Self terminating beta code

[truehybridx]

hey guys, im taking a dip into OSX developing and im making fair progress in my first few apps for both iphone os and osx, but i was wondering if theres something i can put in the code that makes the current beta build run for only a few days, and after those days the app refuses to launch.

Id rather it be a time limit as opposed to a certain number of runs, but whatever is more practical will work

THANKS GUYS!!

When it launches, check the date, if it's past the expiry date, show a little message explaining, then quit.

would you mind giving some sample code on doing this?

No problem,

NSDateFormatter * newFormatter = [[NSDateFormatter alloc] init];
[newFormatter setDateFormat:@"dd mm yyyy"];
	
NSDate * endDate = [newFormatter dateFromString:@"04 01 2010"]; //This is the end date, this is what we're checking for
[newFormatter release];
	
NSDate * nowDate = [NSDate date];
	
if ([nowDate compare:endDate] == NSOrderedDescending){
   NSLog(@"expired");
   //Show message, then quit
}
else
{
   NSLog(@"nope, still good");
   //It hasn't expired yet.
}

I created endDate in the way shown above just as a quick example and doesn't have a time or anything, just a date. The important bit is the comparison to see if the endDate has passed.

so if i know my stuff right, i would pop this into the applicationDidFinishLaunching method? or is that only in the iphone version?

also how do you make the app quit? on both OSX and iphoneOS

[harrytheshark]

Yeah, that's right.

I think you can quit both by doing

exit();

But I'm not 100% sure.

applicationDidFinishLaunching()

doesnt get called or something but the best way i found to kill an app in osx is

[[NSApplication sharedApplication] terminate: nil];

ok i never set the .m i was using to delagate the method so it was never working right, BUT now it does yay!! thank ya~!!

-(void)applicationDidFinishLaunching:(NSNotification *)aNotification {

}

Is available on Mac OS X
