我想检查日期，并得到前天、昨天、今天、明天4种格式的结果

我有一个日期，我想将该日期与当前日期进行比较

现在我已经这样做了，但这只是给我一个正数的日子，所以我不能得到的日期已经过去了，或者它仍然会来的日期

-(void)getDateDiffrenceForBirthday:(NSString *)strOriginalDate  

{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
    NSDate *originalDate = [formatter dateFromString:strOriginalDate];

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *components = [calendar components:NSDayCalendarUnit
                                               fromDate:originalDate
                                                 toDate:[NSDate date]
                                                options:0];

    NSLog(@"Days To Go %d",components.day);

}

您可以尝试以下代码来获取日期差异

-(void)getDateDiffrenceForBirthday:(NSString *)strOriginalDate  

{
    NSDate *originalDate = [formatter dateFromString:strOriginalDate];
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSUInteger unitFlags = NSDayCalendarUnit;
    NSDateComponents *components = [gregorian components:unitFlags fromDate:originalDate toDate:[NSDate date] options:0];

    NSLog(@"Days To Go %d",[components day]+1);

}

您可以使用此功能。其参数日期格式如下：

如果日期是明天、今天、昨天、前天，则返回相应的文本

如果日期早于一周，则返回周日、日和月

所有其他日期格式为中等样式
