By the way, what's with 3rd person reference? the OP? you can call me Nekbeth or Chrystian, it's a lot more polite. Maybe you guys have a way to refer to someone , I don't know.
I appologize for that. I didn't recall your name. I was replying to KnightWRX, so I took a shorcut (original poster).
I won't do that any further.
I through together a simple program that I think does exactly as you want. It is a Mac version, but the different there is trival, and instead of a picker, it is a text field the user enters a time into for the timer duration. You will need to change the NSTextFields into UITextFields.
The bulk of the code is exactly what I posted before, but I modified the EchoIt method to work with an NSDate. I implemeted it in the appDelegate, and you are using your viewController. That doesn't change the code any, and your way is more correct.
I can email you the whole project as a zip if you want. It is about 2.5 meg. Just PM me your email address.

*edit:
If you like, later tonight I can show you how to do this as you first tried, by incrementing a seconds variable. Or wait for KnightWRX. My concern is accuracy of the timer. It might be off by several seconds after running an hour. That might not be an issue for your application, but you should be aware of it.

already exists - Amazon Cloud/Music Player
Yep. I had an android phone for a year and a half before the Verizon iPhone came out and routinely bought tracks from Amazon; moved them over to itunes, etc. Android users are SOL for movies and TV shows, but Amazon fully covers music. I don't see why Google is bothering to negotiate.

Typical promotion of homosexuality. What else is new. They gotta find new ways to bankrupt us here in California.
I'm beginning to think that on a lonely, quiet Friday night this is the most action that Calidude can hope for.
I'm 50 ... and married, Calidude.
What's your excuse?

Overall, disappointing.
From the MacRumors live update (thanks guys), there was waaaaaay too much dull stuff about movies /snore Agreed.
Someone needs to ask Steve (the nouveau movie and entertainment mogul) the same thing he once asked John Sculley:
"Do you want to spend the rest of your life selling cartoons or do you want to change the world?"

Windows are purely OS for "work enviroment". OSX is for casual stuff.
Cant imagine using freakin Miranda/ICQ/Trillian/Digsby piece of crap with MS Movie Maker and so on.
Same as i cant imagine using Outlook/Excel on Mac OS.
Windows is like Semi, gigantic ugly looking utility vehicle. Mac OS is like convertible ferrari - nice pus.sy magnet for everyday casual use.

Nothing on the cinema displays? Does anyone else think the displays are rapidly loosing market share due to a lack of updates over the last 18+ months?
i agree. I think it would have made sense to drop them in price in line with the mac pro update...and they didnt
so i then thought there was something new and radical at macworld...and no.
only thing i can think of now, is that they will get an update alongside a mac mini update (whenever that happens) because IMO they are starting to look very overpriced!

How does Gnome 3.0 on Linux compare to the new UI in OSX Lion?
I've been playing around with Gnome 3.0, and it seems like the designers have a similar philosophy about desktop navigation.
Gnome 3.0 Preview (This is not my video):
http://www.youtube.com/watch?v=joBXc3IGRBw
That's a pretty sick OS. I haven't ever run Fedora on a computer of mine, but my uncle swears by it. That video has convinced me to run it on my next box.
I like fedora over ubuntu. I haven't run fedora for a while, I think I'll take second look when the new version comes out.
I wish Ubuntu went with Gnome 3 over Unity. Fedora is great but it is more "free" than Ubuntu as Fedora includes fewer/no? proprietary drivers by default so it is a little bit more work to get running on some hardware.
The next Fedora may be worth the extra effort.
Here is a link for those looking to stay up to date on Win 8. http://www.winrumors.com/
Or, at least looking to retaliate?

You're classy.
I hope karma greets you tomorrow morning with a swift kick in the mouth.
Not to condone OP's actions in any way, but karma isn't real.
People should conduct themselves according to their moral code, not out of fear that the universe will somehow reward or punish them. This is the 21st century, it's time mankind grew up and took some personal responsibility. There is no "higher power" judging our actions.

You do know that Windows had an App Store before OS X, but it got axed due to it being badly implemented which resulted in lack of custom? All they are doing there is returning and improving one of their own features, not copying Apple.
If we consider only games, Microsoft's own game store has been running since December 2009. Games for Windows LIVE Marketplace.

It's not only new territory, it's outside their core competency. Like Cisco selling cameras or Google selling phones.
Its this closed minded view that separates risk taking leaders from regular employees.
To prove this, all one has to do is look at Apple's success in portions of the tech sector that they previously had not occupied.
Never say never :)

One thing I willask about all of this children/peadophile spin is why are these theoretical parents putting their children at risk giving their children such "connected" devices?
It's simply asking for trouble.
Little children that are at risk to that sort of thing shouldn't have cellphones, let alone iPhones or their own computers :eek:

lets hope we get new MBPs before Macworld in Jan!
in Jan i hope to get iTV, iLife '07, Leopard and maybe an iPhone
I would like to see iTV a cross between Tivo and Front Row
There is not much i would like to see added to iLife but i bet Steve will make my buy it
I reaallly don't see Leopard being out in January.

Looks like your production has started again, great. Also Designed is back after a little hiatus, and Lizardking has crunched a bigadv again after a long pause too, and Whiterabbit production is as high as ever. We could be raking in some serious numbers this week :eek:
If Apple release 12 cores, I might splurge if the team is cranking too!
