Currently i have an issue in editingDidEnd method of swift textfield.
I have a module inside editingDidEnd func to check some validation in B ViewController. If the validation is wrong then it shows popup / alert.
In this case, while user is typing and still focus on the textField, users tap back on navigation bar. it makes editingDidEnd function is also called. So the page is showing A ViewController and also showing pop up.
Is there any workaround to handle this issue? I don't want the alert is showing when i tap back in navigation bar. My expectation is if user press back on navigation. it's not call editingDidEnd function
Thanks Before
e.g.
B View Controller
extension bviewcontroller: textfielddelegate {
func editingDidEnd(_ value: String, textField: SearchTextField) {
//showingalert
}
}
You can add a guard statement to your editingDidEnd method like below.
func editingDidEnd(_ value: String, textField: SearchTextField) {
guard navigationController?.topViewController is bviewcontroller else {
print("DON'T SHOW ALERT")
return
}
print("SHOW ALERT")
}
I have tested the above code with a simple view controller containing a UITextField. However, your delegate method appears to be something different than the standard UITextFieldDelegate's textFieldDidEndEditing(_:) method.
Otherwise I would have suggested that you could also try experimenting with the textFieldDidEndEditing(_:reason:) method.
This seems like maybe a simple question, but I'm looking for a way to make one (or more, I suppose) buttons in an ActionSheet in SwiftUI to be disabled. For example, if something is illegal based on the state of the app, I don't want to let the user click the button - indeed, I might change the text to explain why it's disabled.
Xcode autocomplete isn't really turning anything up for me, and the docs (here and here) aren't giving me anything. Is my best/only option simply not putting the button in the list of buttons in the ActionSheet? (And kinda letting the user infer why it's not there...)
Thanks so much for any advice!
My simple code:
private func getActionSheet() -> ActionSheet {
let buttons: [ActionSheet.Button] = [
.default(Text("This is fine...")) { foo() },
.default(Text("This is forbidden - disable me!")) { foo() },
.cancel()
]
return ActionSheet(title: Text("Do it!"), buttons: buttons)
}
For nondestructive actions you can simply show a Menu. They support the .disabled(true) modifier.
var body: some View {
Menu("Do it!") {
Button("This button works fine", action: { })
Button("This one is disabled", action: { })
.disabled(true)
}
}
When I used third party SCLAlertView there was a problem actually there is a problem that is I want to perform some action when the button will pressed but there is just the customization properties but I am wondering for the action scope can someone help me out?
you can use this
let appearance = SCLAlertView.SCLAppearance(
showCloseButton: false // if you dont want the close button use false
)
let alertView = SCLAlertView(appearance: appearance)
alertView.addButton("Ok Pressed") {
print("Ok button tapped")
}
alertView.showSuccess("Success", subTitle: "")
you get the detail example for add buttons and hide default close buttons property in SCLAlertView
I never used this library, however if we take a look at the Github repo of the project (https://github.com/vikmeup/SCLAlertView-Swift) we will see the following example:
alert.addButton("Show Name") {
print("Text value: \(txt.text)")
}
Where print("Text value: \(txt.text)") gets executed after clicking the button.
all this is probably a trivial question, but I have not found a solution to it. I am making an app for Iphone using Swift.
I have a tableview with some strings and if I press a button I want to navigate back to the previous view directly. However, the code after my call
navigationController?.popViewControllerAnimated(true)
is always run, but I want the current activity to stop and go back to the previous view.
The code looks like:
#IBAction func DeletePressed(sender: UIButton) {
let deleteIndices = getIndexToDelete()
navigationController?.popViewControllerAnimated(true)
print("After navigationController")
for index in deleteIndices{
results?.ListResults[yearShownIndex].months[monthShownIndex].day[dayShownIndex].results.removeAtIndex(index)
}
if (results?.ListResults[yearShownIndex].months[monthShownIndex].day[dayShownIndex].results.count == 0){
results?.ListResults[yearShownIndex].months[monthShownIndex].day.removeAtIndex(dayShownIndex)
}
if (results?.ListResults[yearShownIndex].months[monthShownIndex].day.count == 0){
results?.ListResults[yearShownIndex].months.removeAtIndex(monthShownIndex)
}
if (results?.ListResults[yearShownIndex].months.count == 0){
results?.ListResults.removeAtIndex(monthShownIndex)
}
loadView()
}
"After navigationController" is always displayed.
In android you would start a new activity by creating intents to get the desired behaviour, but how does it work on Iphone?
My problem is that I want to be able to go back directly when navigationController.popViewControllerAnimated is called. This is just a toy example to understand how it works so that I can use it in the if-clauses later.
you could simply add a return statement after you pop the viewcontroller:
#IBAction func DeletePressed(sender: UIButton) {
let deleteIndices = getIndexToDelete()
navigationController?.popViewControllerAnimated(true)
return;
[...]
if you don't wants to execute code after "print("After navigationController")" then remove that code
or it is not possible to remove then toggle it when DeletePressed called
I just started with UI testing in Xcode 7 and hit this problem:
I need to enter text into a textfield and then click a button. Unfortunately this button is hidden behind the keyboard which appeared while entering text into the textfield. Xcode is trying to scroll to make it visible but my view isn't scrollable so it fails.
My current solution is this:
let textField = app.textFields["placeholder"]
textField.tap()
textField.typeText("my text")
app.childrenMatchingType(.Window).elementBoundByIndex(0).tap() // hide keyboard
app.buttons["hidden button"].tap()
I can do this because my ViewController is intercepting touches:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
view.endEditing(false)
super.touchesBegan(touches, withEvent: event)
}
I am not really happy about my solution, is there any other way how to hide the keyboard during UI testing?
If you have set up your text fields to resign FirstResponder (either via textField.resignFirstResponder() or self.view.endEditing(true)) in the textFieldShouldReturn() delegate method, then
textField.typeText("\n")
will do it.
Swift 5 helper function
func dismissKeyboardIfPresent() {
if app.keyboards.element(boundBy: 0).exists {
if UIDevice.current.userInterfaceIdiom == .pad {
app.keyboards.buttons["Hide keyboard"].tap()
} else {
app.toolbars.buttons["Done"].tap()
}
}
}
Based on a question to Joe's blog, I have an issue in which after a few runs on simulator the keyboards fails to hide using this piece of code:
XCUIApplication().keyboard.buttons["Hide keyboard"]
So, I changed it to: (thanks Joe)
XCUIApplication().keyboard.buttons["Hide keyboard"]
let firstKey = XCUIApplication().keys.elementBoundByIndex(0)
if firstKey.exists {
app.typeText("\n")
}
What I try to do here is detecting if the keyboard stills open after tap the hide button, if it is up, I type a "\n", which in my case closes the keyboard too.
This also happens to be tricky, because sometimes the simulator lost the focus of the keyboard typing and this might make the test fail, but in my experience the failure rate is lower than the other approaches I've taken.
I hope this can help.
I always use this to programmatically hide the keyboard in Swift UITesting:
XCUIApplication().keyboards.buttons["Hide keyboard"].tap()
XCUIApplication().toolbars.buttons["Done"].tap()
With Swift 4.2, you can accomplish this now with the following snippet:
let app = XCUIApplication()
if app.keys.element(boundBy: 0).exists {
app.typeText("\n")
}
The answer to your question lies not in your test code but in your app code. If a user cannot enter text using the on-screen software keyboard and then tap on the button, you should either make the test dismiss the keyboard (as a user would have to, in order to tap on the button) or make the view scrollable.
Just make sure that the keyboard is turned off in the simulator before running the tests.

Then enter your text using the paste board
textField.tap()
UIPasteboard.generalPasteboard().string = "Some text"
textField.doubleTap()
app.menuItems["paste"].tap()
I prefer to search for multiple elements that are possibly visible to tap, or continue, or whatever you want to call it. And choose the right one.
class ElementTapHelper {
///Possible elements to search for.
var elements:[XCUIElement] = []
///Possible keyboard element.
var keyboardElement:XCUIElement?
init(elements:[XCUIElement], keyboardElement:XCUIElement? = nil) {
self.elements = elements
self.keyboardElement = keyboardElement
}
func tap() {
let keyboard = XCUIApplication().keyboards.firstMatch
if let key = keyboardElement, keyboard.exists {
let frame = keyboard.frame
if frame != CGRect.zero {
key.forceTap()
return
}
}
for el in elements {
if el.exists && el.isHittable {
el.forceTap()
return
}
}
}
}
extension XCUIElement {
///If the element isn't hittable, try and use coordinate instead.
func forceTap() {
if self.isHittable {
self.tap()
return
}
//if element isn't reporting hittable, grab it's coordinate and tap it.
coordinate(withNormalizedOffset: CGVector(dx:0, dy:0)).tap()
}
}
It works well for me. This is how I would usually use it:
let next1 = XCUIApplication().buttons["Next"]
let keyboardNext = XCUIApplication().keyboards.firstMatch.buttons["Next"]
ElementTapHelper(elements: [next1], keyboardElement: keyboardNext).tap()
Nice thing about this is you can provide multiple elements that could be tapped, and it searches for keyboard element first.
Another benefit of this is if you are testing on real devices the keyboard opens by default. So why not just press the keyboard button?
I only use this helper when there are multiple buttons that do the same thing, and some may be hidden etc.
If you are using IQKeyboardManager you can easily do this:
app.toolbars.buttons["Done"].tap()
This way you capture the "Done" button in the keyboard toolbar and hide the keyboard. It also works for different localizations.
