dd我在 Native CALENDAR 中创建事件时遇到问题，当我传递event.startDate除了当前时间戳之外的任何内容时......还有event.endDate不能使用不同的值，如下所示..
- (void)createEventInCalendar:(NSString *)calendarType withTitle:(NSString *)eventTitle startDate:(NSString *)stDate endDate:(NSString *)endDATE withNotes:(NSString *)paramNotes addAlarm:(BOOL)alarmNeeded {
EKEventStore *eventStore = [[EKEventStore alloc] init];
/* Are there any calendars available to the event store? */
if ([eventStore.calendars count] == 0){
NSLog(@"No calendars are found.");
}
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = [NSString stringWithFormat:@"%@ with Alarm", eventTitle];
//Convert String to DATE
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd HH:mm:SS"];
NSDate* date1 = [dateFormat dateFromString:stDate];
NSDate* date2 = [dateFormat dateFromString:endDATE];
//get Difference betwenn 2 DATE Values
NSTimeInterval distanceBetweenDates = [date1 timeIntervalSinceDate:date2];
event.startDate = date1;
event.endDate = [date1 initWithTimeInterval:distanceBetweenDates sinceDate:event.startDate];
event.notes = paramNotes;
/* The alarm goes off 2 seconds before the event happens */
EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:-2.0f];
[event addAlarm:alarm];
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];
NSLog(@"Error shows: %@", err);
//Show EVENT EDIT Screen to User.
EKEventEditViewController *controller = [[EKEventEditViewController alloc] init];
controller.eventStore = eventStore;
controller.event = event;
controller.editViewDelegate = self;
[self presentModalViewController:controller animated:YES];
}
调试后：Error Domain=EKErrorDomain Code=4 "开始日期必须早于结束日期。" UserInfo=0x223170 {NSLocalizedDescription=开始日期必须早于结束日期。}
我的日志在哪里：ST 日期：2013-04-25 07:50:00 和结束日期：2013-04-29 07:50:00
但 EVENT EDIT View 在 START DATE 之前的某个时间显示 END DATE 值。这很奇怪。
谁能指导我如何解决它？谢谢。
