Just do it like this :)
NSString * strCheck = @"A\nB"; strCheck = [strCheck stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"]; //This is to prevent for fetching string from plist or data structure label.numberOfLines = 0; label.lineBreakMode = NSLineBreakByWordWrapping; label.text = strCheck;
