I am already able to add a layer with text in it using CATextLayer. However I'm finding the way the text is presented pretty basic. I would like to write paragraphs with quotes, in bold sometimes, italic etc...
Is there a way to do it with CATextLayer?
If not, how could I manage it, especially if the text is pulled out of a database?
I would like to be able to write the following text this way for instance:
"The article was about employment. He leafed through it in an instant. His feeling of anxiety resurfaced and he closed the magazine.
-Hm…, he breathed.
-Have you been looking for work long?, asked the stranger at his side."
Thanks
You dont need rich text if all you want to do is line breaks. add a \n for a newline. So:
layer.text=#"The article was about employment. He leafed through it in an instant. His feeling of anxiety resurfaced and he closed the magazine.\n\n-Hm…, he breathed.\n\n-Have you been looking for work long?, asked the stranger at his side."
Real Rich Text isn't possible AFAIK

Regarding the spell checking in iOS, it's possible to tell the checker to ignore a word (or learn a word),
https://developer.apple.com/documentation/uikit/uitextchecker
func ignoreWord(String)
Tells the receiver to ignore the specified word when spell-checking.
- Apple doco
Say I have a UITextView which opens. I want spell checking On.
I know the user may type "fattie" which would get the red underline.
How do I tell that text view in that instance, to, ignore "fattie" ?
An obvious use case ...
User is typing in "#tag" type friends; in our data of course we know what all the tags are, it's absurd they get marked as spelling errors.
It seems incredible one can't just say "don't underline these words - - list".
Code example ....
So we have
var t: UITextView
and then, there must be "some way" to:
yourTextView.something->something.textChecker.ignoreWord("fattie"
.. some way to get to the text view's textChecker instance! How ?!?!
Partial answer: I just stumbled on to that, bizarrely, you can just call
UITextChecker.learnWord("fattie")
UITextChecker.learnWord("blahdee")
from, apparently, just anywhere in an app.
However this raises many issues,
• How to call the 'ignore' one, which seems better
• That one still makes the user tap the annoying, stupid, "in quotes" OK box in the suggestions bar - it seems to have not really "learned" anything
• Disturbingly, I think this goes for the "WHOLE PHONE". I only want it in that instance of the user using that text view.
A mystery!
When I am copy-pasting method name from Blackfire profile, I am getting a reversed string like this:
sgnitsiLredivorPdaol::yrotisopeRresopmoC\yrotisopeR\resopmoC
What is intended way to copy a proper method name (not reversed)?
Why does Blackfire has such behaviour? Is this some kind of stupid joke or copy-paste protection?
This is indeed a UX issue we currently have in Blackfire, let me explain it to you:
We want to display the end of the namespace/classname value in this part of the interface
We want to have a text-overflow ellipsis on the left part of the value.
Unfortunately, using text-overflow: ellipsis on the left of the text is not supported by modern browsers at the moment.
There are two ways to do that: Either know the width of the text, work with a fixed width column and truncate programmatically or use a hack, revert the letters, change the text direction from left-to-right to right-to-left locally and use traditional text-overflow.
As we deal with a resizable UI here, we chose the second option, and this is the one that provide the better experience at the moment. However, as you notice, this issue remains.
We're thinking about a fix for this issue. It might be with the Clipboard API.
In the meantime, here's the way you can copy/paste the value :
Just expand a node and copy from the inner box, see:
Hope it helps you until we find a better solution.
I'm making a custom keyboard for lawyers, and trying to load law related words in suggestion/prediction bar on top the keyboard based on what user types. Just like in stock keyboard. I have searched around but did not find any concrete answer.
I want to display suggestions of law related terms that I have in a txt file, all words are sorted alphabetically.
DEMO
Here is what I have tried:
UILexicon
let myLexicon = NSMutableDictionary()
self.requestSupplementaryLexiconWithCompletion { (theLexicon: UILexicon!) -> Void in
let lexiconEntries = theLexicon.entries
// Completion handler
for item in lexiconEntries {
self.myLexicon.setObject(item.documentText, forKey: item.userInput)
}
}
This code just gives 23 nil objects.
UITextChecker This is an iOS class that is designed to spot spelling errors, which makes it perfect for knowing if a given word is real or not. This is seems to be mainly for autocorrection, not for suggestion. Correct me if I'm wrong please.
I cannot somehow make sense out of these two classes.
How do I tell custom keyboard, "Hey if user enters "V" show the top 3 words that start from V, then if user enter a, fill the suggestion bar with words that start with "Va" and so on.
EDIT: Looks like someone ran into same problem. Here is a quote how they solved it, I will update with code once I finish figuring this out myself.
However, this was far from the truth - in fact, Apple do not allow access to their dictionary full stop, only offering a UILexicon class instead as stated in their docs:
Make use of this class, along with a lexicon of your own design, to provide suggestions and autocorrections as users are entering text.
As it turns out, the UILexicon class only really contains contact names along with any shortcuts (like the default On My Way!) defined on the device. So before writing the logic for a keyboard, you first have to implement your own autocorrect library.
We browsed through a few external projects to see if we could include them in the keyboard - most notably Hunspell, which is used by OpenOffice, and Presage, an intelligent predictive text library.
I spent a long time integrating the C++ libraries with the code, but in the end, in order to keep complexity down, we opted to use a combination of UITextChecker (which provides some basic corrections) and our own custom dictionary, containing a few commonly mispelled words.

Thanks!
You have to implement your own autocorrection system. UILexicon will only give you shortcuts the user has set up, words that they have added to the iOS Dictionary, and names of contacts. It has no awareness of any words that you yourself provide, whether in a txt file or in any other form.
If you want to use the TOMSSuggestionBar, it appears from the sample code that the onus is on you to convert your txt file into a core data model, and indicate to the suggestion bar how it is to interpret the contents of that model. You may also want to implement the data source protocol to get more fine grained control over the suggestions.
Autocorrection and next word prediction are not solved problems; I suggest you do your own research and find the solution that is best suited to your goals.
I use LibreOffice Writer and I want to insert an alternative text to a specific phrase in the document, how can I do it?
Example if we have an image in the document we can make double left click and add the alternative text like this:
Is it possible to make the same if we select a whole phrase of text? If yes how? And if No is there any other proposal?
The alternative text in 'word'/odt documents is actually intended as the 'alt' attribute in HTML (web) pages:
The alt attribute provides alternative information for an image if a
user for some reason cannot view it (because of slow connection, an
error in the src attribute, or if the user uses a screen reader).
(http://www.w3schools.com/tags/att_img_alt.asp)
It's only purpuse is thus to provide the user with information in case he/she can not view the image. Since having alternative text in case some text cannot be displayed is, well, silly, this 'alt' attribute is not defined for pieces of text. Alternatively, you could have a hyperlink pointing to nothing ("#"), which does provide a tooltip attribute.
What is it that you're intending to achieve anyway? It's not going to show up on any prints, which is the intended purpose of Writer... Footnotes (for prints) or Comments (for communication with co-editors) might suit you better.
I am building a simple invoice application, and I would like to allow the users to customize the text on the invoice. In addition to this, they should be able to reference specific attributes in my models, i.e. "This is a test {{Model.attribute}}", and once the text is parsed the tag is replaced with the value of that attribute.
I have looked a bit at redcloth, textile and handlebars, but it does look like a little bit overkill to be honest. For instance I would not like to allow the users to input any HTML.
I would really appreciate if someone could point me in the right direction. There is probably a gem for this that I just havent found yet.
Thanks in advance
I use liquid with simpleformat which will sanitise the text.
