Macros for Xcode

These are some of the macros I use with Xcode:

CMLog: I use this macro to replace NSLog:

#define CMLog(format, ...) NSLog(@"%s:%@", __PRETTY_FUNCTION__,[NSString stringWithFormat:format, ## __VA_ARGS__]);

CMLog(@"My iPhone is an %@, v %@", [[UIDevice currentDevice] model], [[UIDevice currentDevice] systemVersion]);

you get this in the console:

HowTo fit text inside a UIWebView

If, like me, you want to make sure your text will fit inside your UIWebView (without scrolling), you can implement the following javascript:

    <script language='javascript' type="text/javascript">
    function adjustHeight(maxHeight) {
      elem = document.getElementById("sign");
      height = elem.offsetHeight;
      current_size ='px','')/1;
      while ((current_size-- > 10) && (height > maxHeight)){ = current_size + 'px';
        height = elem.offsetHeight;

Bring any window to the front

A question was asked on the apple dev mailing list on how to bring a window with a certain name to the front.

Since I was already working on how to get the list of windows on the screen, I just added some AppleScript to bring the window to the front.

This snippet doesnt use any undocumented techniques, it uses the CGWindow API introduced in Leopard.

I dont consider this code to be production ready, but it works.

Of course, TIMTOWTDI 😉
