My speechRecognizer func doesn't seem to be called. I couldn't find anything in the documentation about calling this func.
Any idea what I might be doing wrong? Thanks in advance.
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
let SR:NSSpeechRecognizer = NSSpeechRecognizer()
var commands = ["word","hello"]
override func viewDidLoad() {
super.viewDidLoad()
SR.commands = commands
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
#IBAction func Listen(sender: AnyObject) {
SR.startListening(); print("listening")
}
#IBAction func Stop(sender: AnyObject) {
SR.stopListening()
}
func speechRecognizer(sender: NSSpeechRecognizer,
didRecognizeCommand command: AnyObject?){
if (command as String == "word")
{
println("case word")
}
else if (command as String == "happy")
{
println("case happy")
}
}
}
Set the NSSpeechRecognizerDelegate to self:
SR.delegate = self

I am trying to pass habit object from NewHomeVC to NewCreateHabitVC via delegate and protocol. However the problem is that the delegate does not listen. Can someone show me what I am doing wrong here? Thanks.

let name : String

override func viewDidLoad() {
super.viewDidLoad()
}
func didButtonTapped() {
//no need here
//self.newHomeVCDelegate?.didEditHabit(habit)
//when you present the ViewController you the set the delegate, so he can ping you back once done. Also you need to set the object that you intend to edit
let vc = NewCreateHabitVC()
vc.newHomeVCDelegate = self
vc.habitThatIwantToEdit = myHabit
vc.modalPresentationStyle = .popover
self.present(vc, animated: true)
}
//you have to implement this method in home class
func didEditHabit(_ habit: Habit) {
//this object is the final edited object from NewCreateHabitVC, this will be called on finish button press, here you have it.
}
}
class NewCreateHabitVC: UIViewController, NewHomeVCDelegate {
//but here
var newHomeVCDelegate : NewHomeVCDelegate?
var habitThatIwantToEdit :Habit?
func didEditHabit(_ habit: Habit) {
//
//updateUI(habit: habit)
}
override func viewDidLoad() {

//setViews()
//setDelegates()

This code won't save the text for same reason. How to fix it?
import UIKit
class ViewControllertextview: UIViewController {
#IBOutlet weak var text: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
_ = UserDefaults.standard
let value = UserDefaults.standard.string(forKey: "onekey")
if value != nil{
text.text = value
}
else {
text.text = "Here you can make Notes"
}
}
let defaults = Foundation.UserDefaults.standard
#IBAction func Sbutton(_ sender: Any) {
UserDefaults.standard.set(text.text, forKey: "onekey")
}
#IBAction func ggbutton(_ sender: Any) {
}
}
UserDefaults don't immediately write data to storage. You can try calling UserDefaults.standard.synchronize() to save immediately, right after UserDefaults.standard.set(..
i have added a page view controller and a 3 pages.
I set Transition Style to Scroll and implemented the presentationCount and the presentationIndex method. now i get a black bar with gray/white dots at the bottom of my view. However, but i want the view to goright to the bottom and the make the dots appear over it(without the black background.
How do i do that?
here is my code:
import UIKit
class FilterViewController: UIPageViewController, UIPageViewControllerDataSource {
override func viewDidLoad() {
super.viewDidLoad()
dataSource = self
if let firstViewController = orderedViewControllers.first {
setViewControllers([firstViewController],
direction: .forward,
animated: true,
completion: nil)
}
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
private(set) lazy var orderedViewControllers: [UIViewController] = {
return [self.newViewController(category: "first"),
self.newViewController(category: "second"),
self.newViewController(category: "third")]
}()
private func newViewController(category: String) -> UIViewController {
return UIStoryboard(name: "Main", bundle: nil) .
instantiateViewController(withIdentifier: "\(category)ViewController")
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
guard let viewControllerIndex = orderedViewControllers.index(of: viewController) else {
return nil
}
let previousIndex = viewControllerIndex - 1
guard previousIndex >= 0 else {
return orderedViewControllers.last
}
guard orderedViewControllers.count > previousIndex else {
return nil
}
return orderedViewControllers[previousIndex]
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
guard let viewControllerIndex = orderedViewControllers.index(of: viewController) else {
return nil
}
let nextIndex = viewControllerIndex + 1
let orderedViewControllersCount = orderedViewControllers.count
guard orderedViewControllersCount != nextIndex else {
return orderedViewControllers.first
}
guard orderedViewControllersCount > nextIndex else {
return nil
}
return orderedViewControllers[nextIndex]
}
func presentationCount(for pageViewController: UIPageViewController) -> Int {
return orderedViewControllers.count
}
func presentationIndex(for pageViewController: UIPageViewController) -> Int {
guard let firstViewController = viewControllers?.first,
let firstViewControllerIndex = orderedViewControllers.index(of: firstViewController) else {
return 0
}
return firstViewControllerIndex
}
}
ok, i got it myself. If anyone has the same problem, just override the viewDidLayoutSubviews() of the Page View Controller:
override func viewDidLayoutSubviews() {
let v = self.view
let subviews = v?.subviews
if subviews?.count == 2 {
var sv:UIScrollView?
var pc:UIPageControl?
for t in subviews! {
if t is UIScrollView {
sv = t as! UIScrollView
} else {
pc = t as! UIPageControl
}
}
if(sv != nil && pc != nil) {
sv?.frame = (v?.bounds)!
v?.bringSubview(toFront: pc!)
}
}
super.viewDidLayoutSubviews()
}
I'm new to Swift, and trying my hands with UIWebView app that loads default url, with option to perform quick action and load a different url.
Problem is when I request the quick action url, code executes but the new url is not loading. So I'm missing something in the flow somewhere.
Here is the code:
import UIKit
import WebKit
class ViewController: UIViewController, UIWebViewDelegate {
#IBOutlet var webView: UIWebView!
override func loadView() {
super.loadView()
self.webView = UIWebView()
self.view = self.webView!
}
override func viewDidLoad() {
print("view did load")
super.viewDidLoad()
let url = NSURL(string: "google.com")
let req = NSURLRequest(URL:url!)
webView.loadRequest(req)
webView.delegate = self
}
func loadUrl2() {
loadView()
let url = NSURL(string: "example.com")
print(url)
let req = NSURLRequest(URL:url!)
self.webView!.loadRequest(req)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
I was experimenting and added loadView to loadUrl2, as I was getting
fatal error: unexpectedly found nil while unwrapping an Optional value
before that.
Edited to Include loading secondary link:
Here are the changes and files you'll need to make to the App Delegate
enum ShortcutIdentifier: String {
case OpenNewLink
case OpenBetterLink
init?(fullIdentifier: String) {
guard let shortIdentifier = fullIdentifier.componentsSeparatedByString(".").last else {
return nil
}
self.init(rawValue: shortIdentifier)
}
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if let shortcutItem = launchOptions?[UIApplicationLaunchOptionsAnnotationKey] as? UIApplicationShortcutItem {
handleShortcut(shortcutItem)
return false
}
return true
}
func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
completionHandler(handleShortcut(shortcutItem))
}
private func handleShortcut(shortcutItem: UIApplicationShortcutItem) -> Bool {
let shortcutType = shortcutItem.type
guard let ShortcutIdentifier = ShortcutIdentifier(fullIdentifier: shortcutType) else {
return false
}
return selectLinkForIdentifier(ShortcutIdentifier)
}
private func selectLinkForIdentifier(identifier: ShortcutIdentifier) -> Bool {
guard let mainView = self.window?.rootViewController as? ViewController else {
return false
}
switch identifier {
case .OpenNewLink:
mainView.urlString = "http://www.bing.com"
mainView.loadWebView(mainView.urlString)
return true
case.OpenBetterLink:
mainView.urlString = "http://www.duckduckgo.com"
mainView.loadWebView(mainView.urlString)
return true
}
}
I also made changes in the MainVC
class ViewController: UIViewController, UIWebViewDelegate {
#IBOutlet var webView: UIWebView!
var urlString: String? = nil
override func viewDidLoad() {
super.viewDidLoad()
setUpWebView()
webView.delegate = self
view.addSubview(webView)
}
func setUpWebView() {
webView = UIWebView()
webView.frame = CGRectMake(0, 0, view.frame.width, view.frame.height)
loadWebView(urlString)
}
func loadWebView(var urlString: String?) {
if urlString == nil {
urlString = "http://www.google.com"
}
let url = NSURL(string: urlString!)
let req = NSURLRequest(URL:url!)
webView.loadRequest(req)
}
}
Be sure to add NSAppTransportSecurity dictionary to your .plist and add NSAllowsArbitraryLoads key set to YES.
I tested it and it should work for you.
I try to use the Spring Framework to play a sound when a button is touched.
import UIKit
class ViewController: UIViewController {
//TODO: max, mia, beide arrays und zufallsgenerator und happy day unten mit klick gleich wave
#IBAction func soundButton(sender: AnyObject) {
let mySound : String! = "refresh.wav"
SoundPlayer.play(mySound)
}
#IBOutlet weak var imageView: SpringImageView!
#IBAction func beideButton(sender: AnyObject) {
imageView.image = UIImage(named: "b1")
imageView.animation = "zoomIn"
imageView.animate()
}
#IBAction func maxButton(sender: AnyObject) {
imageView.image = UIImage(named: "max1")
imageView.animation = "slideLeft"
imageView.animate()
}
#IBAction func miaButton(sender: AnyObject) {
imageView.image = UIImage(named: "mia1")
imageView.animation = "slideRight"
imageView.animate()
}
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.
}
}
I get the following error: Cannot invoke 'play' with an argument list of type ('String')
I tried view things like as!, as String, as String!, as? String to unwrap or so but can not figure it out...
Here is the SoundPlayer class (Copyright (c) 2015 James Tang (j#jamztang.com):
import UIKit
import AudioToolbox
public class SoundPlayer: NSObject {
#IBInspectable var filename : String?
#IBInspectable var enabled : Bool = true
private struct Internal {
static var cache = [NSURL:SystemSoundID]()
}
public func playSound(soundFile:String) {
if !enabled {
return
}
if let url = NSBundle.mainBundle().URLForResource(soundFile, withExtension: nil) {
var soundID : SystemSoundID = Internal.cache[url] ?? 0
if soundID == 0 {
AudioServicesCreateSystemSoundID(url, &soundID)
Internal.cache[url] = soundID
}
AudioServicesPlaySystemSound(soundID)
} else {
println("Could not find sound file name `\(soundFile)`")
}
}
#IBAction public func play(sender: AnyObject?) {
if let filename = filename {
self.playSound(filename)
}
}
}
Judging by the code alone (I'm not familiar with Spring), what you need to do is create a SoundPlayer instance and call playSound on it (not play, which uses an internal filename for the sound to play instead of its argument), like this:
#IBAction func soundButton(sender: AnyObject) {
let mySound : String! = "refresh.wav"
let soundPlayer = SoundPlayer()
soundPlayer.playSound(mySound)
}
