Adding a line break in a UITextView

Question

I have a UITextView that accepts an NSString with stringWithUTF8String formatting. It gets its values ​​from the database, and I want the text in the database to appear with gaps in the text. I tried using \n to do this, but it will display as text. Doing this on my application information page, as the direct text worked, but I think the reason it does not work when it is taken from the database due to formatting.

Any suggestions?

Answer 1

If you want to add a new line to the Xcode5 / Xcode6 storyboard Attribute-Inspector (AI), you will do this:

• Pull out a UITextView.
• Double-click it to edit the text, place the cursor where you want to break the paragraph.
• Press alt-Enter a couple of times to create an empty line and paragraph.

Or, CTRL + Return make a new line.

Now you can see the effect in the output / view mode in the storyboard.

Answer 2

Expand tc a bit: when you have newlines, you probably want to convert them to \n (that is, @"\\n" in Cocoa), then save them to the database and get the BACK string from the database, you probably want to convert them back to newlines. So you would use code 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"]; 

Answer 3

Just 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 displayed below in your text element or in any other place that you select

Exit:

January: 7, 21,

February: 4, 18,

March: 4th, 18th, etc. Etc.

Answer 4

I think you should try using "\ r".

I tested it on Xcode 4.2.1, iOS 4.3

Edit: this also works in iOS 3.0 and iOS 5.1

Answer 5

In Swift, just add "\ n" between the two lines

Example:

 let firstString = "Hello" let secondString = "Senorita" textview.text = firstString + "\n" + "secondString" 

Answer 6

UITextView will accept newlines, but it will not work with caries returns. You will need to make sure your entry is correct.

I tried it in IB editor, and at first had some problems with it. Then I used a text editor, typed the text and pasted it into the IB editor.

This is a trick for me. Your source comes from the database, so I think the newly-made lines are new lines, but carriage returns or something else. Check the HEX line of your input.

Answer 7

Set the keyboard type to (UIKeyboardType) and (UIReturnKeyTYpe) returnKeyType

if you are building code.

If you are using IB, just go to the first inspector panel and set TextInputTraits

Answer 8

when you receive from db. try

 NSString *content = [mytext stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"]; self.textView.text = content; 

Answer 9

if you get text from the internet, make sure you put a space before and after / n that solved my problem

as an example (php):

 echo $item_detail['item_title']." \n "; 

Answer 10

Olie answer extension ... In Swift, the code for updating a row from a database is:

 let dbString = // get the string from the db. myTextField.text = dbString.stringByReplacingOccurrencesOfString("\\\\n", withString: "\n") 

It took a while to figure it out, so I thought that I would share.

Answer 11

You save the literal "\ n" in the database. Try to save a new line.
