Thank you for all your answers, I appreciate them.
Before you reply I think of my own solution which may not be as detailed and understood as vikingosegundo but it works and it can be extended.
Firstly from the check table I store the four numbers as a string to database. This allows me to store the formatting info with the "event". Each time i want to get the formatting i needed to get the string and change to array of numbers:
int option = 0;
unsigned int unitFlags = 0;
NSString *input = self.detailItem.prefs;
NSArray *myWords = [input componentsSeparatedByString:@","];
for (int fuu = 0; fuu < myWords.count; fuu++) {
option = [[myWords objectAtIndex:fuu]intValue];
switch (option)
{
case 0:
unitFlags = unitFlags | NSYearCalendarUnit;
break;
case 1:
unitFlags = unitFlags | NSMonthCalendarUnit;
break;
case 2:
unitFlags = unitFlags | NSWeekCalendarUnit;
break;
case 3:
unitFlags = unitFlags | NSDayCalendarUnit;
break;
case 4:
unitFlags = unitFlags | NSHourCalendarUnit;
break;
case 5:
unitFlags = unitFlags | NSMinuteCalendarUnit;
break;
}
}
As you can see I'm building my unit flag with units according to whats in the array.
Now some how i need to build the calendar, but how do i know whats are the components and the formatting?
Here is the answer:
NSString *prularity = @"";
if ([future compare:today] == NSOrderedAscending ) {
conversionInfo = [sysCalendar components:unitFlags fromDate:future toDate:today options:0];
untilOrSince = @"since";
} else {
conversionInfo = [sysCalendar components:unitFlags fromDate:today toDate:future options:0];
untilOrSince = @"until";
}
Here i build my calendar with the selected units, I also count from or to the date.
Finally I just need to do the format according to what was selected:
for (int fuu = 0; fuu < myWords.count; fuu++) {
option = [[myWords objectAtIndex:fuu]intValue];
switch (option)
{
case 0:
if ([conversionInfo year] >= 2 || [conversionInfo year] == 0) {
prularity = @"YEARS";
} else {
prularity = @"YEAR";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo year], prularity]];
break;
case 1:
if ([conversionInfo month] >= 2|| [conversionInfo month] == 0) {
prularity = @"MONTHS";
} else {
prularity = @"MONTH";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo month], prularity]];
break;
case 2:
if ([conversionInfo week] >= 2 || [conversionInfo week] == 0) {
prularity = @"WEEKS";
} else {
prularity = @"WEEK";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo week], prularity]];
break;
case 3:
if ([conversionInfo day] >= 2 || [conversionInfo day] == 0) {
prularity = @"DAYS";
} else {
prularity = @"DAY";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo day], prularity]];
break;
case 4:
if ([conversionInfo hour] >= 2 || [conversionInfo hour] == 0) {
prularity = @"HOURS";
} else {
prularity = @"HOUR";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo hour], prularity]];
break;
case 5:
if ([conversionInfo minute] >= 2 || [conversionInfo minute] == 0) {
prularity = @"MINUTES";
} else {
prularity = @"MINUTE";
}
one = [one stringByAppendingString:[NSString stringWithFormat:@"%ld %@ ", (long)[conversionInfo minute], prularity]];
break;
}
}
And print my counter :
one = [one stringByAppendingString:[NSString stringWithFormat:@" %@",untilOrSince]];
self.eventTimer.text = one;
Hope this will help someone with similar issue. I know this is not the best solution but so far it worked.
