I want to reduce the count down of the time. So If the user minimize app then app loading the background. How can run the timer in application background? I am using the below code. When app is minimized timer is stopped. Please help me.
timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(timerCountDown) userInfo:nil repeats:YES];
- (void)timerCountDown
{
if(secondsLeft > 0 ) {
secondsLeft -- ;
hours = secondsLeft / 3600;
minutes = (secondsLeft % 3600) / 60;
seconds = (secondsLeft %3600) % 60;
}
}
