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.
}

I booted into snow leopard on another partition after using Lion for a while and I had trouble not scrolling inversely. I've gotten quite used to it.
Agree that Lion scrolling makes more sense now that iOS is so popular. But the odd "slider" tab controller really didn't make sense to me. It was animation for animation's sake.

The slow pace of messages here shows that this has gone from being important to the masses and the trolls to now be a small problem. Previous threads (those from before the videos and pressconference) added three pages in the time it took to read one, there was just no way to keep up with them. This has still not gotten much over 50.
It is interesting, but few considers the new iPhone to be broken anymore. No matter what you think of how Jobs handled it, he completely defused a situation that was becoming very hostile. I'm sure this will be taught and dissected at universities for years just as Intels poor handling of PR with the "faulty" processors is taught as the difference between dealing with companies and customers. This was a lesson for all and many key bloggers have already written pieces of how he changed the usual dynamics of apologizing for any perceived issue.

Thats a loaded demand since you already agreed with my later statement that they need to learn how to vet online sources like they do print sources. I can list off any number of magazines or whatnot that would do such things if given the chance, though. It isn't like gizmodo invented pranking, guys.

He didn't do it by himself. There was a whole company working on things. The difference is that he had a vision of what should be happening.
It took smart people in all areas to make Apple what it is today.
What about all the former Apple CEO's. They had a company behind him too, but he simply could not lead like Jobs can.

Who is this "untoward person"?
What would the "issue" be?
e.g. paedophile. Issue is rather obvious.
How would they acquire the data? How would they know this is a young person they actually want to follow? Couldn't they just follow them home from somewhere? Does the person need to lose their phone for a danger to occur? Does this paedophile need to have a phone with them?
The tracking that is occurring is by cell tower identification when someone is in range of one. Will the paedophile have access to a spy satellite to zero in on the exact location of an individual?
I'm still not buying it.

This sucks. I don't want to have to pay Verizon an extra $20 a month on top of an already expensive phone bill to do this crap. Will this affect using PDAnet on a jail broken iPhone?

Apple will need to open up osX to generic PC's but i can understand they'll want to wait until the Mac growth is stalling. Maybe at about 10% marketshare ?
Science fiction scenario: Five to seven years from today Apple and Hewlett Packard partner. HP gives up on Microsoft/Windows and ships machines with either Mac OS or Linux. Dell considers joining the club, as well.
Another five years later, Mac OS market share approaches that of Microsoft.
:cool: ;)

T-Mo may have screwed the pooch on their 3G rollout, but my phone doesn't drop 30% of my calls. It'll be interesting to see how ATT, and TMo keep up with the 3G coverage, as Verizon and Sprint move forward.
My iPhone never drops calls and hasnt since after the first few months the 3G luanched. But I am not in New York or California! :p
I did have a hard time sending MMS the week it launched. Lots of sending errors. And tethering...... how about that AT&T? :rolleyes:
I want another US carrier to get the iPhone, if for no other reasons than to just spur competition and get a big load off of the AT&T network.

According to the new features list for Aperture 1.5
"Run Aperture on any Intel-based Mac. Any desktop, including Mac mini, iMac, and Mac Pro. Or any notebook, including MacBook and MacBook Pro.
"
That is good to know, because 1.1.2 runs like crap on a Quad with a 6800GT and 8GB of RAM. Unacceptable, really. I basically abandoned the workflow and went back to Photoshop. I can actually get work done that way.
Aperture IS great for cataloguing, though, so for that, I am grateful.
Glad 1.5 ia a free update, too.
this doesn't mean there will not be any updates to the MBP on Tuesday.
I totally agree - today was NOT the time and place, though. ;)

I have to say this game kicks the crap out of Modern Warfare 2 which felt dull and boring in multiplayer mode. The maps are far more varied than in Modern Warfare 2 and much more interesting. The game modes are pretty good and the best thing about it is the customisation you can do. Plus the new leader boards are good for those of us who are pretty competitive.
Overall I'm much happier with this game than I ever was with Modern Warfare 2 which I only ever played FFA on and people always used to cheat by using Tactical Insertion to sit next to each other and get free kills.

I think I'd prefer a system where only upvotes ("likes") are allowed (e.g. Engadget). That way you can still see who's got the most positive/popular posts while not opening it up quite so much to abuse or the negative connotations associated with a negative score.
Another forum I visit (RedFlagDeals) has a similar system where people can be "thanked" for particular posts, and then their user profile shows how many times in total people have thanked them. It helps show who is the most helpful or who has a good reputation for providing useful advice.

This rumor should sound familiar to anyone that followed Dell and their long courtship with Intel. One analyst/pundit after another announced a rumor that Dell would put AMD into their grey boxes and year after year they were wrong (until this year :) ).
But seriously, I would welcome this move. Keep Intel (C2D, C2Q, and future) on the high end Pro models, use AMD with ATI integrated chipsets on consumer models. Or if/when it happens switch so that whatever is the best performing cpu/chipset combo is in the Pro line and vice versa.
