Question

我使用以下代码在iPhone的日历中创建一个事件;

        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);

为什么这个名称为“DHSB Assignment：％@”的事件而不是“DHSB Assignment：Example Text”？

谢谢。

Answer 1

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

您当前的代码相当于

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

...这是有效的，所以它编译并运行正常，即使它没有做你想要的。

为什么我不能编写EKEvent标题？
