So, please don't take everything I typed and generalize it, because it's not for everyone.
I do understand where Dejo, Balamw and the others are coming from though. And frankly, they are probably better suited to help you than I am. I don't have a lot of experience with Objective-C and Cocoa, not like they do, having mostly come into it recently.
Back to the code, here is a photo of my connections (ignore canceBigtimer). What you say is true I don't know how NSTimer works entirely , just some parts, I realize that and it is one of the reason I postpone my timer for a future update (need to study it).
I have two timers, because, like I said.. I don't have full knowledge of timers. I know now that 1 timer is enough, even if I use two timers and start them at the same time, the log only shows 1 loop and the countdown in separate labels show e.g. 59 in one and 58 in another and so on.
Ok, how about we work on making 1 timer work then ? The code you posted is very complicated and I don't think it has to be this complicated. Going 1 timer would simplify this.
I see your Start Button is associated to 3 actions. Is this really what you want ? Let's simplify this. As an exercise, make 1 method, call it startTimer (like I did) and have only that action associated with your start button. From there, you can call the other methods yourself as needed.
Once you have modified the code in this way, post again what you have in full, what it is doing and what you think it should be doing. We'll go from there.
You mention my two global variables, It makes sense that the timer does not stop because the variables are outside the method that creates the timer. is that whats going on?
No, the variables are "fine" where they are. They would be better positionned in the @interface block and declared as instance variables, but implementation scope globals work too.
What you need to do however is reset those if you want your timer to start back at 0. Somewhere in your "stop/reset" code, there needs to be an initialization of those back to 0 :
seconds = 0;
minutes = 0;
If your Cancel button is what should reset it, then this should be right now in newActionTimer. But ideally, we'll get rid of that function when you simplify the code down to 1 timer.
Look at my NSLog outputs in my screenshot earlier. There's 3 methods there. updateLabel, cancelTimer, startTimer. This should have given you a big indication of how not complicated you should have made this.
If you want 3 buttons, start, reset, stop, you'd technically need 4 methods, as follows :
-(IBAction) startTimer: (id) sender;
-(IBAction) stopTimer: (id) sender;
-(IBAction) resetTimer: (id) sender;
-(void) updateLabel;
One to update the label as needed, one to start the timer, one to stop it and one to reset it.
Also, NSTimer is not your timer. The timer is what you are creating with ATimerViewController. You need to grasp this. NSTimer simply calls methods, in this case, it should be update label. That's about all it should be doing. Both the stop and reset methods should release the NSTimer object instance. startTimer should always create a new one. However, reset should be the one to set back seconds/minutes to 0.

how do you change the weather location .. ive looked everywhere ..

I would just download the 99c app if you don't want to deal with modifying the file in the root folder. Then you're good to go.

That doesnt look right.
Square on the sides instead of the way it is now.
And whats that wide slot on the side?
Also theres traces of photoshop usage on those pics they say.
Besides, why would anyone especially want this? At least if you're going to PS, make it a good one.

Never underestimate the storage capacities people will require! It wasn't THAT long ago I remember having a 10 *megabyte* hard disk drive on my old TRS-80 computer and thinking "This thing is HUGE! I can store every program I own on here AND all my data!" And we all know the ever popular "640K should be enough for anyone!" quote regarding RAM memory.
But if you're talking about simply the "here and now", yeah - the typical user won't have a good reason to store 30-50GB on a single piece of media. On the other hand, someone who works with video a lot easily might. (Think of the idea of making a single disc that contains a full collection of HD video clips you made and edited so you could copy/paste them into future projects, at will.) Sort of like those "50,000 clip art images collection!" CDs people buy, except your own, personal HD video version.
I'd also imagine this would be nice for corporate backups. People currently shell out around $90-100 each for DLT or LTO type backup tapes that hold maybe 40GB or so of compressed data. They could substitute one with HD-DVD or Blueray media and have more reliable backups with easier, quicker retreival too.
That comment about not including the burner is interesting, and I'm at least trying to give it some more thoughtful consideration. Who really needs to burn 30 - 50 GB of data? For backup solutions, wouldn't just getting a huge external hard drive be more practical? Portability might be a factor there, but external drives aren't that cumbersome I don't think. I'm thinking that the majority use of those HD media burners would be to copy movies with illicit applications. Could Apple put in place some protection framework that attempted to only allow creative-works-originating software to burn HD discs, (ie, iMovie, iDVD, FinalCut and other pro apps that use full quality, large size files) therefore denying use of a program that takes a quick and dirty imported disc image and burn it to disc, so that you'd have to work around some long and annoying solution to make an illegal copy (ala burning audio CDs in iTunes and reimporting them to strip the DRM) that would deter any easy mass pirating?
More simply, I'm curious of who out there needs to burn 30 to 50 GB chunks of data, too large for a dual layer DVD to hold, and why.

The thin veneer is off the vast majority of people that clamor for OSS.
Whenever I hear the OSS crowd scream "Software should be FREE!" I translate that to mean "I refuse to pay someone for their work, thus I will STEAL it"!
I don't blame Apple. The OSS community abused what they had and turned to piracy by stealing the GUI. Kudos Apple.
:rolleyes:
Anyone who understands what OSS and or "free software" is knows that they're not talking about money when they say it should be "free".
From http://en.wikipedia.org/wiki/Free_software (emphasis added):
To help distinguish libre (freedom) software from gratis (zero price) software, Richard Stallman, founder of the free software movement, developed the following explanation: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech', not as in 'free beer'". More specifically, free software means that computer users have the freedom to cooperate with whom they choose, and to control the software they use.
Are there people who steal software, yes - but that has nothing to do with what we're talking about here.
FWIW: I work every day developing commercial web sites with free software (JBoss, Tomcat, Ant, Apache, gcc, Red Hat Enterprise Linux, Eclipse, etc...). Why? Because we don't want to pay for it? Hell no! We pay a lot of money in licenses and support contracts just like we would for non-OSS products. The difference is that, when needed, we can see why the software acts the way it does and even can change it if we find it necessary. We don't have to rely solely on a vendor's promise about how secure or optimized their code is because it's wide open for all to see. THAT is what OSS is all about.

The point dejo was trying to make, is that you are missing a VERY basic Objective C (well, any language really) fundamental.
This:
- (void) cancelIt:(NSTimer*)timer
does NOT create an object.
It's simply a map to say "When I call this method, I will pass in an existing timer object". It is still your responsibility to allocate/initialize a timer and then pass that into your method. Simply using the selector as you are doing wouldn't accomplish this.
At some point you would have to do something like:
[self cancelIt:MyExistingAndValidTimerObject];

I can assure you all I'm not an idiot or moron.

MOR- oh nevermind. :p actually I downloaded it long ago! haha. Just for kicks. It's pretty well made. And I remember when iAds first came out I was actually wanting something like this because I actually did want to see all the different ones. They are moderately entertaining and if the product interests you it can be informative.
That being said I'll probably delete it like tomorrow...

wow, you try to shut down a whole shop because they hurt your feelings?
Ever thought of the many people who depend on working there? What unbelievable egoism.
Well, to be fair I have no idea what happened but depending on what they did, it could be very unfair to say they just "hurt his feelings".
That being said, yeah, I think that poster is being a little delusional that they'd shut the whole store down over what he did.
At best Best Buy fires anyone involved that caused them to have to pay out some large fine and maybe any of the managers that were around at the time. But they aren't going to shut the store down over it. And that is how it should be, cause the whole store shouldn't suffer because of some really bad employees (but the bad employees should be gone).

After a quick look around the forums it appears as though other places like the UK are getting a sale on the 1st too. Nice to see Apple going a bit more global with this stuff.

The moment you've got a life to lose if you're sued and you have your hds full of pirated movies, music and stuff would be a good point to start being worried. About that life of yours if you're having a job and a family and things like that. Could get nasty if you're having a criminal record and things like that, you know.
And how exactly would they know to sue you in the first place?

Go ahead and opt out of your full-body scans... if you're doing it for the "health" reason you're tilting at a very small windmill.
The "Health" angle is murky, but TSA uses opt-out ratios as proof of acceptance. They've put out multiple press releases pushing >2% opt out rates as proof that people feel safer and don't mind the new security measures. So, I'm going to opt out every time, if for no other reason than to drive up the cost for them.

Yes, I have the Samsung 46" LN-S4696D (http://www.samsung.com/Products/TV/LCDTV/LNS4696DXXAA.asp?page=Specifications), connected to both a Samsung BD player and a Core 2 Duo Media Center Edition mini-tower with a Quadro FX graphics card and HD tuners.
It does 1080p native, as well as native 1920x1080 on the PC.
Some of the Blu-ray Discs are simply amazing (House of Flying Daggers is superb), although others just make the shortcomings of the original production more apparent. (Kind of like a CD of an old live concert, where the CD perfectly reproduces the hiss and noise in the master tape.)
If you get the chance, watch either ultraviolet, or Underworld 2 on your BD player. It looks so good, it's rediculous!
