EKEventStore saveEvent 一小时后添加事件

Question

我相信这在以前有效，但现在当我在时区设置为自动或路易斯维尔（美国东部时间）时将事件添加到我的日历时，我添加了一个美国东部时间的事件，它会提前一小时将它添加到我的日历中.

我在另一个在 CST 中有事件的应用程序上执行此操作，当我将它们添加到我的日历时，它会很好地添加它们。是我的代码错了吗？

- (void)viewWillAppear:(BOOL)animated {
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setTimeZone:[NSTimeZone timeZoneWithName:self.event.timeZone]];
    [dateFormat setDateFormat:@"yyyy-MM-ddHH:mm:ss"];

    self.startDate = [dateFormat dateFromString:self.game.dateTime];
    self.endDate = [[NSDate alloc] initWithTimeInterval:60*self.event.gameDuration sinceDate:self.startDate];
}


    - (void) addToCalendar
    {
        EKEventStore *eventStore = [[EKEventStore alloc] init];

        if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]){
            [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
             {
                 for (EKSource *source in eventStore.sources)
                 {
                     if (source.sourceType == EKSourceTypeCalDAV || source.sourceType == EKSourceTypeLocal)
                     {

                         EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
                         event.title     = [NSString stringWithFormat:@"%@ vs. %@", self.game.awayTeam.team.name, self.game.homeTeam.team.name];
                         event.location = [NSString stringWithFormat:@"%@ - %@", self.game.venue.name, self.game.venue.court];

                         event.startDate = self.startDate;
                         event.endDate = self.endDate;

                         [event setCalendar:[eventStore defaultCalendarForNewEvents]];
                         NSError *err;

                         [eventStore saveEvent:event span:EKSpanThisEvent error:&err];

                         if(err) {
                             dispatch_async(dispatch_get_main_queue(), ^{
                                 [self showAlert:@"Error" desc:@"There was a problem adding this game to your calendar"];
                             });
                         }
                         else {
                             dispatch_async(dispatch_get_main_queue(), ^{
                                 [self showAlert:@"Success" desc:@"Game added to your calendar"];
                             });
                         }
                         break;
                     }
                 }
             }];

        }
    }

我发现 Apple 使用他们自己的时区字符串，所以我只是在通过我们的 API 发送时将 Windows 时区转换为 Apple。
