    For logging using "NSLog", the newline, carriage return is added for you automatically..

    The vbCrLf command basically adds a Carriage Return, and Line Feed..

    What are you trying to do?

    A carriage return is accomplished by using \r and a line break is \n.

    You put \r and \n within the confines of your string. So, a string might look like the following:
    Code:
    NSString *myString = @"My String\n";
    That would produce:
    Code:
    My String
    <new line>

    To concatenate two strings, you have a couple of options. One is to use to use a NSMutableString, and the other is to string with the NSString, but create a new one..

    So for example..
    Code:
    NSString *first = @"Hello ";
    NSString *second = @"World";
    
    NSString *result = @"";
    result = [result stringByAppendingString:first];
    result = [result stringByAppendingString:second];
    The NSString result now contains "Hello World" in it..

    The second option is
    Code:
    NSString *second = @"World";
    NSMutableString *result = @"Hello ";
    
    result = [result appendString:first];
    The NSMutableString result now contains "Hello World".

    You might want to read up on Mutable and Immutable objects and see the pros and cons about using one over the other..
