Im writing on a command line tool that shows a pop up window.
Of course programmatically.
In this pop up window I show two text fields, one for the username and the other for password. But when I try to type text in one of them, it wont work. I can select the textField and everything but when I try to type text it wont show up
Can anyone help me please
Edit:
Here's the code:
main.swift:
import Foundation
import AppKit
let app = NSApplication.sharedApplication()
let con = TestApplicationController()
app.delegate = con
app.run()
window.swift:
import Foundation
import AppKit
final class TestApplicationController: NSObject, NSApplicationDelegate {
let window1 = NSWindow()
let view = NSView()
func applicationDidFinishLaunching(aNotification: NSNotification) {
window1.setFrame(CGRect(x: 0, y: 0, width: 443, height: 229), display: true)
window1.contentView = view
window1.opaque = false
window1.center()
window1.makeKeyAndOrderFront(self)
window1.title = "Finder"
window1.level = Int(CGWindowLevelForKey(.MaximumWindowLevelKey))

How to truncate or word wrap the value label in Pie Chart ?
I am using Charts Library in iOS.
If I add extra offset the pie chart shrink in smaller devices like iPhone 5s or iPhone SE.
If the text is large then the text goes out of the screen as you can see in the uploaded image. I am not able to find any properties (word wrap) to handle the large text issue.
here is the code i use to try to add a textfield into an nsmenuitem
class menuitemtest1: NSTextField {
var menuitemtest1 = NSTextField()
override func viewDidChangeBackingProperties() {
menuitemtest1.frame = CGRect(x: 220, y: 8, width: 103, height: 17)
menuitemtest1.stringValue = "Maximum Lenght"
menuitemtest1.isEditable = false
menuitemtest1.textColor = .gray
menuitemtest1.isSelectable = false
menuitemtest1.drawsBackground = false
}
}
thats the class
and how i add it
var textFieldInMenutest = NSMenuItem()
menuBarMenu.addItem(textFieldInMenutest)
textFieldInMenutest.view = menuitemtest1()
You created an NSTextField subclass which has as a property, a separate and direct NSTextField instance. This makes no sense. What you intended to do, was this:
class menuitemtest1: NSTextField {
override func viewDidChangeBackingProperties() {
self.frame = CGRect(x: 220, y: 8, width: 103, height: 17)
self.stringValue = "Maximum Lenght"
self.isEditable = false
self.textColor = .gray
self.isSelectable = false
self.drawsBackground = false
}
}
As for why it "doesn't show up" — the text field you did add as the menu item's view has a zero-sized (default) frame, so it's simply invisible.
Further, viewDidChangeBackingProperties is not the correct place to set up basic properties of the field. In such a subclass, you should use the initializer, init(frame:... or init(coder: ...
I am trying to setup a line chart with one fill colour but for some reason, the fill colour is faded.
Example
Both the random view I have added to middle of screen and the fill colour of the line chart are set to be red, but for some reason the fill colour of the chart is faded.
Can see code here
#IBOutlet var liveChart : LineChartView!
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Chart Tests"
configureChart(chart: liveChart)
var xAxis = [String]()
var yAxis = [Double]()
for _ in 0..<10
{
xAxis.append("")
let yVal = Double(randomBetweenNumbers(firstNum: 1.0, secondNum: 100.0))
yAxis.append(yVal)
}
setData(xAxisArray: xAxis, yAxisArray: yAxis, chart: liveChart)
let testView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
testView.center = view.center
testView.backgroundColor = UIColor.red
view.addSubview(testView)
}
func randomBetweenNumbers(firstNum: CGFloat, secondNum: CGFloat) -> CGFloat{
return CGFloat(arc4random()) / CGFloat(UINT32_MAX) * abs(firstNum - secondNum) + min(firstNum, secondNum)
}
func configureChart(chart : LineChartView)
{
chart.chartDescription?.text = ""
chart.noDataText = "Loading Data"
chart.backgroundColor = UIColor.clear
chart.drawGridBackgroundEnabled = false
chart.dragEnabled = true
chart.rightAxis.enabled = false
chart.leftAxis.enabled = true
chart.doubleTapToZoomEnabled = false
chart.legend.enabled = false
chart.pinchZoomEnabled = true
chart.highlightPerTapEnabled = false
chart.highlightPerDragEnabled = false
chart.xAxis.enabled = false
chart.leftAxis.drawAxisLineEnabled = false
chart.leftAxis.drawGridLinesEnabled = false
chart.leftAxis.labelCount = 5
chart.leftAxis.forceLabelsEnabled = true
}
func setData(xAxisArray : [String], yAxisArray : [Double], chart : LineChartView)
{
var yVals1 : [ChartDataEntry] = [ChartDataEntry]()
if(xAxisArray.count > 0)
{
for i in 0 ..< xAxisArray.count
{
let chartEntry = ChartDataEntry(x: Double(i), y: yAxisArray[i], data: nil)
yVals1.append(chartEntry)
}
}
let set1: LineChartDataSet = LineChartDataSet(values: yVals1, label: "")
set1.fillColor = UIColor.red
set1.drawFilledEnabled = true
set1.drawCirclesEnabled = false
let data = LineChartData()
data.addDataSet(set1)
liveChart.data = data
}
Is there a way to fix this? Or is this just the way the fill colour of the chart works?
Edit:
I am using
https://github.com/danielgindi/Charts
I assume you use this library: https://github.com/kevinbrewster/SwiftCharts
So the LineChartView automatically set alpha for the fill color: https://github.com/kevinbrewster/SwiftCharts/blob/master/SwiftCharts/LineChart.swift#L758
try to set fillAlpha property of the data set
I am trying to display badge on my notification button, in app as displayed on AppIcon.
So far whatever i have researched is related to Obj. C, but nothing that specifically discussed way to implement that solution into Swift,
Please help to find a solution to add a custom class / code to achieve Badge on UiBarbutton and UiButton.
Researched so far:
https://github.com/Marxon13/M13BadgeView
along with MKBadge class etc.
There is a more elegant solution with an extension for UIButtonItem
extension CAShapeLayer {
func drawCircleAtLocation(location: CGPoint, withRadius radius: CGFloat, andColor color: UIColor, filled: Bool) {
fillColor = filled ? color.cgColor : UIColor.white.cgColor
strokeColor = color.cgColor
let origin = CGPoint(x: location.x - radius, y: location.y - radius)
path = UIBezierPath(ovalIn: CGRect(origin: origin, size: CGSize(width: radius * 2, height: radius * 2))).cgPath
}
}
private var handle: UInt8 = 0
extension UIBarButtonItem {
private var badgeLayer: CAShapeLayer? {
if let b: AnyObject = objc_getAssociatedObject(self, &handle) as AnyObject? {
return b as? CAShapeLayer
} else {
return nil
}
}
func addBadge(number: Int, withOffset offset: CGPoint = CGPoint.zero, andColor color: UIColor = UIColor.red, andFilled filled: Bool = true) {
guard let view = self.value(forKey: "view") as? UIView else { return }
badgeLayer?.removeFromSuperlayer()
// Initialize Badge
let badge = CAShapeLayer()
let radius = CGFloat(7)
let location = CGPoint(x: view.frame.width - (radius + offset.x), y: (radius + offset.y))
badge.drawCircleAtLocation(location: location, withRadius: radius, andColor: color, filled: filled)
view.layer.addSublayer(badge)
// Initialiaze Badge's label
let label = CATextLayer()
label.string = "\(number)"
label.alignmentMode = CATextLayerAlignmentMode.center
label.fontSize = 11
label.frame = CGRect(origin: CGPoint(x: location.x - 4, y: offset.y), size: CGSize(width: 8, height: 16))
label.foregroundColor = filled ? UIColor.white.cgColor : color.cgColor
label.backgroundColor = UIColor.clear.cgColor
label.contentsScale = UIScreen.main.scale
badge.addSublayer(label)
// Save Badge as UIBarButtonItem property
objc_setAssociatedObject(self, &handle, badge, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
}
func updateBadge(number: Int) {
if let text = badgeLayer?.sublayers?.filter({ $0 is CATextLayer }).first as? CATextLayer {
text.string = "\(number)"
}
}
func removeBadge() {
badgeLayer?.removeFromSuperlayer()
}
}

https://gist.github.com/freedom27/c709923b163e26405f62b799437243f4
Working Solution :
Step 1:
Firstly create new swift file which is a subclass to UIButton as follows:
import UIKit
class BadgeButton: UIButton {
var badgeLabel = UILabel()
var badge: String? {
didSet {
addbadgetobutton(badge: badge)
}
}
public var badgeBackgroundColor = UIColor.red {
didSet {
badgeLabel.backgroundColor = badgeBackgroundColor
}
}
public var badgeTextColor = UIColor.white {
didSet {
badgeLabel.textColor = badgeTextColor
}
}
public var badgeFont = UIFont.systemFont(ofSize: 12.0) {
didSet {
badgeLabel.font = badgeFont
}
}
public var badgeEdgeInsets: UIEdgeInsets? {
didSet {
addbadgetobutton(badge: badge)
}
}
override init(frame: CGRect) {
super.init(frame: frame)
addbadgetobutton(badge: nil)
}
func addbadgetobutton(badge: String?) {
badgeLabel.text = badge
badgeLabel.textColor = badgeTextColor
badgeLabel.backgroundColor = badgeBackgroundColor
badgeLabel.font = badgeFont
badgeLabel.sizeToFit()
badgeLabel.textAlignment = .center
let badgeSize = badgeLabel.frame.size
let height = max(18, Double(badgeSize.height) + 5.0)
let width = max(height, Double(badgeSize.width) + 10.0)
var vertical: Double?, horizontal: Double?
if let badgeInset = self.badgeEdgeInsets {
vertical = Double(badgeInset.top) - Double(badgeInset.bottom)
horizontal = Double(badgeInset.left) - Double(badgeInset.right)
let x = (Double(bounds.size.width) - 10 + horizontal!)
let y = -(Double(badgeSize.height) / 2) - 10 + vertical!
badgeLabel.frame = CGRect(x: x, y: y, width: width, height: height)
} else {
let x = self.frame.width - CGFloat((width / 2.0))
let y = CGFloat(-(height / 2.0))
badgeLabel.frame = CGRect(x: x, y: y, width: CGFloat(width), height: CGFloat(height))
}
badgeLabel.layer.cornerRadius = badgeLabel.frame.height/2
badgeLabel.layer.masksToBounds = true
addSubview(badgeLabel)
badgeLabel.isHidden = badge != nil ? false : true
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.addbadgetobutton(badge: nil)
fatalError("init(coder:) is not implemented")
}
}
Step 2:
Create a function in your base file which u can use in each View Controller :
func addBadge(itemvalue: String) {
let bagButton = BadgeButton()
bagButton.frame = CGRect(x: 0, y: 0, width: 44, height: 44)
bagButton.tintColor = UIColor.darkGray
bagButton.setImage(UIImage(named: "ShoppingBag")?.withRenderingMode(.alwaysTemplate), for: .normal)
bagButton.badgeEdgeInsets = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 15)
bagButton.badge = itemvalue
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: bagButton)
}
Step 3 :
Use above function from any View Controller in this way :
self.addBadge(itemvalue: localStorage.string(forKey: "total_products_in_cart") ?? "0")
First create label, then right bar button. On right bar button add subview which will be badge count. Finally add navigation right bar button.
SWIFT 5
let badgeCount = UILabel(frame: CGRect(x: 22, y: -05, width: 20, height: 20))
badgeCount.layer.borderColor = UIColor.clear.cgColor
badgeCount.layer.borderWidth = 2
badgeCount.layer.cornerRadius = badgeCount.bounds.size.height / 2
badgeCount.textAlignment = .center
badgeCount.layer.masksToBounds = true
badgeCount.textColor = .white
badgeCount.font = badgeCount.font.withSize(12)
badgeCount.backgroundColor = .red
badgeCount.text = "4"
let rightBarButton = UIButton(frame: CGRect(x: 0, y: 0, width: 35, height: 35))
rightBarButton.setBackgroundImage(UIImage(named: "NotificationBell"), for: .normal)
rightBarButton.addTarget(self, action: #selector(self.onBtnNotification), for: .touchUpInside)
rightBarButton.addSubview(badgeCount)
let rightBarButtomItem = UIBarButtonItem(customView: rightBarButton)
navigationItem.rightBarButtonItem = rightBarButtomItem
I had the same task. I didn't want to use third-party libraries. Firstly, I tried Stefano's solution and it's great however I decided to implement my own way to solve it.
In my humble opinion, there are simple steps described below briefly:
Create UIView instance within .xib file and put necessary items like UILabel or UIImageView instance depending on your design requirements.
The final action I did in this step is putting invisible button in the top of view's hierarchy.
Create YourCustomView.swift and link all #IBOutlets from xib to current file inside your custom view class implementation.
Next, implement class function in YourCustomView class which will load custom view from xib and return it as YourCustomView instance.
Finally, add your custom badge to your custom view controller instance!
My result is..
P.S. If you need to implement #IBActions I recommend to link your custom view and custom view controller through the delegate pattern.
using M13BadgeView.. use this code
(im using fontawesome.swift for buttons :: https://github.com/thii/FontAwesome.swift)
let rightButton = UIButton(frame: CGRect(x:0,y:0,width:30,height:30))
rightButton.titleLabel?.font = UIFont.fontAwesome(ofSize: 22)
rightButton.setTitle(String.fontAwesomeIcon(name: .shoppingBasket), for: .normal)
let rightButtonItem : UIBarButtonItem = UIBarButtonItem(customView: rightButton)
let badgeView = M13BadgeView()
badgeView.text = "1"
badgeView.textColor = UIColor.white
badgeView.badgeBackgroundColor = UIColor.red
badgeView.borderWidth = 1.0
badgeView.borderColor = UIColor.white
badgeView.horizontalAlignment = M13BadgeViewHorizontalAlignmentLeft
badgeView.verticalAlignment = M13BadgeViewVerticalAlignmentTop
badgeView.hidesWhenZero = true
rightButton.addSubview(badgeView)
self.navigationItem.rightBarButtonItem = rightButtonItem
Good answer #Julio Bailon (https://stackoverflow.com/a/45948819/1898973)!
Here is the author's site with full explanation: http://www.stefanovettor.com/2016/04/30/adding-badge-uibarbuttonitem/.
It seems not to be working on iOS 11, maybe because the script try to access the "view" property of the UIBarButtonItem. I made it work:
By creating a UIButton and then creating the UIBarButtonItem using the UIButton as a customView:
navigationItem.rightBarButtonItem = UIBarButtonItem.init(
customView: shoppingCartButton)
By replacing the line in the UIBarButtonItem extension:
guard let view = self.value(forKey: "view") as? UIView else { return }
with the following:
guard let view = self.customView else { return }
Seems elegant to me and, best of all, it worked!
You can set below constraints to UILabel with respect to UIButton
align UILabel's top and trailing to UIButton
And when you need to show badge set text to UILabel and when you don't want to show badge then set empty string to UILabel
Download This
For BarButtonItem : Drag and Drop UIBarButtonItem+Badge.h and UIBarButtonItem+Badge.m class in project.
Write this code for set Badges:
self.navigationItem.rightBarButtonItem.badgeValue = "2"
self.navigationItem.rightBarButtonItem.badgeBGColor = UIColor.black
For UIButtton : Drag and Drop UIButton+Badge.h and UIButton+Badge.m class in project.
self.notificationBtn.badgeValue = "2"
self.notificationBtn.badgeBGColor = UIColor.black
Answer with extension from Julio will not work.
Starting from iOS 11 this code will not work cause line of code below will not cast UIView. Also it's counting as private API and seems to be will not pass AppStore review.
guard let view = self.value(forKey: "view") as? UIView else { return }
Thread on Apple Developer Forum
Second thing that this snippet always draws circle, so it can't fit numbers bigger than 9.
Here the simplified version by using custom view
Easy and clear solution if you are looking for only adding the red dot without the number;
private var handle: UInt8 = 0;
extension UIBarButtonItem {
private var badgeLayer: CAShapeLayer? {
if let b: AnyObject = objc_getAssociatedObject(self, &handle) as AnyObject? {
return b as? CAShapeLayer
} else {
return nil
}
}
func setBadge(offset: CGPoint = .zero, color: UIColor = .red, filled: Bool = true, fontSize: CGFloat = 11) {
badgeLayer?.removeFromSuperlayer()
guard let view = self.value(forKey: "view") as? UIView else {
return
}
var font = UIFont.systemFont(ofSize: fontSize)
if #available(iOS 9.0, *) {
font = UIFont.monospacedDigitSystemFont(ofSize: fontSize, weight: .regular)
}
//Size of the dot
let badgeSize = UILabel(frame: CGRect(x: 22, y: -05, width: 10, height: 10))
// initialize Badge
let badge = CAShapeLayer()
let height = badgeSize.height
let width = badgeSize.width
// x position is offset from right-hand side
let x = view.frame.width + offset.x - 17
let y = view.frame.height + offset.y - 34
let badgeFrame = CGRect(origin: CGPoint(x: x, y: y), size: CGSize(width: width, height: height))
badge.drawRoundedRect(rect: badgeFrame, andColor: color, filled: filled)
view.layer.addSublayer(badge)
// initialiaze Badge's label
let label = CATextLayer()
label.alignmentMode = .center
label.font = font
label.fontSize = font.pointSize
label.frame = badgeFrame
label.foregroundColor = filled ? UIColor.white.cgColor : color.cgColor
label.backgroundColor = UIColor.clear.cgColor
label.contentsScale = UIScreen.main.scale
badge.addSublayer(label)
// save Badge as UIBarButtonItem property
objc_setAssociatedObject(self, &handle, badge, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
// bring layer to front
badge.zPosition = 1_000
}
private func removeBadge() {
badgeLayer?.removeFromSuperlayer()
}
}
// MARK: - Utilities
extension CAShapeLayer {
func drawRoundedRect(rect: CGRect, andColor color: UIColor, filled: Bool) {
fillColor = filled ? color.cgColor : UIColor.white.cgColor
strokeColor = color.cgColor
path = UIBezierPath(roundedRect: rect, cornerRadius: 7).cgPath
}
}
The source of the code:
https://gist.github.com/freedom27/c709923b163e26405f62b799437243f4
I only made a few changes to eliminate the number.
The MIBadgeButton-Swift is working also on UIBarButtonItems.
Here is my code after the navigation bar is created:
let rightBarButtons = self.navigationItem.rightBarButtonItems
let alarmsBarButton = rightBarButtons?.last
let alarmsButton = alarmsBarButton.customView as! MIBadgeButton?
alarmsButton.badgeString = "10"
You can do it programmatically with
self.tabBarItem.badgeColor = .red
or use the storyboard. See:
Can anyone help? I have a true or false game, however, I want the questions to be shuffled/random. I know there is previous shuffle answers but I can't get my head around it. For example, the questions in the append section should appear at random. I have been trying different things for days. I had a look at arc4random but I had a hard time implementing it.

I didn't try to wade through your code. It's too much. (tldr)
Here is a general solution. You'll need to adapt it to your needs.
Create a struct that contains a question, the possible answers, and the correct answer (if they are all true/false questions you could skip the possible answers part.) Let's call it questionStruct.
Then create an array of questionStruct structures. Populate it with questions.
Copy the list of all questions into a working array of questions. Let's call it remainingQuestions
Then user arc4random_uniform to select a question at random and remove it from the remaining questions array
let index = arc4random_uniform(remainingQuestions.count)
let aQuestion = remainingQuestions.removeAtIndex(index)
When the remainingQuestions array is empty, repopulate it with the array of all questions to start over.
