var datePickerView: UIDatePicker = UIDatePicker()
override func viewDidLoad() {
super.viewDidLoad()
initializeBarButtons() }
func initializeBarButtons() {
datePickerView.datePickerMode = UIDatePickerMode.date // This is the line that gets the error
datePickerView.addTarget(self, action: #selector(EmployeeDetailEditViewController.handleDatePicker), for: UIControlEvents.valueChanged)
}
This commented line is causing the crash when the calendar is changed from Gregorian to Buddhist.

How to Solve This ?
Unfortunately, you can't solve it, as there is an open radar on it (https://openradar.appspot.com/41120005).
Meanwhile, use #Amey workaround:
if #available(iOS 11.0, *) {
let gregorianCalendar = Calendar(identifier: .gregorian)
self.datePickerView.calendar = gregorianCalendar
} else {
// Fallback on earlier versions
}

I'm trying to embed an youtube video in swiftUI app (building for iOS 14)
i'm using CocoaPods with the following Podfile:
# Uncomment the next line to define a global platform for your project
platform :ios, '14.0'
target 'TestProjectYoutube' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# Pods for TestProjectYoutube
pod 'Alamofire', '~> 5.0'
pod 'SwiftyJSON', '~> 4.0'
pod 'URLImage'
pod 'Introspect'
end
I've created the following view
import SwiftUI
import CoreData
struct ContentView: View {
#Environment(\.managedObjectContext) private var viewContext
var body: some View {
VStack() {
VideoView(videoID: "CX-BdDHW0Ho")
}
}
}
struct VideoView: UIViewRepresentable {
let videoID: String
func makeUIView(context: Context) -> WKWebView {
let webView = WKWebView(frame: CGRect(x: 0.0, y: 0.0, width: 0.1, height: 0.1))
return webView
}
func updateUIView(_ uiView: WKWebView, context: Context) {
guard let youtubeURL = URL(string: "https://www.youtube.com/embed/\(videoID)") else { return }
uiView.scrollView.isScrollEnabled = false
uiView.load(URLRequest(url: youtubeURL))
}
}
The error i got is:

When I replace the youtube.com with google.com, i dont get the error and google is loaded.
Can someone help me with this?
Why is this code causing a SIGABT error?
#IBAction func showDial(_ sender: Any) {
var dialBottom:CGFloat = lcDialBottom!.constant
if dialBottom == -600 {
//move up
dialBottom = -400
} else {
//move down
dialBottom = -600
}
UIView.animate(withDuration: 0.3,
animations: {
self.lcDialBottom.constant = dialBottom
self.view.layoutIfNeeded()
self.view.updateConstraintsIfNeeded()
self.btnShowDial.alpha = 0.0
})
}
Error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSLayoutConstraint setAlpha:]: unrecognized selector sent to instance 0x600002ff8d70'
I understand what the error is saying, NSLayoutConstraint does not have a setAlpha method, but I'm not calling it on a NSLC, I'm calling set alpha on a UIButton, which does have a setAlpha.
Here's my properties:
#IBOutlet weak var btnShowDial: UIButton!
#IBOutlet weak var lcDialBottom: NSLayoutConstraint!
Check connection of btnShowDial in storyboard. Maybe you connected this IBOutlet with layout constraint.
My app crashes and throws this error

I'm trying to make a custom class for hide and show password so that I can use it in any UITextField in any UIViewController.
class HideShowIcon:NSObject {
var showPasswordImage = UIImage(named: "ic_show_password") as UIImage?
var hidePasswordImage = UIImage(named: "ic_hide_password") as UIImage?
func hideShowPasswordButton(hideText:UITextField) {
var hideShowSize: CGSize = "12345".sizeWithAttributes([NSFontAttributeName:UIFont.systemFontOfSize(14.0)])
var hideShow: UIButton = UIButton(type: UIButtonType.System)
hideShow.frame = CGRect(x: 0, y: 0, width: hideShowSize.width, height: hideText.frame.size.height)
hideShow.setImage(hidePasswordImage, forState: UIControlState.Normal)
hideText.rightView = hideShow
hideText.rightViewMode = UITextFieldViewMode.Always
hideShow.addTarget(self, action: #selector(HideShowIcon.hideShowPasswordTextField(_:hideText:)), forControlEvents: UIControlEvents.AllTouchEvents)
}
func hideShowPasswordTextField(sender: AnyObject,hideText:UITextField) {
var hideShow: UIButton = (hideText.rightView as? UIButton)!
if !hideText.secureTextEntry {
hideText.secureTextEntry = true
hideShow.setImage(hidePasswordImage, forState: UIControlState.Normal)
} else {
hideText.secureTextEntry = false
hideShow.setImage(showPasswordImage, forState: UIControlState.Normal)
}
hideText.becomeFirstResponder()
}
}
You can not use selector with many parameters hideShowPasswordTextField(_:hideText:) for UIButton target. You can only use selector with one (or zero) parameter, in which UIButton will put itself: hideShowPasswordTextField(_:)
func hideShowPasswordTextField(sender: UIButton) {
//...
}
To use hideText in this function, you may declare it as property of your class:
var hideText: UITextField!
and assign value to it in class initialization step
I'm currently working with Swift in SpriteKit to make a small/basic mini game, and I'm running into the error displayed in the title above...
Most of the time, everything works fine, but every once in a while, I get this error (the majority of the times it happens, it's right when the game over function seen below gets called). The error always points to the following line:
func handle_tilt(acceleration_data: CGFloat)
{
if ((childNodeWithName("hero")) != nil){
childNodeWithName("hero")?.physicsBody?.applyForce(CGVectorMake(acceleration_data * 50, 0))
}
}
How can I fix this?
**the code for the accelerometer set up below is contained in the
if motionManager.accelerometerAvailable == true {
self.motionManager.startAccelerometerUpdatesToQueue(NSOperationQueue()) {
(data, error) in
if (data.acceleration.y != 0) {
self.motionManager.accelerometerActive == true
self.handle_tilt(CGFloat(data.acceleration.y))
}
}
}
The function which, when called, triggers the error...
func game_over()
{
self.removeActionForKey("spawn_flying_squirrels")
self.removeActionForKey("spawn_flying_squirrels")
println("Removed the actions")
self.motionManager.stopAccelerometerUpdates()
println("removed motion manager")
if let recognizers = self.view?.gestureRecognizers {
for recognizer in recognizers {
self.view!.removeGestureRecognizer(recognizer as! UIGestureRecognizer)
}
}
println("removed the gesture recognizers")
//saves the score or doesn't (if it doesn't make the high score
saveScore(score)
for child in self.children as! [SKNode]
{
removeChildrenInArray([child])
}
println("removed the children")
let scene = GameScene(size: self.size)
scene.scaleMode = .AspectFill
NSLog("HE DEAD")
view?.presentScene(scene)
}
What I think is happening is that the game_over function deletes the "hero" node, and then the handle_tilt function tries unsuccessfully to access "hero" leading to a meltdown. I tried to prevent it with the if statement in the handle_tilt function, but it wasn't a complete success like I had hoped...
I'm using the following library:
https://github.com/lukabernardi/LBBlurredImage
This is the code I'm using to blur my background image that I'm adding to a ViewController:
var background = UIImage(named: "bg")
var backgroundImageView = UIImageView(image: background)
backgroundImageView.contentMode = .ScaleAspectFill;
backgroundImageView.setImageToBlur(background, blurRadius: 10, completionBlock: { () -> Void in
println("The blurred image has been set")
})
self.view.addSubview(backgroundImageView)
I'm getting the following error and I'm not sure why:
-[UIImageView setImageToBlur:blurRadius:completionBlock:]: unrecognized selector sent to instance 0x7ff08a802390
2015-01-27 10:50:44.326 TestApp[9289:66346] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView setImageToBlur:blurRadius:completionBlock:]: unrecognized selector sent to instance 0x7ff08a802390'
UPDATE:
Looks like I'm not the only one to receive the error.
Exception was that the image I was passing was nil and in turn it was violating NSParameterAssert(image);
var background = UIImage(named: "bg")
Instead of this try to specify the full path of the image.
It worked for me and I am pretty sure it will work for you too.
You can also try this path with your code
var background = UIImage(named: "Images/bg");
