I'm pretty new to XCode UI tests and I'm trying to run a test where I fill two text labels and then I press a button. After the button is pressed the app should make an URL call and be redirected to another view controller. I want to check if at the end of this operation the second view controller is displayed.
To test this, I have written the following test:
let app = XCUIApplication()
app.launch()
let ownerTextField = app.textFields["ownerTextField"]
ownerTextField.tap()
ownerTextField.typeText("UserA")
let repositoryTextField = app.textFields["repositoryTextField"]
repositoryTextField.tap()
repositoryTextField.typeText("AppB")
app.buttons["SearchButton"].tap()
XCTAssertTrue(app.isDisplayingResults)
Where isDisplayingResults is
extension XCUIApplication {
var isDisplayingResults: Bool {
return otherElements["resultView"].exists
}
}
I have set up the identifier of the View controller inside its swift file class:
override func viewDidLoad() {
super.viewDidLoad()
view.accessibilityIdentifier = "resultView"
...
Nonetheless to say, the test fails. How can I get a success?
It's so simple.
If after clicking the URL, Viewcontroller is presenting means your previous VC button doesn't exist on screen.
So Just check for previous VC button exists or not.
If app.buttons["SearchButton"].esists()
{ //write if code
} else {
// Write else code
}

I have a problem understanding what I can do with the default Back BarButtonItem and how I can instigate a rewind.
The following shows a simplified layout. I embed a ViewController in a Navigation controller and add a BarButtonItem ("Show") and connect to a second VC. This adds the "Back" button to the second controller as shown below.
In the first VC I will show the user some details, in the second VC greater details will be shown. With the show button and the default back button the user can easily navigate back and forth with expected behavior.
My problem comes in that the user will be allowed to modify the "More Details Here" and I will need to pass that to the first VC after the user unwinds back.
I cannot control-drag from the Back to the Exit icon but I have determined I can do this with a "Save" button on the navigation bar as shown. (First dragging an Navigation Item to the top, then the BarButtonItem) then control-drag to Exit icon.
With the Save button, I can initiate a segue unwind and capture the changes back in my first VC with code like the following.
#IBAction func unwindFromSecondVC(_ sender: UIStoryboardSegue) {
if sender.source is AddCharacterViewController {
if let senderVC = sender.source as? SecondViewController {
details = senderVC.newDetails
}
}
}
This creates a problem when the user makes a change and then clicks the back button thereby loosing the changes.
My preferred solution would be to have the back button initiate a segue and transfer the changes. But this does not appear to be possible. My second solution would be to have the back button notice a transfer has not been made and stop the unwind seque. Neither approach appears possible based on my research.
How should I best handle this problem while giving the user the common Back navigation?
If you want to save any changes the user has made in the second VC, you could create a SecondVCDelegate:
protocol SecondVCDelegate : class {
func detailsDidChange(newDetails: String)
}
In SecondVC, declare a delegate property:
weak var delegate: SecondVCDelegate?
And whenever the details change (the text field's value changed, or whatever event happened), you call
delegate?.detailsDidChange(newDetails: newDetails)
In FirstVC.prepareForSegue, you should set self as the delegate of SecondVC:
if let vc = segue.destination as? SecondVC {
vc.delegate = self
}
// ...
extension FirstVC : SecondVCDelegate {
func detailsDidChange(newDetails: String) {
details = newDetails
}
}
This way, whenever the newDetails change, FirstVC will be notified.
If you just want to notify FirstVC when the user leaves SecondVC, you could instead call the delegate in SecondVC.viewWillDisappear or a method like that.
I'm working on an app that displays a today extension with some information. When I tap on the today extension, it opens the app and navigates to a subview from the root to display the information. Normally the user would then click the back arrow to go back to the main view, but there is no way to tell if this is actually done. It is possible for the user to go back to the today extension and tap again. When this is done, the subview is opened once again with new information. If this is done a bunch of times, I end up with a bunch of instances of the subview and I have to click the back button on each of them to get back to the main view.
My question: Is it possible to check if the subview is already visible? I'd like to be able to just send updated information to it, instead of having to display an entirely new view.
I am currently handling this by keeping the instance of the UIViewController at the top of my root. If it is not nil, then I just pass the information to it and redraw. If it is nil, then I call performSegue and create a new one.
I just think that there must be a better way of handling this.
Edit: Thanks to the commenter below, I came up with this code that seems to do what I need.
if let quoteView = self.navigationController?.topViewController as? ShowQuoteVC {
quoteView.updateQuoteInformation(usingQuote: QuoteService.instance.getQuote(byQuoteNumber: quote))
}
else {
performSegue(withIdentifier: "showQuote", sender: quote)
}
This is different from the suggested post where the answer is:
if (self.navigationController.topViewController == self) {
//the view is currently displayed
}
In this case, it didn't work because I when I come in to the app from the Today Extension, it goes to the root view controller. I needed to check whether a subview is being displayed, and self.navigationController.topViewcontroller == self will never work because I am not checking to see if the top view controller is the root view controller. The suggestions in this post are more applicable to what I am trying to accomplish.
u can use this extension to check for currently displayed through the UIApplication UIViewController:
extension UIApplication {
class func topViewController(base: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController? {
if let nav = base as? UINavigationController {
return topViewController(base: nav.visibleViewController)
}
if let tab = base as? UITabBarController {
if let selected = tab.selectedViewController {
return topViewController(base: selected)
}
}
if let presented = base?.presentedViewController {
return topViewController(base: presented)
}
return base
}
}
and usage example:
if let topController = UIApplication.topViewController() {
if !topController.isKind(of: MainViewController.self) { //MainViewController- the controller u wish to equal its type
// do action...
}
}
I've got a ViewControllerOne. ViewControllerOne is connected via Ctrl-Drag (in storyboard) to a menu-button mBtn (which means I don't know how it is implemented programmatically).
Clicking on this mBtn, a ViewOne appears (present modal). This ViewOne is bound to ViewControllerOne. ViewOne has a button btnOne.
Clicking on btnOne I want ViewOne to be dismissed and ViewTwo to be shown. ViewTwo belongs to ViewControllerTwo and to WindowControllerTwo.
The WindowControllerTwo-ViewControllerTwo-binding is the standard case as created on a new project.
I have the following code in the IBAction for button btnOne in ViewControllerOne:
#IBAction func onbtnOnePressed(sender: AnyObject){
let m_WindowControllerTwo = NSStoryboard(name: NSStoryboard.Name(rawValue: "Main"), bundle: nil).instantiateController(withIdentifier: NSStoryboard.SceneIdentifier("WindowControllerTwo")) as! NSWindowController // I have no custom class for the window controller as I don't really know what I can use it for ...
let m_ViewTwo = WindowControllerTwo.contentViewController as! ViewControllerTwo // my custom class for ViewTwo
m_ViewTwo.attributeIWantToPassToThisView = self.x // an attribute I want to pass from view a to view b
m_WindowControllerTwo.contentViewController = m_ViewTwo // passing the attribute from a to b
m_WindowControllerTwo.showWindow(self) // this does not work
self.dismiss(nil) // see NOTE
}
This code actually does not work. On debugging it step by step, I'm seeing the window/view flickering but not appearing...
NOTE: I could connect the button btnOne with a ctrl-drag to ViewControllerTwo. This works. But then the current ViewOne does not get dismissed!
Question: What am I doing wrong here? In iOS swift this also works. I don't quite get the WindowController stuff, so I'll need your advice on this.
Instead of this: m_WindowControllerTwo.showWindow(self)
use:
let application = NSApplication.shared()
application.runModal(for: wordCountWindow) //this will present WindowControllerTwo modally.
then to close your present controller add this line: PresentWindowControllerName.close()
So I have a UItextfield and a UIButton I was wondering if there is a way to save the text after the button is pressed in an instance variable so that I could use it in my other class.
The thing I am trying to do is to have a user input some text in the textfield on screen 1 and then when the user taps the button I want to take him to screen 2 however in the class of that screen 2 I want to know what text user entered in order to display data accordingly.
Right now I just have an action function for the button and I access text inside it and save it to an instance variable but when I call it in my other class it is empty because I initialized it as empty. So can somebody please help me and tell me how to go about this.
Thanks!
Here is the code for first screen
var searchRecipe = ""
#IBAction func SearchButton(sender: UIButton) {
if let recipe = RecipeSearchBar.text {
searchRecipe = recipe
}
}
Here is the code for second screen. I have connected the button in first screen this screen so when user taps the button he gets here.
var recipeName:[String] = []
var imageURL:[String] = []
var timeInSeconds:[Float] = []
func apiCall()
{
//search recipe API call
var searchRecipe = ""
searchRecipe = RecipesViewController().searchRecipe
print (searchRecipe) //prints nothing
endpoint = "http://api.yummly.com/v1/api/recipes?_app_id=apiId&_app_key=apiKey&q=\(searchRecipe)" //this is where I want to use the searchRecipe text from class 1
}
Well personally I would do what follows (Based on my interpretation of your issue):
Please note that I take for granted you are implementing a view-controller-based navigation and you know what IBOutlets, IBActions & Segues are
In the first view controller create an IBOutlet property of
UITextField named RecipeSearchBar and connect it to the relative text
field.
In the second view controller create a variable value of type
string;
Change the storyboard segue identifier to "toSecondViewController"
Then in the first view controller create an IBAction to be called
when the UIButton is pressed.
In your case:
#IBAction func SearchButton(sender: UIButton) {
if let recipe = RecipeSearchBar.text {
searchRecipe = recipe
}
//If you are navigating into a new view view controller
//here you need to call self.presentViewController(...)
}
Inside this action, you are going to call self.presentViewController
to display your second view controller, but you have to do one last
very important step: pass the value of the UITextField to the instance
that will hold the second view controller
To achieve this, override prepareForSegue in your first view controller
and share the UITextField value. This method is triggered once you called self.presentViewController for further implementation.
//Did not tested the code but should just be ok
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "toSecondViewController")
{
//Create the instance
let secondViewController = segue.destinationViewController
//Set the value
secondViewController.value = searchRecipe;
}
}
You are now good to go.
Hope this helped, if so mark the question for others.

I have a UIViewController with a UILabel that needs to display either "lbs" or "kg". My app has a settings screen (another UIViewController) that is presented modally over the first view controller and the user can select either of the two units and save their preference. If the units are changed and the modal settings screen is dismissed, I of course want the label on the first view controller to be updated with the new units value (but without refreshing the whole view). I thought I knew how to make it work, but evidently I don't.
On my modal settings screen, I have a UISegmentedControl to allow the user to select units. Anytime it's changed, this function updates userDefaults:
func saveUnitsSelection() {
if unitsControl.selectedSegmentIndex == 0 {
UserDefaultsManager.sharedInstance.preferredUnits = Units.pounds.rawValue
} else {
UserDefaultsManager.sharedInstance.preferredUnits = Units.kilograms.rawValue
}
}
Then they would likely dismiss the settings screen. So, I added this to viewDidLoad in my first view controller:
override func viewDidLoad() {
super.viewDidLoad()
let preferredUnits = UserDefaultsManager.sharedInstance.preferredUnits
units.text = preferredUnits
}
That didn't work, so I moved it to viewWillAppear() and that didn't work either. I did some research and some caveman debugging and found out that neither of those functions is called after the view has been loaded/presented the first time. It seems that viewWillAppear will be called a second time if I'm working within a hierarchy of UITableViewControllers managed by a UINavigationController, but isn't called when I dismiss my modal UIViewController to reveal the UIViewController underneath it.
Edit 1:
Here's the view hierarchy I'm working with:
I'm kinda stuck at this point and not sure what to try next.
Edit 2:
The user can tap a 'Done' button in the navigation bar and when they do, the dismissSettings() function dismisses the Settings view:
class SettingsViewController: UITableViewController {
let preferredUnits = UserDefaultsManager.sharedInstance.preferredUnits
// some other variables set here
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.topItem?.title = "Settings"
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Done", style: .Plain, target: self, action: #selector(self.dismissSettings(_:)))
if preferredUnits == Units.pounds.rawValue {
unitsControl.selectedSegmentIndex = 0
} else {
unitsControl.selectedSegmentIndex = 1
}
}
func dismissSettings(sender: AnyObject?) {
navigationController?.dismissViewControllerAnimated(true, completion: nil)
}
}
THE REAL PROBLEM
You misspelled viewWillAppear. You called it:
func viewWillAppear()
As far as Cocoa Touch is concerned, this is a random irrelevant function that hooks into nothing. You meant:
override func viewWillAppear(animated: Bool)
The full name of the first function is: "viewWillAppear"
The full name of the second function is: "viewWillAppear:animated"
Once you get used to this, the extreme method "overloading" that Cocoa Touch uses gets easier.
This is very different in other languages where you might at least get a warning.
The other lesson that everyone needs to learn when posting a question is: Include All Related Code!
Useful logging function I use instead of print or NSLog, to help find these things:
class Util {
static func log(message: String, sourceAbsolutePath: String = #file, line: Int = #line, function: String = #function, category: String = "General") {
let threadType = NSThread.currentThread().isMainThread ? "main" : "other"
let baseName = (NSURL(fileURLWithPath: sourceAbsolutePath).lastPathComponent! as NSString).stringByDeletingPathExtension ?? "UNKNOWN_FILE"
print("\(NSDate()) \(threadType) \(baseName) \(function)[\(line)]: \(message)")
}
