uilocalnotification is not firing at exact time

Question

I want to implement uilocalnotification in my app. but the problem is that it is not firing at the exact time. it is firing after 30 - 40 secs from the given fi

Answer 1

You can set fireDate by using NSDateComponents, in which you can set seconds for firedate. When I set it to 0 doesn't work, but it works if I set it to 1 seconds. 1 second late will be OK compared to 30-40 seconds.

NSCalendar *cal = [NSCalendar currentCalendar];
    NSDateComponents *dateComps = [cal components:NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay |NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond   fromDate:fireDate];
    [dateComps setSecond:1];
    [dateComps setNanosecond:00];
    NSDate *newDate = [cal dateFromComponents:dateComps];
    fireDate = newDate;
