hi, i have a nstimer and it works perfectly counting down from 2:00 but when i hit the reset button it does not work it just stops the timer and when i press start again it will carry on with the timer as if it had never been stopped. Here is my code `@implementation TimerAppDelegate
@synthesize window;
(void)applicationDidFinishLaunching:(UIApplication *)application {
timerLabel.text = @"2:00";
seconds = 120;
// Override point for customization after application launch
[window makeKeyAndVisible];
}
(void)viewDidLoad {
[timer invalidate];
}
(void)countDownOneSecond
{
seconds--;
int currentTime = [timerLabel.text intValue];
int newTime = currentTime - 1;
int displaySeconds = !(seconds % 60) ? 0 : seconds < 60 ? seconds : seconds - 60;
int displayMinutes = floor(seconds / 60);
NSString *time = [NSString stringWithFormat:@"%d:%@%d",
displayMinutes,
[[NSString stringWithFormat:@"%d", displaySeconds] length] == 1 ? @"0" : @"",
displaySeconds
];
timerLabel.text = time;
if(seconds == 0)
{
[timer invalidate];
}
}
(void)startOrStopTimer
{
if(timerIsRunning){
[timer invalidate];
[startOrStopButton setTitle:@"Start" forState:UIControlStateNormal];
} else {
timer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDownOneSecond) userInfo:nil repeats:YES] retain];
[startOrStopButton setTitle:@"Stop" forState:UIControlStateNormal];
}
timerIsRunning = !timerIsRunning;
}
(void)resetTimer
{
[timer invalidate];
[startOrStopButton setTitle:@"Start" forState:UIControlStateNormal];
[timer invalidate];
timerLabel.text = @"2:00";
}
(void)dealloc {
[window release];
[super dealloc];
}
@end`
thanks
