, width: view.frame.width, height: view.frame.height)
scrollView.addSubview(slides[i])
}
}
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let pageIndex = round(scrollView.contentOffset.x / view.frame.width)
segmentedControl.selectedSegmentIndex = Int(pageIndex)
}
#objc func handleTap(_ sender: UISegmentedControl) {
indicatorView.frame.origin.x = (segmentedControl.frame.width / CGFloat(segmentedControl.numberOfSegments)) * CGFloat(segmentedControl.selectedSegmentIndex)
UIView.animate(withDuration: 0.5, animations: {
self.view.layoutIfNeeded()
self.indicatorView.transform = CGAffineTransform(scaleX: 0.7, y: 1)
}) { (finish) in
UIView.animate(withDuration: 0.4, animations: {
self.indicatorView.transform = CGAffineTransform.identity
})
}
}
i am working on application where i am trying to call controllers with animations
second view controller with animations
like when i call second controller with segue
second controller come from right and first controller start moving to left
like android push pop animations
i make some code
class SegueFromRight: UIStoryboardSegue {
override func perform() {
let src = self.source
let dst = self.destination
src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)
dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width*2, y: 0)
//Double the X-Axis
UIView.animate(withDuration: 0.25, delay: 0.0, options: UIView.AnimationOptions.curveEaseInOut, animations: {
dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
}) { (finished) in
src.present(dst, animated: false, completion: nil)
}
}
}
but from this code new controller come from right i need to move current controller to move left too
if anyone can help
Try this code:
class CustomSegue: UIStoryboardSegue {
override func perform() {
let firstVCView: UIView = self.source.view
let secondVCView: UIView = self.destination.view
self.destination.modalPresentationStyle = .fullScreen
let screenWidth = UIScreen.main.bounds.size.width
let screenHeight = UIScreen.main.bounds.size.height
secondVCView.frame = CGRect(x: screenWidth, y: 0, width: screenWidth, height: screenHeight)
let window = UIApplication.shared.keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
UIView.animate(withDuration: 0.4, animations: { () -> Void in
firstVCView.frame = firstVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
secondVCView.frame = secondVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
}) { (Finished) -> Void in
self.source.present(self.destination as UIViewController,
animated: false,
completion: nil)
}
}
}
class CustomSegueUnwind: UIStoryboardSegue {
override func perform() {
let secondVCView: UIView = self.source.view
let firstVCView: UIView = self.destination.view
self.destination.modalPresentationStyle = .fullScreen
let screenWidth = UIScreen.main.bounds.size.width
let window = UIApplication.shared.keyWindow
window?.insertSubview(firstVCView, aboveSubview: secondVCView)
UIView.animate(withDuration: 0.4, animations: { () -> Void in
firstVCView.frame = firstVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
secondVCView.frame = secondVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
}) { (Finished) -> Void in
self.source.dismiss(animated: false, completion: nil)
}
}
}

I have managed to create, a dark overlay once clicked a search icon and have managed to add a table uiview on the dark overlay but now want to add a search bar within that table view. I cant seem to figure it out as my code seems different to everyone else's examples. I am new to swift so my code probably isn't the cleanest. can i ask if someone can show me how to do this as i am out of ideas. I have posted my code below can someone please show me where i'm going wrong.
Many thanks
class SearchLauncher: NSObject {
let blackView = UIView()
let tableView = UITableView()
#objc func showSearch() {
if let window = UIApplication.shared.keyWindow {
blackView.backgroundColor = UIColor(white: 0, alpha: 0.5)
blackView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleDismiss)))
window.addSubview(blackView)
window.addSubview(tableView)
let height: CGFloat = 600
let y = window.frame.height - height
tableView.frame = CGRect(x: 0, y: window.frame.height, width: window.frame.width, height: height)
blackView.frame = window.frame

How did you try to add a search controller?
I would do it by adding an UISearchController as a tableHeaderView of your table view. First make sure to add UISearchResultsUpdating protocol to your class.
class SearchLauncher: NSObject, UISearchResultsUpdating
Then add the search bar to your table view
let searchController = UISearchController(searchResultsController: nil)
searchController.searchBar.sizeToFit()
searchController.searchResultsUpdater = self
//you probably don't need this
//searchController.dimsBackgroundDuringPresentation = false
tableView.tableHeaderView = searchController.searchBar
And then, implement the updateSearchResults(for:_) delegate method
func updateSearchResults(for searchController: UISearchController) {
filteredTableData.removeAll(keepingCapacity: false)
//filter the table data by using searchController.searchBar.text!
//filteredTableData = ...
self.tableView.reloadData()
}
I have a slide-in menu that presents itself when I press the menu button in my navigation bar. Dismissing it can be accomplished by either tapping the background or the menu itself. Within this view I have several items, one of which is an user profile button. When I press this button, I want the menu to dismiss itself and then instantly open the user profile view controller. That's why I call handleDismiss() first and then set the view that needs to be opened
However, it keeps telling me that the view is not in the window hierarchy. I know what the problem is (view stack), but I somehow can't get it to work properly. How should I tackle this problem?
RootViewController -> HomeController (tabBar index 0) -> Slide-In Menu -> UserProfileController
Button to open the controller
profileCell.profileButton.addTarget(self, action: #selector(handleUserProfile(sender:)), for: .touchUpInside)
Functions
func handleDismiss() {
UIView.animate(withDuration: 0.5) {
self.blackView.alpha = 0
if let window = UIApplication.shared.keyWindow {
self.collectionView.frame = CGRect(x: 0, y: window.frame.height, width: self.collectionView.frame.width, height: self.collectionView.frame.height)
}
}
}
func handleUserProfile(sender: UIButton) {
handleDismiss()
let userProfileController = UserProfileController()
openProfileController(userProfileController)
}
func openProfileController(_ controller: UIViewController) {
present(controller, animated: false, completion: nil)
}
I fixed the problem by setting a reference to the rootViewController in my menu.
HomeController
let menuLauncher = MenuLauncher()
func tappedMenu(sender: UIButton) {
menuLauncher.showMenu(self)
}
MenuController
func MenuLauncher() {
self.m_ParentViewController = nil
}
func showMenu(_ parentViewController: UIViewController) {
self.m_ParentViewController = parentViewController
collectionView.dataSource = self
collectionView.delegate = self
collectionView.register(MenuLauncherImageCell.self, forCellWithReuseIdentifier: cellIdImage)
collectionView.register(MenuLauncherInfoCell.self, forCellWithReuseIdentifier: cellIdInfo)
if let window = UIApplication.shared.keyWindow {
blackView.backgroundColor = UIColor(white: 0, alpha: 0.5)
blackView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleDismiss)))
window.addSubview(blackView)
window.addSubview(collectionView)
collectionView.frame = CGRect(x: 0, y: window.frame.height, width: window.frame.width, height: 350)
blackView.frame = window.frame
blackView.alpha = 0
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
self.blackView.alpha = 1
self.collectionView.frame = CGRect(x: 0, y: window.frame.height - 350, width: self.collectionView.frame.width, height: self.collectionView.frame.height)
}, completion: nil)
}
}
func handleDismiss() {
UIView.animate(withDuration: 0.5) {
self.blackView.alpha = 0
if let window = UIApplication.shared.keyWindow {
self.collectionView.frame = CGRect(x: 0, y: window.frame.height, width: self.collectionView.frame.width, height: self.collectionView.frame.height)
}
}
}
func handleUserProfile(sender: UIButton) {
handleDismiss()
let userProfileController = UserProfileController()
self.m_ParentViewController?.present(userProfileController, animated: true, completion: nil)
}
