这是我用于在navigationBar中增加一天的方法,并将当天的名称设置为标题.我知道这是错的,因为我每次调用时都设置"今天"变量.但是每次调用这种方法时我都无法弄清楚如何增加+1天.

-(void)stepToNextDay:(id)sender
{
    today = [NSDate date];
    NSDate *datePlusOneDay = [today dateByAddibgTimeInterval:(60 * 60 * 24)];
    NSDateFormatter *dateformatterBehaviour = [[[NSDateFormatter alloc]init]autorelease];
    [dateFormatter setDateFormat:@"EEEE"];
    NSString *dateString = [dateFormatter stringFromDate:datePlusOneDay];
    self.navigationItem.title = datestring;
}

我试图用批量插入或其他更有效的方法解决这段代码,但我没有想法.你会怎么解决这个问题.而不是循环这么多次我想在几次调用中更有效.请告诉我你会怎么做？尽可能使用代码!感谢名单
