この NSTimer を 45 分後に停止したいのですが、停止しません。私は何を間違っていますか?
TIMER_COUNT = 45
HOURS_IN_HOURS = 60
HOURS_IN_DAY = 24
- (void)start
{
self.timerCountdown = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateCountdown) userInfo:nil repeats: YES];
}
- (void)stop
{
[self.timerCountdown invalidate];
self.timerCountdown = nil;
}
- (void)updateCountdown
{
NSDate *currentDate = [NSDate date];
NSDate *finalTime = [currentDate dateByAddingTimeInterval:(TIMER_COUNT * HOURS_IN_HOUR)];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *componentsHours = [calendar components:NSHourCalendarUnit fromDate:currentDate];
NSDateComponents *componentMinuts = [calendar components:NSMinuteCalendarUnit fromDate:currentDate];
NSDateComponents *componentSeconds = [calendar components:NSSecondCalendarUnit fromDate:currentDate];
NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *componentsDaysDiff = [gregorianCalendar components:NSDayCalendarUnit
fromDate:currentDate
toDate:finalTime
options:0];
NSLog(@"%20d Days, %02d Hours, %02d Minutes, %02d Seconds.", componentsDaysDiff.day, HOURS_IN_DAY - componentsHours.hour, HOURS_IN_HOUR - componentMinuts.minute, HOURS_IN_HOUR - componentSeconds.second);
if ([currentDate compare:finalTime] == NSOrderedSame)
{
NSLog(@"Done.");
[self stop];
}
}
前もって感謝します。
