How do I remove new line characters from a string?

I need to strip away any new line characters from a string. I tried the stringByReplacingOccurencesOfString method below. What is the correct method to do this in Objective C?

[textLine stringByReplacingOccurrencesOfString:@"\n" withString:@""];

stringByReplacingOccurrencesOfString does not modify textLine

NSString *strippedTextLine = [textLine stringByReplacingOccurrencesOfString:@"\n" withString:@""];

Or

NSString *textLine = @"My cool text\n";
textLine = [textLine stringByReplacingOccurrencesOfString:@"\n" withString:@""];
