EKEventStore saveEvent 一小时后添加事件

Question

我相信这以前有效，但现在当我在时区设置为自动或美国东部时间路易斯维尔时向我的日历添加一个事件，并且我添加一个美国东部时间的事件，它会将它添加到我的日历中提前一个小时。

我在另一个在 CST 中有活动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。是我的代码有误还是什么？

- (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
