Trying to pass the variable from a text input on viewcontroller.swift to a second view page (view2). Having trouble with string() as an input. Here's what I have:
import Foundation
import AVFoundation
import UIKit
import AVKit
class View2 : UIViewController {
var PlayerViewController = AVPlayerViewController()
var PlayerView = AVPlayer()
override func viewDidLoad() {
super.viewDidLoad()
}
let fileURL = NSURL (fileURLWithPath: String())
PlayerView = AVPlayer (URL: srcURL)
PlayerViewController.player = PlayerView
self.presentViewController(PlayerViewController, animated: true){
self.PlayerViewController.player?.play()
}
}
Drag your TextView from storyboard to your View Controller swift file as an Outlet
and give it a name for example
#IBOutlet weak var texty: UITextField!
and then set a variable for example
var yourTexty: String!
and then you do
yourTexty = texty.text

I am trying to get the splash view ( back_button ) to remove itself once the webpage fully loads, I had done quite a bit of researching and they always point to the same code as an answer. However, mine will not get called. Can somebody advise what I am doing wrong?
import UIKit
import WebKit
class ViewController: UIViewController {
#IBOutlet weak var LoadingView: UIImageView!
var webView: WKWebView?
var bgImage: UIImageView?
var imageViewObject :UIImageView?
override func viewDidLoad() {
super.viewDidLoad()
//var imageViewObject :UIImageView
let screenSize: CGRect = UIScreen.main.bounds
imageViewObject = UIImageView(frame:CGRect(x:0,y: 0, width: screenSize.width, height: screenSize.height))
imageViewObject?.image = UIImage(named:"back_image")
webView?.navigationDelegate = self as? WKNavigationDelegate
self.view.addSubview(imageViewObject!)
let myURL = URL(string: "https://www.google.com")
let myRequest = URLRequest(url: myURL!)
_ = webView?.load(myRequest)
}
override func loadView() {
super.loadView()
//self.view.sendSubview(toBack: imageViewObject)
//self.view = self.LoadingView
self.webView = WKWebView()
self.view = self.webView
}
#IBAction func BackButton(_ sender: Any) {
if(webView?.canGoBack)!
{
webView?.goBack();
}
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
print("TEST")
imageViewObject?.removeFromSuperview()
}
func webViewDidFinishLoad(webView: WKWebView) {
imageViewObject?.removeFromSuperview()
self.view = self.webView
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
you have to conform to it's protocol delegate by putting this line of code in viewDidLoad
webView?.uiDelegate = self
after doing that , now if you want to use delegation method's you have to put your viewController as a subclass of UIWebViewDelegate
class ViewController: UIViewController ,UIWebViewDelegate{
I fixed this by making
webView?.navigationDelegate = self
and adding this to the Class
class ViewController: UIViewController, WKNavigationDelegate
here is my BorderView and The task I'm trying to do is to hookup the custom object (Border) to the main storyboard.
import UIKit
protocol BorderViewDataSource: class{
func colorForBorderView(sender:BorderView) -> String? }
class BorderView: UIView {
#IBOutlet weak var topLeftImage: UIImageView!
#IBOutlet weak var topRightImage: UIImageView!
#IBOutlet weak var bottomLeftImage: UIImageView!
#IBOutlet weak var bottomRightImage: UIImageView!
var view: UIView!
weak var dataSource:BorderViewDataSource?
override init(frame: CGRect) {
super.init(frame: frame)
xtraSetup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
xtraSetup()
}
func xtraSetup() {
view = loadViewFromNib()
// use bounds not frame or it'll be offset
view.frame = bounds
// Make the view stretch with containing view
view.autoresizingMask = [UIViewAutoresizing.FlexibleWidth, UIViewAutoresizing.FlexibleHeight]
// Adding custom subview on top of our view (over any custom drawing > see note below)
addSubview(view)
let borderColor = dataSource?.colorForBorderView(self) ?? "red"
applyColor(borderColor)
}
// this is an actual load from nib module
func loadViewFromNib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "BorderView", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
return view
}
func applyColor(borderColor:String){
var imageName = "border-topleft-\(borderColor)"
topLeftImage.image = UIImage(named: imageName)
imageName = "border-topright-\(borderColor)"
print("Border color is \(borderColor), and Last image name is \(imageName)")
}
}
So when i open the app it will show the image of different color depending on what the value of the color is set in the ViewContorller.swift and here is my viewcontroller. swift code
class ViewController: UIViewController, BorderViewDataSource {
var borderType = 2
#IBOutlet weak var borderView: BorderView!{
didSet{
borderView.dataSource = self
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func colorForBorderView(sender: BorderView) -> String? {
var borderColor = "blue"
switch borderType {
case 1: borderColor = "blue"
case 2: borderColor = "purple"
case 3: borderColor = "red"
default: break
}
print("Border Type is \(borderType), and border color is \(borderColor)")
return borderColor
}
}
but colorForBorderView method is not calling when i running the app
It seems when the view is initialized, the dataSource property of that view is nil. And you only call that method during initialization of your view. You can apply the color after viewDidLoad() in your view controller
From the documentation:
When you assign a default value to a stored property, or set its
initial value within an initializer, the value of that property is set
directly, without calling any property observers.
That's the reason why the datasource is not set. Put the line borderView.dataSource = self into viewDidLoad()
I'm trying to build an application in Swift for OS X (With Xcode 6.1 GM) that is a MenuBar agent with a single window for preferences.
Though I've been able to get most of my menubar functionality working, it all exists in the AppDelegate and looks pretty messy.

Currently, the IBAction of the downloadButton in my view will call the function within the DownloadController. But ideally I would like to be able to have the IBAction of downloadPressed right within the DownloadController.swift file, but I cannot seem to figure out how to go about this..
Thanks!
Create a XIB file or use storyboard and set it's file owner as your UI view controller. Then setup your actions and outlets there. I would recommend you watch some videos on you tube before you proceed.
I have made a statusBar application with a drop down. I would like to open a settingsWindow from that dropdown. I have made the settings window with its own ViewController.
The issue is that i can't figure out how to instantiate and show the settingsWindow that i have made. I have tried to follow every thread on the internet without any success.
My Viewcontroller:
class SettingsViewController: NSViewController {
#IBOutlet var ipAddress: NSTextField!
#IBOutlet var port: NSTextField!
#IBAction func connect(sender: AnyObject) {}
override func viewDidLoad() {
super.viewDidLoad()
}
}
My AppDelegate:
class AppDelegate: NSObject, NSApplicationDelegate {
#IBOutlet var statusMenu: NSMenu!
var statusItem: NSStatusItem?
var tcpService: TcpService = TcpService()
func applicationDidFinishLaunching(aNotification: NSNotification?) {
let bar = NSStatusBar.systemStatusBar()
statusItem = bar.statusItemWithLength(20)
statusItem!.menu = statusMenu
statusItem!.image = NSImage(byReferencingFile: NSBundle.mainBundle().pathForResource("16*16", ofType: "png"))
statusItem!.highlightMode = true
tcpService.initOutputStream("192.168.1.1", Port: 8888)
}
func applicationWillTerminate(aNotification: NSNotification?) {
// Insert code here to tear down your application
}
#IBAction func openSettings(sender: AnyObject) {
// open settings for ip and port optional port
}
}
in swift 3:
var myWindow: NSWindow? = nil
let storyboard = NSStoryboard(name: "Main",bundle: nil)
let controller: EditorViewController = storyboard.instantiateController(withIdentifier: "editorViewController") as! ViewController
myWindow = NSWindow(contentViewController: controller)
myWindow?.makeKeyAndOrderFront(self)
let vc = NSWindowController(window: myWindow)
vc.showWindow(self)
For 2022
in your normal Main storyboard, tap to add a new window controller.
tap precisely on the red "X", then the blue circle, and then enter "ExampleID" at the green entry.
in your app's ordinary main view controller, add this
variable:
var otherWindow: NSWindowController?
function:
private func otherWindow() {
let sb = NSStoryboard(name: "Main", bundle: nil)
otherWindow = sb.instantiateController(
withIdentifier: "ExampleID") as! NSWindowController
otherWindow?.showWindow(self)
}
That's it.
Call otherWindow when you want to.
Problem:
Inevitably you will want to set up the otherWindow in a certain way, example, transparent, whatever. Unfortunately this is a whole topic in itself, but you do it like this:
private func otherWindow() {
... as above ...
otherWindow?.window?.ExampleSetup()
}
and then
extension NSWindow {
func ExampleSetup() {
self.styleMask = .borderless
self.collectionBehavior = [.fullScreenPrimary]
self.level = .floating
self.isMovable = false
self.titleVisibility = .hidden
// etc etc etc ..
guard let screen = self.screen ?? NSScreen.main else {
print("what the???")
return
}
self.setFrame(screen.frame, display: true)
// consider also .visibleFrame
}
}
enum Storyboards: String {
case main = "Main"
func instantiateVC<T>(_ identifier: T.Type) -> T? {
let storyboard = NSStoryboard(name: rawValue, bundle: nil)
guard let viewcontroller = storyboard.instantiateController(withIdentifier: String(describing: identifier)) as? T else { return nil}
return viewcontroller
}
}
var ssoLoginController: IDSSOLoginViewController?
var myWindow: NSWindow? = nil
ssoLoginController = Storyboards.main.instantiateVC(IDSSOLoginViewController.self)
myWindow = NSWindow(contentViewController: ssoLoginController!)
myWindow?.makeKeyAndOrderFront(self)
let vc = NSWindowController(window: myWindow)
vc.showWindow(self)
I am not 100% that I fully understand your problem, but assuming that you are using a storyboard (you should if you are starting fresh), adding few lines to your applicationDidFinishLaunching method will help:
var myWindow: NSWindow? = nil
let storyboard = NSStoryboard(name: "Main",bundle: nil)
let controller: SettingsViewController = storyboard?.instantiateControllerWithIdentifier("SettingsViewController") as SettingsViewController
myWindow = controller.window
myWindow?.makeKeyAndOrderFront(self)
Do not forget to set the Storyboard ID in IB (in the example above to SettingsViewController)!
I have a question about swift,
I made a popover controller in a UIViewController,which display a list of books
and when the user click on one of the books, the label on the viewController should be updated with the name of the selected book.
But in my case when I select a name of a book, the label does not update
here is the code :
// View Controller
import UIKit
class ViewController: UIViewController,UIPopoverControllerDelegate {
var popoverController : UIPopoverController? = nil
#IBOutlet var bookName : UILabel
var BookNameString : String?{
didSet{
configureView()
}
}
func configureView() {
// Update the user interface for the detail item.
if let detail = self.BookNameString {
if let label = bookName {
label.text = detail
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func Click(sender : UIButton) {
var tableView:TableViewController = TableViewController(style: UITableViewStyle.Plain)
var popoverContent:UINavigationController = UINavigationController(rootViewController: tableView)
self.popoverController = UIPopoverController(contentViewController: popoverContent)
self.popoverController!.delegate = self
self.popoverController!.presentPopoverFromRect(sender.frame, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
and here is the code of the TableViewController when a row is selected:
// TableViewController
override func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!){
var storyboard = UIStoryboard(name: "Main", bundle: nil)
var details = storyboard.instantiateViewControllerWithIdentifier("ViewController") as ViewController
var keyString = bookSectionKeys[indexPath.section]
var bookValues = book.booksLetters[keyString]!
var selectedBookString = bookValues[indexPath.row]
var selectedBookValues = book.bookDictionary[selectedBookString]!
details.BookNameString = selectedBookString
}
I was able to solve this problem a few weeks ago and I want to share the solution with you :)
I solve it using protocols.
OK Here what I did in details:
First I created a protocol in the view that I want it to display inside the popover and I named the protocol "DismissPopoverDelegate"
protocol DismissPopoverDelegate{
func didSelectBook(SelectedBook:String)
}
Then I declared a variable of type DismissPopoverDelegate and name it "delegate"
var delegate: DismissPopoverDelegate?
Then in the didSelectRowAtIndexMethod:
override func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!){
var keyString = bookSectionKeys[indexPath.section]
var bookValues = book.booksLetters[keyString]!
var selectedBookString = bookValues[indexPath.row]
delegate?.didSelectBook(selectedBookString)
}
After that inside the View that contains the popover (View Controller), I set the delegate of the view:
class ViewController: UIViewController, DismissPopOverDelegate, UIPopoverControllerDelegate{
Then to make the view confirm to the protocol DismissPopOverDelegate, I implement the method "didSelectBook" Inside the view:
func didSelectBook(SelectedBook:String){
popoverController!.dismissPopoverAnimated(true) // This is Optional
bookName.text = SelectedBook // Make the label text equal to the selected book From the table
}
Finally, I set the delegate to the tableView to View Controller
tableView.delegate = self
That's it :)
Here is the full code of the viewController that contains the popover
import UIKit
class ViewController: UIViewController, DismissPopOverDelegate, UIPopoverControllerDelegate{
#IBOutlet var booksbarButton : UIBarButtonItem
#IBOutlet var bookName : UILabel
var popoverController : UIPopoverController? = nil
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func showTableView(sender : UIBarButtonItem) {
var tableView:TableViewController = TableViewController(style: UITableViewStyle.Plain)
tableView.delegate = self
var popoverContent:UINavigationController = UINavigationController(rootViewController: tableView)
self.popoverController = UIPopoverController(contentViewController: popoverContent)
popoverController!.delegate = self
self.popoverController!.presentPopoverFromBarButtonItem(booksbarButton, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
func didSelectBook(SelectedBook:String){
popoverController!.dismissPopoverAnimated(true)
bookName.text = SelectedBook
}
}
