Define the variable outside the interface on the .h file.

</pre>
// two different examples to show an object too (class main.h)
<pre>
int gMoveNumber = 0;
NSDate *theDate; // then set it somewhere in the M file or outside using extern

@interface
…

Then call the variables from any other class like this (say class something.m)

extern NSDate *someDate;
extern int gMoveNumber;

NSLog(@"Date: %@", someDate);
NSLog(@"Move Num: %@", gMoveNumber);

David Hockney has always been such an innovator. Now, at 73 years of age, he come up with a crazy iPhone/iPad exhibition.

Remember, this was the guy who came up with the idea of overlapping images to create a larger image. We all know lenses never fit enough of what we want to show, he just didn’t put up with it and found a way to fix that. Very clever artist.

Whoa, slow down there, maestro. There’s a *New* Mexico? Marge, you being a cop makes you the man! Which makes me the woman — and I have no interest in that, besides occasionally wearing the underwear, which as we discussed.

Both the Palm Pre Browser and Mobile Safari (iPhone, iPod Touch, iPad) can make AJAX with XML from a local page. Meaning if you’re using Palm Mojo and you want to retrieve some XML from wherever to your app you can. Same thing on the iPhone if you’re making Apps with HTML 5 using Phonegap or something similar. You can do the request if your file is local.

Now, cross domain like from one domain to another, I don’t know. But I do know something, this that I mentioned here does not work from a browser on a computer. At least not on Firefox, IE and Chrome (both Mac and PC).

Update October 27th 2010

Wrong, wrong, wrong. On the Pre yes, it does work. I only tested with Delicious.com, though. They might have their server settings set to allow cross-domain requests. On the iPhone it didn’t work at all. We ended up having to use a proxy script to translate JSONP into XML. The script runs on the server where the backend lies and it talks to the web-service.

My tests were not done properly. I was just pulling an XML document from another server. If you actually try to make a SOAP request from the iPhone using javascript, good luck.
