How to insert new line \n from UILabel text which typed in IB?

Question

I have id textInput and I insert new line(\n) OK with:

[textInput insertText:@"\n"];

But when input Text from label.text (Input in Interface Builder) ,it NOT OK. Just input \n text.

NSLog(@"%@",label.text);
[textInput insertText:label.text];

How to input special character when store it in label.text?

I don't want to compare [inputStr isEqualToString:@"\\n"];

*Log: \n

Thanks!

I put \n to label and [textInput insertText:label.text], NOT Work, just get \n text. Nothing wrong here. — Alex, Mar 16 '13 at 02:47
Hint: If you NSLog the data and it prints "\n" then it doesn't contain "\n". — Hot Licks, Mar 16 '13 at 02:53
They are the same. You're doing something wrong. (And you're not showing us your real code.) — Hot Licks, Mar 16 '13 at 03:00
I've edit, please check! Something wrong when input text from UILabel.text. Thanks! — Alex, Mar 16 '13 at 03:02
Your problem is that label.text doesn't contain the newline code represented by "\n" but instead contains the characters "\" and "n". This could presumably happen if you put "\n" into the text field of a label in Interface Builder, but if you code the C string "\n" or the Objective-C NSString @"\n" that combo will always be converted to newline. — Hot Licks, Mar 16 '13 at 03:07
Don't input your text with IB. No need to. Or, if you insist, translate the characters afterwards. replaceOccurrencesOfStringWithString, IIRC. — Hot Licks, Mar 16 '13 at 03:15

Try option-return or pasting in the newline.

The best way :D :thumbsup: – Ankit Kumar Gupta Apr 21 '17 at 09:59
For some reason, ctrl+return works, but option+ret doesn't. – void Nov 14 '18 at 06:06
number of lines should be 0 – Noshaid Ali Sep 25 '19 at 09:14

@Hot Licks explained the reason well in comment.

The only way is

if ([self.mylabel.text isEqualToString:@"\\n"]) {

   [self.myTextView insertText:@"\n"];
}

Manually, use ALT+ENTER

Please see my edit. Do you know the reason why? – Alex Mar 16 '13 at 02:58
Sorry! Not work. Could you please do a test? – Alex Mar 16 '13 at 03:06
Thanks @Ramshad! I test this case before, but I have some special chars typed in IB, so that I don't want to compare all cases. I'm waiting! – Alex Mar 16 '13 at 03:30
Found \r in another answer and it works fine :-) – JanB Jan 20 '15 at 15:13
