I am making a program to determine whether a number is prime or not. I had a working code on myPlayground , and when i implemented it into Xcode i got this error.
class AppDelegate: UIResponder, UIApplicationDelegate{ 'Thread 1 SIGBART'
This error has happened before, even when i seem to write the code correctly. Please check for any error in my code and give me some solutions. This is only the first part which determines if the number is prime to test whether it would work or not, the other part of the code will be implemented when the problem is resolved.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var enteredNumber: UITextField!
#IBOutlet weak var resultLabel: UILabel!
#IBAction func CheckIfPrime(sender: AnyObject) {
var n = enteredNumber.text.toInt()!
while n != 2 && n % 2 != 0 {
for var i = 2; i <= n; i + 1 {
if n % i != 0 {
var v = resultLabel.text
v = "Is Prime"
}
}
}
}
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.
}
}
SIGBART errors occur when your code references an object that is inexistent. Go to you IB storyboard(where your labels, buttons, and text fields are) and click on any item that is linked to your view controller. For each one, click on the right most item of the inspector(the arrow within the circle) If you see more than one connection, that is why the error happens. Delete any connections that you think should not be there. (Or, just to be safe, delete all connections and manually reconnect everything by right clicking the UI element and drag to the IBOutlet/Action name)

I have been experimenting with mouse clicks. I am ok with left mouse clicks getting raw values etc etc. I now want to add right mouse clicks. I have setup a basic example. What i would like to achieve if there is one mouse right click it performs one function, and if there is two mouse right clicks it performs a different function. The problem is if you do two mouse clicks it obviously cannot differentiate between the two and so fire the one mouse click function before performing the second mouse function.
I was thinking of maybe using a timer of some sort to record the number of click. But i end up going round in circles as i just seem to start the timers over and over. I'm hoping some one might help. thanks for reading here is the code.

class MainWindowController: NSWindowController {
#IBOutlet weak var MyView: NSView!
override func windowDidLoad() {
super.windowDidLoad()
//Initialize mouse for Right Click numberOfClicksRequired = 1

recogRightClick1.buttonMask = 0x2
recogRightClick1.numberOfClicksRequired = 1
MyView.addGestureRecognizer(recogRightClick1)
//Initialize mouse for Right ClicknumberOfClicksRequired = 2
let recogRightClick2 = NSClickGestureRecognizer(target: self, action: #selector(twoMouseClick(myrec:myRightClick:)))
recogRightClick2.buttonMask = 0x2
recogRightClick2.numberOfClicksRequired = 2
MyView.addGestureRecognizer(recogRightClick2)
}//EO Overide
func oneMouseClick(myrec: NSPanGestureRecognizer,myRightClick:NSClickGestureRecognizer){
let rightClick = myRightClick.state.rawValue
print("oneMouseClick",rightClick)
}
func twoMouseClick(myrec: NSPanGestureRecognizer,myRightClick:NSClickGestureRecognizer){
let rightClick = myRightClick.state.rawValue
print("twoMouseClick",rightClick)
}
}//EnD oF thE wORld
UPDATE
I have re generated the code following the advice given. Now the code reflects more of what i wanted to do. My only problem is that I would like all the mouse operations to be triggered only inside 'myView' rather than within the main window. I thought it might have something to do with first responder but that doesn't seem to work. Again any thought would be appreciated. Please excuse any bad code i'm self taught.

UPDATE 2
I have now updated subClassing the view controller, so the mouse clicks are now only working in myView. I'm still having problems with 'func mouseDragged' What i need to achieve is the bottom left of my view is x = 0 and Y = 0. I had a try with converting but thats not working. hoping someone might guide me. thanks for reading here is the updated code.

To define mouse inside view you use
let myLocationInWindow = theEvent.locationInWindow
let location = convert(myLocationInWindow, from: nil)
where nil is the window
here is the final code

I am trying to write an alarm clock like the new Bedtime feature of IOS 10 but I am fairly new to Swift. I have 2 UISliders: one is for when to sleep and the other when to wake up. My question is: How can I combine the two UISliders? and how can I make it count minutes and hours? Is it possible to have gridlines and stop points in the slider? My idea is to have increments of 0.12 and whenever the value reaches 0.60, I would count it as 1 hour and "..." minutes.
EDIT: Added image and code
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var sleepTime: UISlider!
#IBOutlet weak var displaySleep: UITextField!
var sliderValue1 = 12
var sliderValue2 = 12
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func slider1Changed(_ sender: UISlider!) {
var currentValue1 = Int(sender.value)
displaySleep.text = "\(sliderValue2 - currentValue1) hours of sleep"
}
#IBAction func slider2Changed(_ sender: UISlider!) {
var currentValue2 = Int(sender.value)
displaySleep.text = "\(currentValue2 - sliderValue1) hours of sleep"
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
To answer your first question.
You can combine the two sliders by utilizing a Segmented Control. When the user selects either "Sleep" or "Wake Up" it will change the Slider values accordingly upon implementation.
Control click then drag from your segmented control to your View Controller class to create a IBAction connection. Make sure to change the type to UISegmentedControl.
#IBAction func onControlChanged(_ sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0: // Sleep selected
// Update Slider
break
case 1: // Wake Up selected
// Update Slider
break
default:
break
}
}
I just have a strange trouble. I written a test app, that searches min & max of array values. In first times apps works normally, but only had a warning: "Array MinMax[554:5057] Failed to connect (exitNow) outlet from (Array_MinMax.ViewController) to (NSButton): missing setter or instance variable"
Now, several days later, i started app again, enter some values, pushed button and app instantly crush with same error:
2016-06-15 12:11:40.910 Array MinMax[829:18846] Failed to connect (exitNow) outlet from (Array_MinMax.ViewController) to (NSButton): missing setter or instance variable
(lldb)
Here is the code:
import Cocoa
class ViewController: NSViewController {
#IBOutlet weak var inputArrayValues: NSTextField!
#IBOutlet weak var minLabel: NSTextField!
#IBOutlet weak var maxLabel: NSTextField!
#IBAction func exitNow(sender: AnyObject) {
NSApplication.sharedApplication().terminate(self)
}
#IBAction func arrayMinMax(sender: AnyObject) {
let someData: String? = inputArrayValues.stringValue
let separators = NSCharacterSet(charactersInString: " ,;:|")
let parts = someData!.componentsSeparatedByCharactersInSet(separators)
let intArray = parts.map{Double($0)}
let minArray = intArray.minElement({$0 < $1}) // - stops on that line (thread 1: breakpoint 1.1)
let maxArray = intArray.maxElement({$0 < $1})
let minString = String(minArray!)
let maxString = String(maxArray!)
minLabel.stringValue = "The minimal value is \(minString)!"
maxLabel.stringValue = "The maximal value is \(maxString)!"
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}
What to do with that, i can't understand! Is it a bug of Xcode 7.3.1??
Already solved this trouble. Just recreated the button using "NSButton" instead of "Any Object". Then, error goes away!
I'm trying to build a very simple app just to see how the UISlider works. I've seen several tutorials and followed them to the letter but nothing seems to work.
I keep getting this error exactly when I try to move the Slider in the simulator, after I've successfully built
This is my whole code. It's really simple but I can't understand why the Slider won't work.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var noteBottomLabel: UILabel!
#IBOutlet weak var sliderNoteBottom: UISlider!
#IBAction func changedSliderNoteBottom(sender: AnyObject) {
var noteBottomValue = Int(sliderNoteBottom.value)
noteBottomLabel.text = "\(noteBottomValue)"
}
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.
}
Can you see any problems with this? I'm probably noobing out, but I've looked everywhere and can't find an explanation
import UIKit
import CoreFoundation
class ViewController2 : UIViewController {
override func viewDidLoad() {
super.viewDidLoad();
}
#IBOutlet weak var slider: UISlider!
#IBAction func slidervaluechanged(sender: UISlider) {
print(Int(slider.value))
}
}
I have tried your code just made the print of slider.value rather than putting it on label .
But I have used Xcode 7.3 , I don't think this should be problem with Xcode .Use the sender as UISlider when making an #IBAction that looks better . Brings up the value of 0 at bottom and 1 at top.
I am new to Mac OSX and with Apple promoting the fact that the bodies of code are becoming similar decided to tell the folk I am writing code for we should be able to do a Mac OSX version. iPhone and iPad versions are all good and about to release second version so no issues there.
So I am subclassing NSWindowController to get access to the Toolbar and worked out how to remove and add items on the toolbar, but for the life of me I can not get one NSViewController (firstViewController) to dismiss and bring up the second NSViewController (secondViewController) in the same NSWindowController.
So the 2 issues are that
1. I want to be able to performSegueWithIdentifier from the first NSViewController in code and
2. bring up the second NSViewController by replacing the first NSViewController in the same NSWindowController.
If I add a button to the firstViewController and put a segue to the secondViewController then when I select the button the secondViewController comes up just fine but in a seperate window not the same NSWindowController that I want it to and the firstViewController does not get replaced but stays in the NSWindowController.
So I know the segue idea will work but its not working in code and when I do insert the segue from a button it works but into a seperate NSViewController that is not part of the NSWindowController.
I am trying to find some programming guide from Apple on the issue but no luck so far.
Here is an overview from my Storyboard:
Here is my NSWindowController subclassed and the func loginToMe2Team is trigger from the NSToolBar and its working just find as the print statements show up on the console.
import Cocoa
class me2teamWindowsController: NSWindowController {
#IBOutlet var mySignUp : NSToolbarItem!
#IBOutlet var myToolbar : NSToolbar!
let controller = ViewController()
override func windowDidLoad() {
super.windowDidLoad()
print("window loaded")
}
override func windowWillLoad() {
print("window will load")
}
#IBAction func logInToMe2Team(sender: AnyObject){
controller.LogIn() //THIS IS THE FUNC I AM TESTING WITH
}
#IBAction func signUpToMe2Team(sender: AnyObject){
controller.signUp()
}
Here is my NSViewController subclassed with the func LogIn. Its getting selected just fine but the performSegueWithIdentifier is not. And I did cut and past the Identifier to make absolutely sure it was the same.
import Cocoa
import WebKit
class ViewController: NSViewController {
#IBOutlet weak var theWebPage: WebView!
#IBOutlet weak var progressIndicator: NSProgressIndicator!
override func viewDidLoad() {
super.viewDidLoad()
let urlString = "https://thewebpage.com.au"
self.theWebPage.mainFrame.loadRequest(NSURLRequest(URL: NSURL(string: urlString)!))
}
override func viewDidAppear() {
}
func LogIn() {
print("I logged in")
self.performSegueWithIdentifier("goToTeamPage", sender: self)
//THIS IS THE BIT THATS NOT WORKING
}
func signUp() {
print("I have to sign up now")
}
override var representedObject: AnyObject? {
didSet {
}
}
func webView(sender: WebView!, didStartProvisionalLoadForFrame frame: WebFrame!)
{
self.progressIndicator.startAnimation(self)
}
func webView(sender: WebView!, didFinishLoadForFrame frame: WebFrame!)
{
self.progressIndicator.stopAnimation(self)
}
}
You need to use a custom segue class (or possibly NSTabViewController if it’s enough for your needs). Set the segue’s type to Custom, with your class name specified:
…and implement it. With no animation, it’s simple:
class ReplaceSegue: NSStoryboardSegue {
override func perform() {
if let src = self.sourceController as? NSViewController,
let dest = self.destinationController as? NSViewController,
let window = src.view.window {
// this updates the content and adjusts window size
window.contentViewController = dest
}
}
}
In my case, I was using a sheet and wanted to transition to a different sheet with a different size, so I needed to do more:
class ReplaceSheetSegue: NSStoryboardSegue {
override func perform() {
if let src = self.sourceController as? NSViewController,
let dest = self.destinationController as? NSViewController,
let window = src.view.window {
// calculate new frame:
var rect = window.frameRectForContentRect(dest.view.frame)
rect.origin.x += (src.view.frame.width - dest.view.frame.width) / 2
rect.origin.y += src.view.frame.height - dest.view.frame.height
// don’t shrink visible content, prevent minsize from intervening:
window.contentViewController = nil
// animate resizing (TODO: crossover blending):
window.setFrame(window.convertRectToScreen(rect), display: true, animate: true)
// set new controller
window.contentViewController = dest
}
}
}
