does anyone know how to make the voice over to read something that has no text using accessibility? for example, if you go on an image it reads a description, or if you go on a back button it would say back button.
I have tried the tooltip but that is not working and that is not what I'm looking for. thanks.
What you're looking for is the Semantics widget. For descriptions of the properties passed into the constructor of Semantics take a look at the SemanticsProperty class.

Setting showsTouchWhenHighlighted, e.g. via the IB option "Shows Touch On Highlight," on a button without a title will alter the VoiceOver description. After reading the accessibility label, VoiceOver beeps and announces a description of the image. Is there a way to disable this behavior?
Setting the accessibilityContainerType value to UIAccessibilityContainerTypeSemanticGroup works and that's great 👏 but I'm not sure that
this is the goal of this element.
Even if a button my be seen as a container, I understood this instance property dealt with
data-based containers rather. 🤔
I looked into your problem that arouse my curiosity and couldn't find out an appropriate solution with the Apple API unfortunately.
First, I thought that this solution may help but it didn't work as you mentioned in your comment... thanks. 😉
Apparently, when the showsTouchWhenHighlighted property is used, there's an added view inside the button that renders the glow touch ⟹ this is a UIButtonBarPressedIndicator image you can detect thanks to the Debug Hierarchy in Xcode for instance. 👍
This new image seems to put the default value of the accessibility trait property of your button image even if you have already changed it programmatically. 🤯
So, in order to avoid VoiceOver from using the screen recognition and reading out some useless information, I made something very ugly but efficient to reach your goal in the viewDidAppear for instance (see the 'basic operations' sheet of this link):
myButton.subviews.forEach{$0.accessibilityTraits = .none}
Bad hack due to a native problem of implementation or a simple line of code that anyone can understand, this solution removes every possible VoiceOver screen recognition from the button 🥳... and I'm still interested if you can explain a little bit the reason why your solution works, please. 😉
Set accessibilityContainerType = UIAccessibilityContainerTypeSemanticGroup.
I'm making an iPad app that lets me write swift code into a text box and save it to a document. It doesn't do any compilation or any complicated stuff like that, so I'm just looking for a way to format the code correctly in the text box (ex: code autocomplete, autoindent if possible, and maybe syntax highlighting). In short, I'd like my app's text field and keyboard to look similar to those of Swift Playgrounds.
If Apple's provided the code (or a built-in keyboard option that can do even some of this), I'd appreciate a link to it. Otherwise, how would I go about building a custom keyboard and text field (or at least disable the features like autocomplete that would get in the way)?
Thanks.
As far as I know the only way to do what you describe is to build a Swift Playgrounds app that presents a code editor window. Apple does provide documentation on creating third party iPad Swift playgrounds. I suggest looking it up on Apple's site.
What is the pop-up object used in the Apple's "Clock" app for iPad called?
The popup looks similar to a MapKit callout, but often comes out of the side of a clicked button. Apple uses the pop-up often to display pickerViews on iPad. I am wanting to use it also for iPad applications in Swift, but I cannot find the name anywhere in documentation or on StackOverflow--because I don't know what it is called and it is thus hard to find.
I already know that some may not like the simplicity of this question, but I have seriously tried and have looked through books and other documentation trying to identify what the name of it, but it is so hard to find it without knowing the name! (I've included an image of the object just to be clear, but, unfortunately, I don't have the 'reputation' for the image to show up automatically in StackOverflow)
Image: The Object/PopUp item used in the "Clock" App.
The object is a Popover, as identified by Dan.
Thank you those who contributed.
You must be talking about UIDatePicker.
We want a native rich text editor because we are trying to stay away from using Javascript and webviews for this solution.
We've tried many things so far, and we're left with quite a few obstacles that we just can't get around. Let me break it down into questions that I hope you can answer.
I have a UIButton, that says "B" on it, and I want to put it into the 'selected' state when a user sets 'Bold' from using the TextView's long-press gesture on a selection. How do I register for this state change? I tried adding an observer on the textView.attributedText, but it doesn't seem they are changing that dictionary, but instead are updating it. NSDictionary has no way, as far as I know, to add observers on the dictionary's keys. So I'm stuck with noticing this change.
Regarding number 1, I also tried setting the textView's inputDelegate and it seems that the method - (void)textDidChange:(id )textInput never gets called. :( Docs says is should. What did I do wrong?
How do I update the attributedText weight when I hit my bold italic or underline button.
How do I convert my attributed text into HTML?
I saw a few neat libraries for number 4, but I'm still curious what you'd come up with. (Broadens my options). But, I can't really work on number 4 until I figure out how to do the previous 3.
This editor will also need hyperlinks, bulleted lists, and numbered lists, more things I imagine I'll struggle through, but if you could answer the 4 questions above, that will keep me held over for a while. :)
Thanks!
Here is a link to an iOS rich text editor I've been working on.
https://github.com/aryaxt/iOS-Rich-Text-Editor
There is still a lot of work that has to be done, but the basic features are there.
The Apple sample application called 'TextEdit' does much of what you've described and, if not that, would be a very good starting point. Find the sample code with a search in the Organizer.
There is a commercial editor based on the DTCoreText library. I've used that library but not the rich text editor. Look at the Cocoanetics web site. It's not cheap but will save you a ton of work.
What most people mean by autocomplete is that the app has a textview/searchbar/whatever which accepts user input. Attached to this component is a tableview which keeps updating based on the user input. This is a well researched topic and is now relatively easy to implement thanks to the UISearchDisplay controller.
Now here is what I want. When the user is typing in some text in the UISearchBar, there will be no searchdisplaycontroller. Instead, I want the app to do something like Google Instant on desktops. That is, if I type "Goog", the searchbar should show Goog*le. So the suggestion "le" should be in a lighter font than the rest of the user input string Google. So I don't want an auto-suggest feature, I want an autocomplete feature.
Any ideas on how I can do this?
Thanks!
Alternatively, you can use this UITextField subclass (inspired by DOAutocompleteTextField):
https://github.com/hoteltonight/HTAutocompleteTextField
It's got a few more features and is actively developed. The example shows you how to use an array as the data source for the autosuggest text.
I haven't tried it but here's a control that appears to do what you're asking for:
