    Hello, i believe the NSLog statement starts a new line each time it is used(like \n) . is there a way to prevent this? i.e. so multiple print statements appear back to back?

    p.s. i don't just mean comma delimited either.

    I'm pretty sure there's no way to do that.

    You can use printf() or the related functions for this.

    Also, you can build up a single string with all the text that you want and then print it in a single call to NSLog.

    NSLog

    Yes, i was thinking of combining strings using append....
    Basically , i would like to neatly print playing card descriptions across the screen in columns of threes and left justified

    Ace of clubs 4 of diamonds 6 of hearts
    5 of diamonds

    and so on...

    i have tried using something like
    NSLog(@"%-15s",[[tempCard CardDesc ] UTF8String]);

    but i would like to link these together in threes, plus i don't really understand the syntax of these special strings???

    By screen I guess you mean the debugger console.

    I use printf quite a bit for this kind of logging because it doesn't end up the system console, unlike NSLog. I really don't need this kind of debugging info filling up my system console.
