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'm trying to create a Countdown Timer application that runs in the Menu Bar, with no window or dock icon. I've been building this off of mostly tutorials I find online and I know the code is kind of messy (I plan to clean up after it functions properly). The issue I'm running into. In the AppDelegate I create the StatusBar item with no issue, but I can't figure out how to update it from the viewController. It instead is creating a new StatusBar item.
//AppDelegate info
class AppDelegate: NSObject, NSApplicationDelegate
{
let item = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
let popover = NSPopover()
func applicationDidFinishLaunching(_ aNotification: Notification)
{
menuBarRefresh(self)
}
func menuBarRefresh(_ sender: Any?)
{
if let button = item.button
{
button.image = NSImage(named: NSImage.Name("2"))
//button.title = initialTime.stringValue
button.action = #selector(togglePopover(_:))
}
popover.contentViewController = TimerViewController.freshController()
}
#objc func togglePopover(_ sender: Any?)
{
if popover.isShown
{
closePopover(sender: sender)
}
else
{
showPopover(sender: sender)
}
}
func showPopover(sender: Any?)
{
if let button = item.button
{
popover.show(relativeTo: button.bounds, of: button, preferredEdge: NSRectEdge.minY)
}
}
func closePopover(sender: Any?)
{
popover.performClose(sender)

As it currently works, I get two StatusBar items instead of creating one with the AppDelegate then updating that one from the ViewController.
Yup... Id-10-t error here. Just had to declare 'item' outside the class and all is well. After getting some good sleep and time away from the computer I realized I was not declaring 'item' globally.
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'm trying to setup a sign in page using parse and swift in Xcode but I keep getting an error with 'signInBackgroundWithBlock' how do I make this work?
I keep receiving the message

If you are using swift 1.2 (Xcode 6.3) you need to call the function by:
newUser.signUpInBackgroundWithBlock({(succeeded:Bool, error:NSError?) -> Void in
})
And if you are using swift 1.1 (Xcode 6.1, 6.2) you need to call the function by:
newUser.signUpInBackgroundWithBlock({(succeded:Bool, error:NSError!) -> Void in
})
This is different because of the swift update 1.2 which has changes with using optionals.
Another way is to write it like this:
(Works in old and new swift)
newuser.signUpInBackgroundWithBlock { (succeded, error) -> Void in
}
I try to use the Spring Framework to play a sound when a button is touched.
import UIKit

#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()

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)
}
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
