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.

seems sketchy, Apple wouldnt put it all in VZ's hands at all to keep it secure, Apple does a fine job at that already.
And i dont think itd be that much of a difference if they release att / vz iphone separately they do device updates for portables, desktops differently and the usual ipod updates etc.
But the fact remains how are they going to exactly implement two separate phones for carriers that use different cell tech, and implement them properly
I highly doubt there will be a vz iphone for as much as id like one...not until other 4g/lte services are out in the wild

I agree with 'CWallace', I'm pleased with what Apple released today. A few minor gripes, but pleased overall. I believe many of you are suffering from "overhype hangover".
Had this been an unannounced unveiling of new products and software by Apple without all of the pre-hype, I think many of you would not be as harsh. But with months to hope, wish, and speculate and given the vivid imaginations of those in this forum, you were doomed to be disappointed.

One possibility that came to mind is that the cashier guy let him get away with it because he intended to pocket the cash himself.
And he would do that how?

Honestly, I dig the look of it but I have my doubts about the sharp edges. I can almost promise you that the photos are faked but I'm seeing that most of us already know that. I can see the body being aluminum- isn't the Droid aluminum? There would definitely need to be a place for the antenna- black plastic or something.
I'm hoping for something different this time. My 3G has held up well except for a broken ear speaker, but I'd like to see them push it a little as far as design. Every time I see an EVO 4G- I look at it longingly.
Haha, "pushing" the design. Thats very tempting, many companies do just that. Fortunately Apple DOESNT!

HD DVD for movies and Blu-Ray for data. Problem solved.
Personally, I would rather just have digital downloads from a high speed download service and store them on my own storage whether it is on DVDs, Blu-Ray, HD-DVD as data. For large downloads, I would like to go to a local video store and download them to my laptop using Firewire 800/400 or USB but that is probably too far in the future.

Competition for itunes would not be a bad thing but those record companies are just too greedy!
There are plenty of competition. Look back the history for the past 10 years. Almost all of them, including Microsoft's versions, failed against iTunes.

Thanks for the feedback on the preferences for the scrollbars, folks...I removed it from the article.
You should have made mention of the edit in the actual article. I thought many of the early commenters were making things up until I realised they were just commenting on something from your original post.

I hope this is true... I really would like to have a more rugged case design on the iPhone (planning on getting the next version). I had the 3G iPhone and the back plate always felt flimsy / fragile.
For the antenna - could the antenna placement be put near the apple logo on the back (maybe that is plastic) or -- might there be enough antenna surface to receive through the front?
I also wonder if they could tie an antenna to the bezel on the front of the phone, or integrate it into the aluminum enclosure on the back. Not knowing metallurgy, I am not sure if there is a way to turn aluminum to a receptive material or could the case be of an aluminum alloy to allow reception?
No way Dude.
All of the phones that I see open to see the internals had metal shields in the front to get less radiation from the antenna.
It is still not proven whether or not U can get cancer from radio waves.
But,I do know certain places where radio waves will kill U.
Don't even come close to a very high power antenna from a radio station,a T.L. will even light up if you hold it nearby.
Making an antenna of the aluminium casing is impossible,don't U think Apple and others would have done that long time ago:eek:

oh btw..a hint...if you go to an apple store and buy a giftcard for the amount you need online...then you can use the gift card..get free shipping...plus get your 100 bucks off on a macbook w/ educatoinal discount and have no tax...
so you really end up saving 200 bucks....thats what im doing just a heads up
Could you explain?
Thanks.

What kept me often from buying apps was the too complicated paying system: You have to register, give them the number of your credit card, remember the password of the login and so on. The MAS makes this a lot easier and safer. Apple's decision to only allow MAS apps for the Design Award is to push developers to publish their apps on the MAS. What's wrong with that?
What's wrong with it is it expressly denies potentially stellar Mac apps from possibly winning the award, due to Apple's arguably arbitrary "rules" as to what apps are allowed in said store.
Rather lame considering Apple's own apps seem to be except from the same rules.

1.ACD Updates (Touchscreen, iSight, Firewire 800 added ports built in, better res, contrast, etc....
2. iPhone update to 3g and 16GB model for $449 and 8GB now only $349.
3. Apple TV/Movie Deal, Rental Deal. 250GB Apple TV with 1080p output and iTunes Purchases for movies and HDTV shows, up to 720P Res. downloads.
Or at lease I hope for #1. I doubt it, but if my dream came true I would buy one and a ton of apple stock.:apple:

I think the Volt is a success in terms of meeting it's intended design parameters. However, I think the whole notion of the all-electric car and plug-in hybrids are flawed due to our current infrastructure.
As long as we burn fossil fuels to get the electricity, the electric car is just sweeping the fossil fuel/pollution problem under the rug by putting the "dirty" side of power consumption out of sight (back at the power plant). Also, there's no way our current power generation infrastructure could support even a fraction of the population switching to electric cars. California already has rolling blackouts - if people stopped burning gas and switched to electrics, the problem would get drastically worse.
I think electric cars are a dead end for the present...At least until our entire power grid makes large-scale switches to alternative energy, and there is no timeline for that currently. Also, there is currently no guarantee that practical fuel-cell systems will ever be truly affordable or mass-producable. The current offerings are all extremely expensive, proof-of-concept vehicles with short useful lives.
We'd be better off with diesels or diesel hybrids. People don't want to admit it, but those are currently our best options IMO.
I really wish I didn't sound so cynical, but that's the picture as I understand it.
All very valid points. However, keep in mind that even how we get our power varies from state to state. Switching to electric vehicles does need to come hand in hand with a change on not only how we generate electricity, but also how we consume it.
