Iphone stopwatch - start, stop and start but doesn't start off with where it left off


I are trying to make to a stopwatch app and facing problems getting
it to work properly. When I start the stopwatch and stop and start off
again, it doesn't continue from where it left off. It carries on
running as if it didn't stop. Need some guidance on getting it work
properly. I have been trying since morning, the rest of the functions
i have made as similar to the apple's stopwatch, only this is bugging
me.. Appreciate any help...


The code looks like
this:


ViewController.h


#import
<UIKit/UIKit.h>
@interface ViewController :
UIViewController<UITableViewDataSource,UITableViewDelegate>{ /> UI

Is it possible to get this iphone app
(http://www.apptite.be/tutorial_ios_stopwatch.php) to start and take
the lap times based on Longitude and Latitude? So instead of having a
start button when the phone goes past the GPS coordinates the timer
starts and everytime it goes past the GPS coordinates it takes a lap
time and stores it in the sql database.


Hope this makes
sense...


Thanks in advance :)

I have a very specific question that I need answered for a very
specific performance test. I will simplify the code, to make it easier
understandable.


I do many calculations (a few ten
million), all done in loops that are themselves not too long and I
need the total calculation time. However, all the calculations are not
done directly one after another and some extra code "comes inbetween"
every loop.


What I need, is quite exactly the total time
of all loops (including declaring and initializing i, incrementing it,
and comparison with 100 in exmaple). To measure the time I start a
Stopwatch directly before every loop and stop it directl

Server shuts self off from the world, httpd stop, start, stop,
start then it works ag
 
ain...
Anyone know
why?

doesnt know why its doing it (he set the server up.)
So I thought

Here is what I have so far. It is working, however now they have
requested to have separate buttons for start, stop and reset. I am
totally new to C# and was hoping someone could help me separate the
one button I have into 3 buttons instead:

class="language-cs">using System;using System.Drawing;using
System.Collections;using System.ComponentModel;using
System.Windows.Forms;using System.Data;using System.Text;namespace
stopwatch{/// <summary>/// Summary description for Form1.///
</summary>public class NextGenTimer :
System.Windows.Forms.Form{DateTime da ;private
System.Windows.Forms.Label label1;private System.Windows.Forms.Button
button1;private S

I am creating a stopwatch and the start and stop functionality is
not coordinated. When the timer stops, it doesn't start where it left
of.



The code looks like this:



self.endDate = [NSDate
dateWithTimeIntervalSinceNow:12.0f*60.0f];

-(void)startPressed:(id)sender{
if(!_running){
_running = TRUE;
[sender setTitle:@"Stop" forState:UIControlStateNormal];
if (_stopTimer == nil) {
_stopTimer = [NSTimer
scheduledTimerWithTimeInterval:1.0/10.0
target:self

selector:@selector(changeTimer:)
userInfo:nil
repeats:YES];
}
}else{
_running = FALSE;
[sender setTitle:@"Start" forState:UIControlStateNormal];
[_stopTimer invalidate];
_stopTimer = nil;
}

}

- (void)changeTimer:(NSTimer*)timer {
_timeInterval = [self.endDate timeIntervalSinceNow];
self.timerControl1.minutesOrSeconds =
((NSInteger)_timeInterval)%60;
self.timerControl2.minutesOrSeconds =
(NSInteger)(_timeInterval/60.0f);
self.timerControl3.minutesOrSeconds =
((NSInteger)_timeInterval)%60;
}


I know it is because of timeIntervalSinceNow. But, how to change
this? Need some guidance on this.
