I'm using a SOAP service in my iPhone application and getting some text values from my remote database. In this text values, I intend to use \n for line breaks. But when I set the text of my UITextView to this value, it simply ignores the line breaks and shows them in single line.
If I declare its text in my code like myTextView.text = #"Break\me"; it works great. But when I call the text from service, it doesn't work.
How can I solve this?

I'm getting text from the MediaWiki API, and it includes getting \n text which indicates a new line. When I set the API results as the text of a WKInterfaceLabel, the \n's disappears, but no new line is created.
Any way to fix it?
Example. From this term:
[...] forms.\n\n==Use in writing systems==\n\n===English===\nIn Modern English [[English orthography|spelling]], {{angbr|i}} represents several different sounds, either the diphthong {{IPAc-en|aɪ}} ("long" {{angbr|i}}) as in ''kite'', the short [...]
It's meant to remove the \n's and replace it with new lines. What's added to the label is this text minus the \n's, but no new lines.
I want to add a line counter to a textfield for a sort of text editor. Looking around, I've seen that a lot of questions on this topic are either unanswered, or do not answer in a satisfactory manner. Something like this How to add prefix widget on every new line in textfield in flutter? asks fundamentally the same question I am, however the only answer there is to create a new widget for each line.
This is one method that could be used, where I add new textfields in a list and build them in a row with their respective line number. However, this means I cannot have those textfields function on more than one line, and I will need to add more textfields each time a user wants to add enough text to make it overflow. The biggest flaw I see with this, though, is that it makes it harder (if not impossible?) to easily select and edit text as you would expect from a text editor, such as using the built in systems for a textfield.
Now, for my solution I am using https://pub.dev/packages/extended_text_field as a way to gain some functionality that I don't really want to take the time to figure out how to do on my own (embedded onClick callbacks for text), so it would be ideal if I could continue to use that without having to fork or even have to figure out how to write my own version.
The primary issue I'm running into is not necessarily getting the number of lines, which can be found using some solutions from How can I add line numbers to TextField on Flutter?, but rather how and where to show those line numbers.
As above, it's not really ideal to pair some number alongside a textfield and create a new textfield for each expected line. What would be ideal, however, is something like , where each line number is prefixed to the line built by the text field. For example, like this: . Something like the solution proposed in Add a prefix to every line in a multiline Text Input in Flutter? would not work especially well, because the solution there is to literally add string values to the textfield, which would require systems to clean the text, in addition to causing an unexpected ability to actually change the numbers (or other line prefix) by the user.
So -- is there any way to implement a line prefix for each line in a textfield? Would it be possible to override an InputDecoration (which allows creating the individual line prefix, but nothing more) to create a line prefix for each line drawn by the textfield? If not, exactly what would be needed to create this? I am familiar with flutter, but I am not quite as familiar with the lower level API's.
Under certain circumstances, UILabel seems to bring an extra word to new line even when there is enough space for it, for example,
If one more word is appended,
Even if I force the width of the label to become something like below, it still moves the word consists of "c"s to the next line,
I've tried twisting the configuration of the UILabel, but seems it behaves the same unless I set the line breaking mode to character wrap, below is the configuration for the above cases,
And the constraints (in the first two cases, the trailing ),
Is there any reason for this particular behaviour and can I fix this? It looks weird in this way leaving that space emptied.
this is the default behavior since iOS 11, to fix orphaned words. No way to shut it off
to fix it
use the text as attributed text
or
use UItextview and turn of the scroll, edit option
or
use the custom label here
Get each line of text in a UILabel
You should set the line break to character wrap, because the letters after the space will be recognized as a word.
Hey I know this is late but I just figured out that you can cheat the system by adding a bunch of spaces at the end of the text.
If text of UILable may be changed, then it's still possible to use quick-dirty hack with "\n" - new line symbol.
Text "Aaaaaaaaaaaaaa bbb cccccccccc\ndddddd" will force UILabel to display:
Aaaaaaaaaaaaaa bbb cccccccccc
ddddddd
In Interface Builder new line can be inputted with Ctrl + Enter
If u use wordWrap, it tries to keep words in full form, as a result of this, it goes to next line. If you use character wrap, it will break on characters, and push the chars onto next line.
For Example:-
My name is ABCXXXX and I (have space here)
love myself.
Solution:-
Use NSMutableAttributedText and write love\n. It will make the "love" be in the space myself in the next line.
I'm trying to show some text on top of a plot. Using
text(13,15200,('~ 12h'),'HorizontalAlignment','right','VerticalAlignment','middle','FontSize',10,'FontAngle','italic');
I can create the text box how I want it. But a thing I didn't manage to do is to create a carriage return within that text object. Already tried to add '\r' or '\n' but the only thing I get is the display of '\r' or '\n' with out breaking the line. Any ideas?
And i now that text object are used to put text WITHIN axes. But I am still trying to find a way to put some text outside the grap. Searching stackoverflow I found this Post about using UICONTROL. It works great but when I export to EPS the text seems to be in pixel format and NOT vector - so it looks really bad. Is there another way besides using uicontrol??
Thanks a lot for help!
In text that is not interpreted, you can specify line breaks using the carriage return character, which has the ascii code 10.
text(x,y,sprintf('break after this%snew line here',char(10)));
To allow text outside axes, you need to turn off clipping for the text object
text(x,y,.....,'clipping','off')
I retrieve an NSString from a Property list and display it in a UILabel. The NSString already includes \n s, however the UILabel just displays them as text. How can I tell the UILabel to actually use the \n s as line breaks?
Everything you type into a plist in the plist editor is interpreted as plain text. Try it... put a ' into a field and right click -> view as "plain text" and you'll see it substitutes it for '. Therefore you can't put \n into a plist because it thinks you're just typing text and will treat it as such. Instead of putting \n into your plist use Alt+Enter to get your newline. If you view this as a text file now you'll see \ns printed and new lines acctually shown in the text file.
Now when you output it it won't display \n it will just give it a new line.
Plus, as has been mentioned UITextField is only one line anyway and you probably would benefit from using UITextView.
Well, first, you are going to need a string that you can modify. To accomplish that, you can simply do:
NSMutableString* correctedPath = [path mutableCopy];
At that point, you can use -insertString:atIndex: to insert any characters you need.
You're using the wrong class here.
UITextField doesn't (for all that I know) support multi-line input. For that, you will need a UITextView (it has editing enabled by default). It should interpret \n's without any problems. It also has a lineBreakMode property, if you want to make use of that.
