I want to use CUPS in iOS for printing and it is mentioned at many places that we can use cups for printing in ios .But when i import library cups/cups.h ,xcode is giving error "cups/cups.h not found". code i am using in a objective c file : import <cups/cups.h> cups_dest_t *dest; int num_options; cups_option_t *options; int job_id; /* Print a single file */ job_id = cupsPrintFile(dest->name, "/usr/share/cups/data/testprint.ps", "Test Print", num_options, options); Do i need to intall some driver or any library to make it work ? or is it the case that CUPS is not available for iOS?

when i am adding new view to replace viewcontroller's view like this : let viewcontroller: UIViewController! let rootview:UIView! viewcontroller = UIViewController () rootview = UIView (frame:viewcontroller.view.bounds) viewcontroller.view = rootview // Adding a button let button = UIButton(type: .system) button.setTitle("Tap Me", for: .normal) button.titleLabel?.font = UIFont.systemFont(ofSize: 18) button.addTarget(self, action: #selector(buttonTapped), for:.allEvents) viewcontroller.view.addSubview(button) For ios(iPhone/ipad) , i am able to get button click event . But in case of tvOS , i am not getting button click event. But in case of tvOS if use the default view of viewcontroller like this , i am getting button click events and things works fine: let viewcontroller: UIViewController! viewcontroller = UIViewController () // Adding a button let button = UIButton(type: .system) button.setTitle("Tap Me", for: .normal) button.titleLabel?.font = UIFont.systemFont(ofSize: 18) button.addTarget(self, action: #selector(buttonTapped), for:.allEvents) viewcontroller.view.addSubview(button) Is this some bug for tvOS or for tvOS this suppose to happen this way ?

I want to use uitableview in tvos to show list of string data but compiler is throughing following errors in generated header: "No type or protocol named 'UITableViewDataSource'" And "Attempting to use the forward class 'UITableView' as superclass of 'TWOSSelectionTableTVOS'" Even though this code is working is ios . My code structure is as follow : SelectionTable.swift: import UIKit class TWOSSelectionTableTVOS : UITableView { private var vDataSrc:[String]! func SetDataSrc (_ pDataSrc:[String]) { self.vDataSrc = pDataSrc } func UpdateDataSrc (_ pStringList:[String]) { self.vDataSrc += pStringList } func GetDataSrc () -> [String] { return self.vDataSrc } } PaintUI.swift : import UIKit @objc class PaintUI: NSObject,UITableViewDelegate, UITableViewDataSource { static let uShared = PaintUI () @objc static func updateUIMessage() { DispatchQueue.main.async { ExecuteInlineSelectionTable () } } func tableView (_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 5 } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell (withIdentifier: "cell", for: indexPath) cell.textLabel?.text = "hello" return cell } func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { let viewcontroller: TWIOSViewController! viewcontroller = StaticContext.sViewController } public static func ExecuteInlineSelectionTable () { let selectiontable:TWOSSelectionTableTVOS! selectiontable = TWOSSelectionTableTVOS () selectiontable.register (UITableViewCell.self, forCellReuseIdentifier: "cell") selectiontable.dataSource = uShared selectiontable.delegate = uShared selectiontable.isScrollEnabled = true // TODO : will add selection table in view heriearchy but currently getting // compilation error } } And finally calling PaintUI.updateUIMessage () , it is throughing above errors for tvOS only but in case of ios code is working fine.
