Compare hours and minutes to current time

I receive two strings: "from"="12:30" and "to"="14:30" which are two NSString objects. I'd like to check if the current time is between the two received ones. What's the best way to do this? Thanks.

The 2nd solution as proposed by Aravindhanarvi could look like the following ...

NSString *time1 = @"12:30";
NSString *time2 = @"14:30";

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"HH:mm";
// ignore time zone of device
formatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0]; 

NSDate *date1 = [formatter dateFromString:time1];
NSDate *date2 = [formatter dateFromString:time2];
NSDate *now   = [NSDate date];

BOOL inBetween = ([now compare:date1] == NSOrderedDescending 
               && [now compare:date2] == NSOrderedAscending);

Get the hours/minutes components from the input date:

NSCalendar *gregorianCal = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dataComps = [gregorianCal components: (NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:yourDate];

NSInteger minutes = [dateComps minute];
NSInteger hours = [dateComps hour];

Then split the time string and compare the minutes and hours. Another way is to convert the strings to NSDates and compare the dates.

- (BOOL)date:(NSDate*)date isBetweenDate:(NSDate*)beginDate andDate:(NSDate*)endDate
{
    if ([date compare:beginDate] == NSOrderedAscending)
        return NO;

    if ([date compare:endDate] == NSOrderedDescending) 
        return NO;

    return YES;
}
