Create Event with NSDate - iphone

Question

is there any way to create events for NSDate ? here is my code
NSDate *date = [NSDate date];
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:#"MMMM d, yyyy"];
NSString *dateStr = [dateFormatter stringFromDate:date];
myDate.text = dateStr;
for example if date = 12 FEB ;
myDate .text = #"Mother Day";
something like this

Answer 1

sure it is. You have to split the date into day and month using NSDateComponents
You could write a method like this:
- (BOOL)date:(NSDate *)date isSameAsDay:(NSInteger)day andMonth:(NSInteger)month {
NSUInteger dateFlags = NSDayCalendarUnit | NSMonthCalendarUnit;
NSDateComponents *components = [[NSCalendar currentCalendar] components:dateFlags fromDate:date];
if ([components day] == day && [components month] == month) {
return YES;
}
return NO;
}
and you would use it like this
if ([self date:[NSDate date] isSameAsDay:12 andMonth:2]) {
myDate.text = #"Mother Day";
}

Answer 2

This should do it:
NSDate *today = [NSDate date]; // Get ref to todays date
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *weekdayComponents =
[gregorian components:(NSWeekdayOrdinalCalendarUnit | NSWeekdayCalendarUnit | NSMonthCalendarUnit) fromDate:today];
NSInteger weekday = [weekdayComponents weekday]; // Sun == 1, Mon == 2, Tue...
NSInteger weekdayOrdinal = [weekdayComponents weekdayOrdinal]; // First weekday month == 1 etc...
NSInteger month = [weekdayComponents month];
NSLog (#"%i %i %i", weekday, weekdayOrdinal, month);
// Mothers day is every second Sunday of May so weekday == 1, weekdayOrdinal == 2, month == 5
if ((weekday == 1) && (weekdayOrdinal == 2) && (month == 5)) {
NSLog (#"It's mothers day!");
}
[gregorian release];
