After that I implement a Cancel method pointing to sender (button)
So, my goal is to use 1 start button and 1 cancel button.. and just do their actions. I have set up a the start button to start both timers, obviously both start their countdown at the same time which is not good.
I want to tell one timer to start and if I press cancel, invalidate it. Then If I press start again, call the second timer. (I do this because I read that you can't reuse a timer after you invalidate it).
Some people have suggested to use Booleans like true or false, or conditions. What do you think?
What if after pressing the start button, you create a timer and start it. Then pressing the cancel button invalidates and releases it. Then pressing the start button would create another timer, using the same pointer.
Totally untested and probably broken code below, but should demonstrate the idea:
-(IBAction)startButton:(id) sender {
// myTimer is declared in header file ...
if (myTimer!=nil) { // if the pointer already points to a timer, you don't want to create a second one without stoping and destroying the first
[myTimer invalidate];
[myTimer release];
}
// Now that we know myTimer doesn't point to a timer already..
myTimer = [NSTimer scheduledTimerWithTimeInterval:aTimeInterval target:self selector:@selector(echoIt:) userInfo:myDict repeats:YES];
[myTimer retain];
}
-(IBAction)cancelIt:(id) sender {
[myTimer invalidate];
[myTimer release]; // This timer is now gone, and you won't reuse it.
}

Overthrow of the government?
:confused: i suppose that's the only definition for revolutionary for you? if so, what do you see in iPhone that's revolutionary?
And only 200 new patents.
is there anything other than the fact there's "200 new patents" (where did you get this anyway?) that you find revolutionary about iPhone?
Apple is not a religion, Steve Jobs is not God.
i'm outa this thread.

The 20" is still way over-priced.
yeah, but it has an apple logo and is made of brushed metal. if you don't like to pay for design, run unix on a homebuilt PC in a square plastic case.

please tell me you know about the process of obtaining a patent.
if i have the money, i can come up with 5 things, right now, to be patented. but you don't care, do you.
point being, it's not hard to get patent... as long as you fulfill those 3 requirement (novelty, non-obviousness, usefulness), and after a few yrs, you will be grant a patent.
the lacks of buttons on a phone could ne novel and non-obvious, but is that really THAT exciting? sure it's great and all, but c'mon, it's not revolutionary.
i'm not saying iphone is crap, it's just disappointing from all the hype.
no offense to you but... if you didn't like all the hype, you should stop reading rumor sites before announced events...
but again, only a deaf and blind person (again no offense to those who are) wouldn't have heard at least of a rumor about an apple phone. a normal educated adult with internet connection and/or tv has heard about this rumor at least once in the last few months...

Hello "lawyer". No legal permission is required for reverse engineering.
The DMCA changed that, and until it's tested in court anything where encryption is used or even potentially used is not "safe" to reverse engineer in the US.

you Americans have some ridiculous proverbs/figure of speeches that no other Anglophones around the world can even attempt to understand.
And the English language's inception was here in England so why do Americans spell rumours 'rumors'? And there are an abundance of similar examples.
Try being an American and writing words like "tyre", "colour", "aluminium" etc. I always try to use the correct "English" spelling of words and people give me crap about it. I just tell 'em that's the CORRECT way to do it, and the sun never sets on the British Empire. They usually leave me alone after that. :p

Man, I always wait till after midnight to check for new music that gets released on Tuesdays. Now that Apple has gone and changed my life in some inconceivable way again, I'll have to wait till this afternoon to get my new album fix from them.
Yea, there was an album that just came out today that I was seriously contemplating purchasing. I even found it this morning before the store went down.

In terms of new stuff I think just the thin portable, as that's the only thing there's been any leaks/evidence for (the leaks usually have everything covered!)
Other than that, refreshes - in order of likelihood: MBP refresh with the new keyboard (even tho I think it'd look a bit odd if it's white), 16GB iPhone (not 3G yet), Glossy ACD option, Cheap ACD option (watch for the gradients and poor quality!), MacBook refresh, maybe some tweak to the ATV, maybe a non Glossy iMac option (just to wind up those who bought an iMac and dislike it!).
Things I don't expect them to update: the iMac (already done recently), the Mac Mini (ditto and they don't like updating it), or any of the iPods (also too soon) or the Mac Pro or XServe (that would be silly, and the place would get firebombed)

Any word on whether there'll be an update for iPhone 3G users? The highest version of iOS they can use currently is 4.2.1, which presumably has the location cache problems too?

Good.
How is the new office Eric? What goes around comes around. The walls are starting to lean.
The future is WIN7, iOS, and RIMM. :apple:
I am more curious how the labels are going to try to renegotiate contracts with Apple once Steve moves on.
I am not too sure Tim Cook or anyone of his pay grade is as tough as Steve is when it comes to these label execs.
Do more research on Tim. Steve picks the target. Tim delivers the system.:apple:

LOL at the perspective on the text in the 3rd photo.
Actually, shooting up close with a wide-angle lens will give you exactly that distortion. Here is a photo I just took of a REAL iPhone with a 17mm lens. Sorry about the fuzziness - handheld and did not use a flash:

So I don't think text in the 3rd photo is skewed. That being said, I agree it's a fake.

I'm pretty happy that my 15" Powerbook is officially supported to run Aperture now. They must have reduced the system requirements, which might bode well for those of you with faster machines in terms of program performance and speed.

I remember a girl/woman submitting such an app to Apple.
It was rejected on the grounds:
'Not required => redundant'.
I see something changing now. :rolleyes:

There aren't exactly good public restroom options for a transgendered person. I think when it comes to restrooms, you probably should pick the door that reflects the body parts as you have them, not how you want them. Wouldn't these same girls be widely considered justified if this was some skeevy guy in a trench coat?
Does anyone know if there is an affirmative duty for non-security employees to intervene in fistacuffs.
(edit) I can't watch the video, but I'll take your word that no one called the police. If so, that may subject the entity to liability for failure to minimally protect customers. The yelling may be despicable, but that won't be enough to subject McDonalds to liability.

Awesome, to make enough time for this lets just forget everything after the Great Depression because it's not like that junk matters as much as gays being persecuted. Seriously, the Holocaust and the Rape of Nanjing are totally trivial events compared to the Stonewall riots. We should totally drop coverage of the bombing of Pearl Harbor to make room for a lecture on how NAMBLA doesn't represent gays. To top it off we should ditch the civil rights movement in favor of the White Night riots!
:rolleyes: there is no time available to teach this, if we teach this something else gets whacked. As is we get to the 1930s by the tests which go to the 1980s...
