Answer 1

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

Answer 2

Just replace all occurrences of \n with empty string like this:

myString = [myString stringByReplacingOccurrencesOfString:@"\n" withString:@""];
