因此，与其添加我使用过的24小时时间间隔..

So rather than adding a time interval of 24 hours I have used ..

+ (NSDate *) addOneDayToDate: (NSDate *) date {
   return [currentCalendar dateByAddingComponents:oneDay toDate:date options:0];
}

其中

 oneDay = [[NSDateComponents alloc] init];
 [oneDay setDay:1];
 currentCalendar = [NSCalendar currentCalendar];

在大多数情况下，这是可行的，除非日期在午夜到时钟通常在凌晨2:00之间更改的时间.不需要逻辑，因为日期时间将在此之后.

This works in most cases unless the date is between midnight and the time the clocks change usually around 2:00am. Have not needed logic for this since the date times will be after this.
