How can I change NSDateFormatter to "DD/MM/YYYY"? - iphone

Question

I have tried putting this:
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = [NSString stringWithFormat:#"DHSB Assignment: %#", Assignment1.text];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"M/d"];
event.startDate = [formatter dateFromString:dateField.text];
NSDateFormatter *formatter2 = [[NSDateFormatter alloc] init];
[formatter2 setDateFormat:#"M/d"];
event.endDate = [formatter2 dateFromString:dateField.text];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
[EKEventStore release];
NSLog(#"Successfully added '%#' to the calendar", Assignment1.text);
...but the event isn't added to the calendar if I enter a date in the format of "DD/MM/YYYY".
Why is this?
Thanks!

Answer 1

I think the correct format should be:
[formatter setDateFormat:#"dd/MM/yyyy"];
Try putting a NSLog on the dateFromString method to be sure you're getting the right result
EDIT: you may also need to set the correct locale for the date according to your needs.

I think your format string is wrong:
#"dd/MM/yyyy";
Might give better results.
By the way - what is the point of passing in an NSError* pointer to a function and not checking the return value or the error. Try replacing this line:
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
With something like this:
BOOL success = [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
if (!success) {
NSLog(#"Cannot save event. %#", [err localizedDescription];
}
Not perfect error checking but it will give you some idea of what is happening while you are developing.
