Question

I am using the following code to create an event within the iPhone’s calendar;

        EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
        event.title     = @"DHSB Assignment: %@", Assignment1.text;

        event.startDate = [[NSDate alloc] init];
        event.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];

        [event setCalendar:[eventStore defaultCalendarForNewEvents]];
        NSError *err;
        [eventStore saveEvent:event span:EKSpanThisEvent error:&err]; 
        [EKEventStore release];

        NSLog(@"Successfully added '%@' to the calendar", Assignment1.text);

Why is this saving an event with the name “DHSB Assignment: %@” rather than “DHSB Assignment: Example Text”?

Thank you.

Answer 1

event.title = [NSString stringWithFormat:@"DHSB Assignment: %@", Assignment1.text];

Your current code is equivalent to

[event setTitle:@"DHSB Assignment: %@"];
[Assignment1 text];

…which is valid, so it compiles and runs fine even though it isn’t doing what you want.
