Adding a line break to a UITextView
Utf 8NsstringUitextviewWhitespaceUtf 8 Problem Overview
I have a UITextView that takes an NSString with formatting stringWithUTF8String. It is getting its values from a database and I want the text in the database to be rendered with breaks within the text. I tried using \n to do this but it gets rendered as text. Doing this in my information page of the app as straight text worked but I think the reason its not working when taking it from the database is because of the formatting.
Any suggestions?
Utf 8 Solutions
Solution 1 - Utf 8
If you want to add newline in Xcode5 / Xcode6 storyboard Attribute-Inspector (AI), you do it this way:
- Drag out a UITextView.
- Double-click it to edit text, place cursor where you want the paragraph break.
- Hit alt-Enter a couple of times to create a blank line & paragraph.
Or, CTRL + Return make a new line.
You can now see the effect into output / View-mode in storyboard.

Expanding tc's answer a bit: when you have newlines in the string, you probably want to convert them to \n (that is, @"\\n" in Cocoa) then save to the database and, on getting the string BACK from the database, you probably want to convert those back to newlines. So you'd use code something like this:
NSString *saveString = [myTextField.text stringByReplacingOccurrencesOfString: @"\n" withString: @"\\n"];
// save it to the db
// ... later ...
NSString *dbString = // get the string from the db.
myTextField.text = [dbString stringByReplacingOccurrencesOfString: @"\\n" withString: @"\n"];
Solution 3 - Utf 8
Simply the below:
{
textView.text = @"January: 7th,21st,\n February: 4th,18th,\n March: 4th,18th,\n April: 1st, 15th, 29th, \n May: 13th, 27th, \n June: 10th,24th, \n July: 8th, 22nd, \n August: 5th, 19th, \n September: 2nd, 16th, 30th, \n October: 14th, 28th, \n November: 11th, 25th";
NSLog (@"Recycle Dates for Abbey Way");
}
will be out putted as below in your textView or whatever you choose
Output :
January: 7th, 21st,
February: 4th, 18th,
March: 4th, 18th etc etc
Solution 4 - Utf 8
In Swift, just add "\n" between two strings
Example:
let firstString = "Hello"
let secondString = "Senorita"
textview.text = firstString + "\n" + "secondString"
Solution 5 - Utf 8
I think, you should try using "\r".
I have tested it on Xcode 4.2.1, iOS 4.3
Edit: This also works in iOS 3.0 and iOS 5.1
Solution 6 - Utf 8
A UITextView will take the newlines, but it will not work with cariage returns. You will have to make sure your input is correct.
I tried it in the IB editor, and had some troubles with it initially. Then I used a text editor, typed my text and then pasted it into the IB editor.
That did the trick, for me. Your source comes from a database, so I think probaly the newlines are actually newlines, but perhaphs carriage return's or other. Check the HEX string of your input.
Solution 7 - Utf 8
when you get from db. try
NSString *content = [mytext stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];
self.textView.text = content;
Solution 8 - Utf 8
Set the (UIKeyboardType)keyboardType and (UIReturnKeyTYpe) returnKeyType
if you are building in code.
If you are using IB then just go to the first inspector panel and set the TextInputTraits
Solution 9 - Utf 8
if you are getting the text from web, make sure you put a space before and after the /n that solved my problem
as example (php):
echo $item_detail['item_title']." \n ";
Solution 10 - Utf 8
Append a character("\n") in the string
var logs = "this is first Line"
self.logs.append(Character("\n"))
self.textView.text = self.logs
Solution 11 - Utf 8
Expanding on Olie's answer... In Swift the code for updating the string from the database is:
let dbString = // get the string from the db.
myTextField.text = dbString.stringByReplacingOccurrencesOfString("\\\\n", withString: "\n")
Took me a while to figure out, so thought I would share.
Solution 12 - Utf 8
You're saving a literal "\n" in the database. Try saving a newline.
