I want to display a calculated result that can be copied to pasted elsewhere (e.g., another app), but that can not be edited/modified. I would also like to indicate if that result has more character than fit in the view.
Is it better to use a UILabel, UIButton, UITextField, or UITextView?
So far, the only one I've found to work is the UITextView by setting:
textView.isEditable = false
textView.isEditable.isUserInteractionEnabled = true
However, as an example, the view initially appears like this:
, which seems to indicate that the result is 8,872,750 - there is no indication that there may be more digits.
In fact, the actual result is 8,872,750,000,000,000,000,000.
If I double-click on the textview, I get:
and can copy the contents.
Clicking elsewhere then back in the textview, I get:
. While I can scroll by dragging the cursor up or down, I can not if using up or down arrows.
On the other hand, a UITextField shows like this: . The contents may be copied - but they may also be modified or deleted.
How do I display a result that may be copied, may not be modified, and gives some indication if the value extends beyond the view?
I suggest using a UITextView with isSelectable set to true and isEditable set to false.
A text view can be set up to add a scroll bar if desired.

In my application (that has to be accessible for blind user) I have this scenario (its a grammatic exercise)
When I try it on a device turning on VoiceOver, first it focus on the first part of the sentence, so in that case it read "Kesha" and when i swipe right to read the next part it read the second part of the sentence "the contract because...". What I want is to make it also focus on the gray box (that is a UIViewelement) before it read the second part of the sentence, so that the user know where that empty box is in the sentence, but i don't know how to do that.
I alread tried grayBox.accessibilityLabel = "empty box" or grayBox.accessibilityHint = "empty box" but it just don't set the focus on that view and it doesn't speak. I also tried to put an empty UILabel inside the box but I have some issue positioning that in the right order and I don't think it is the right way to do it. Any suggestion?
On the UIView that you want to 'receive focus' you just need to enable accessibility or mark it as an accessible element, An example:
myGreyView.isAccessibilityElement = true
myGreyView.accessibilityLabel = "A grey box"
myGreyView.accessibilityHint = "this is a secretive box. I don't know what it does"
You can also tick a box in the UIView's properties in xcode interface builder "Accessibility Enabled" I think its called. Which also lets you set the label and hint.
For more information see this Apple guide to VoiceOver
In regards to the order of elements being read out. Is the first part and second part different UILabels or one label?
Are you adding these in code or Xib/Storyboard? Depending on the order they are added as subviews can effect the order VoiceOver reads items out.
When adding the 3x UI elements add them in this order below.
UILabel - "Kesha"
UIView - Gray box, "A grey box"
UILabel - "the contract because it was not fair."
If you have added them via Interface builder (Xib/Storyboard) make sure the order is correct in the view hierarchy.
If this fails you could try overriding the method "accessibilityElements" and return an array of the labels and grey view in the order you want them read out.
I wanted a floating label text filed with underline or baseline for one of my iOS apps. I found that I can achieve that by making use of JVFloatLabeledTextField. So I drag & dropped some text fields to my storyboard and assigned JVFloatLabeledTextField as a class(custom) to those fields so that these text fields will be of type JVFloatLabeledTextField.
ISSUE1
In the below image the first part is what is showed after running the app. The issue here is when I start typing text in any of the textFields the place holder should animate upward but in my case the place holder is not showed/disappears as shown in the 2nd part of below image.When we tap on any other textField then the previously used textField palce holder is showed as shown in 3rd part of below image.
ISSUE2
keepBaseline = true, I have given this property to get the underline/baseline for the textFields, which I'm not getting.
I'm keeping all these text Fields in a stack view, will that cause any issue?
Programatically I haven't written any code for this.

I'm trying to accomplish an autocomplete of my own for matching array items while typing. So, I already have the logic done for matching what's being typed with what's in the array, but my question is related to displaying the proposed correction in the UITextView like this screenshot
I was trying by splitting the text in the textview and replacing the last word into attributed strings, but that makes the proposed correction part of the actual contents. Any ideas of how this is accomplished in this app?
What you currently do is good , when you set the text of the textView to attributed string make bool flag say it's name is textEdited = true with a string part that the user types say it's name userStr , when textView change method is triggered check that bool and according to it make the search if it's true proceed search with userStr if it's not proceed search with whole textView text , don't forget to make textEdited= false after every zero suggested result
Edit: regarding the cursor put a label under the textfield with the same font as the textView and make it's background darkGray , also make background of the textview transparent and every attributed string assign it to the label so plus part of the label will be shown and cursor will be as it is in the textView
This is a little hard to explain so please bear with me. When I am editing a text field in one of the columns I would like to,when I hit enter, go to new line under the edited text so the grid basically expands.
Options-View-CellAutoHeight set to true expands the cell but editing is terrible.Cant
see a thing where the first line is,where it ends,etc...
Here is the grid:
I can not go after the last letter 'a' with my mouse cursor and hit enter so another line gets added. Which settings regulate this ? I know it can be done since I had a grid once and could do this.
EDIT: This requires no code just applied settings.
Just tested it with DevExpress VCL 13.2 and it can be easily done without coding (if I understood what you want to achieve).
Basically, you need to set following properties:
Assign a Memo to the Properties of your column and make sure its WantReturns property is set to true.
In your TableView set the OptionsView.CellAutoHeight property to true.
Also in your TableView, set the OptionsBehavior.EditAutoHeight to either eahEditor (editor is sized vertically to fit the content) or eahRow (the entire row is sized when editing) as needed.
Is it possible to add a text link into a TextView? I want the link to perhaps behave like a button, where I can assign an action to it.
EDIT: When I say assign an action, I mean actually giving it something in the code. I'm wondering if it's possible to dynamically add a "button" into text that I can assign a coded action to.
Live scenario
Think of something like a dictionary app. Maybe the definition of one word uses another word that you might not know the definition of, so being able to click on that word to instantly search it rather than having to type it in would be a nice user friendly feature. It seems rather unlikely, though, I guess.
I would recommend using NIAttributedLabel from Nimbus, an open source iOS library. You can specify text ranges that are links, and you get delegate messages sent when a user taps on it.
Main Nimbus site: http://nimbuskit.info/
NIAttributedLabel docs: http://docs.nimbuskit.info/interface_n_i_attributed_label.html
in the inspector, go to the Text View Attributes tab then make sure "Detect Links" is checked.
Yes you can. Add the URL into the text view, then open up the Attributes Inspector. You will see an option in there to detect links.
I know of a way, but its a LOT of work. First, you have an NSAttributedString that you have the text view display. Second, attribute the range of text you want to be the button. Third, assign a tap gesture recognizer to the text view and in the method called by the recognizer, you'll use core text to determine if the tap happened over the range of text that represents the buttons.
Heres how youll use core text: create a framesetter with the attributed string. Create a frame from the framsetter with the shape of a square that is the frame of the text view, inset by the padding of the text view. The frame will allow you to get the y origins of every line in the text view and and once you know what line the tap happened on, you can use the line to then figure out exactly what character was tapped on that line by giving it an x offset. Once you know character index on the line, you can add it to the beginning of the range of the line and get the index of the character within the whole string. Then you can check if its within the range of the text that is your button. If it is, you can then call a method to simulate a target action type behavior.
Ive explained the process of how to accomplish this and specified what kinds of core text objects youll need, ill let you look up the specific api details:
