\n not working in UIlabel

I've seen similar questions here, but still can figure out why it's not working.

How to add line break (in other words add new paragraph) in multiline UIlabel?

I have a label with a lot of text,

lbl.numberOfLines = 0;
lbl.sizeToFit;

but I'm still getting something like this: "Some text here\nAnd here I want new line"

Thank you

This is old question but if any one want to do from interface builder.then it is easy and simple

select label and change type to attributed by default it is plain

enter image description here

now wherever you want to \n there just use Alt + Enter and you will get new line

hope it is helpful to someone who is using interface builder to achieve this

UILabel use \n to made new line. \n need a space in the back.

Your issue may be different... but mine was a literal character \n, which is actually \\n in memory.

I solved it with:

label.text = [rawText stringByReplacingOccurrencesOfString@"\\n" withString:@"\n"];

You still need to set line break mode as well as numberOfLines for it to work.

NSCharacterSet *charSet = NSCharacterSet.newlineCharacterSet;
NSString *formatted = [[unformatted componentsSeparatedByCharactersInSet:charSet] componentsJoinedByString:@"\n"];

This should work: 

lbl.lineBreakMode = NSLineBreakByWordWrapping;
lbl.numberOfLines = 0;

You can try this One :

lbl.text = @"My \n label";
lbl.numberofLines = 0;

This is an old question, but just wanted to let you know that \r works like a charm :)

I know it's old question, but i was wondering - could the problem be lbl.sizeToFit; ?

if you could set frame like CGRectMake(0,0,300,300) - does that solves the problem? Because \n works on my side.

actually there is a way to do that. try

    unichar chr[1] = {'\n'};
NSString *singleCR = [NSString stringWithCharacters:(const unichar *)chr length:1];
    [yourLabel setText:[NSString stringWithFormat:@"new%@line",singleCR]];

UILabel won't respect \n, You can use option-return (in Interface builder) to force where you want a line break.

You can use a UIWebView in place of the label and then you can format however you like. (And set the lineBreakMode as AngeDeLaMort says above.)

If your string is really ok, maybe you can try adding this line as well:

lbl.lineBreakMode = UILineBreakModeWordWrap;
