     </Result>


    2012-09-19 ->Having 2 tables(i.e Table1,Table2)
    2013-09-20 ->Having 3 tables(i.e Table3,Table4,Table5)
    2013-09-21 ->Having 2 tables(i.e Table6,Table7)

现在我的问题是在上面的 xml 数据中我在 table1 中共有 7 个表，table2 数据属于 2012-09-19 日期。我想解析数据并在 View 中显示如下所示

                                  CreateBy  SalesDailyAmount  PurchasesDailyAmount
   2012-09-19 ->Want to display      1           100                0.0000

使用下面的代码

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
       attributes: (NSDictionary *)attributeDict
    {
         if( [elementName isEqualToString:@"CreateBy"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }
        if( [elementName isEqualToString:@"SalesDailyAmount"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }      
        if( [elementName isEqualToString:@"PurchasesDailyAmount"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }
    }
    -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
    {
        if( xmlResults )
        {
            [soapResults appendString: string];
             NSLog(@"soap result %@",soapResults);
             [arr_detail addObject:soapResults];
            NSLog(@"gg %@",arr_detail);
            NSLog(@"gcvxg %@",arr_info);
        }
        [tableView reloadData];
    }
    -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
    {
         if( [elementName isEqualToString:@"CreateBy"])
                {
                    xmlResults = FALSE;
                    [aslam4 addObject:soapResults];
                    NSLog(@"hello %@",aslam4);
                    soapResults = nil;
                }
                if( [elementName isEqualToString:@"SalesDailyAmount"])
                {
                    xmlResults = FALSE;
                    [aslam5 addObject:soapResults];            
                    NSLog(@"hello %@",aslam5);
                    soapResults = nil;
                }
              if( [elementName isEqualToString:@"PurchasesDailyAmount"])
                {
                    xmlResults = FALSE;
                    [aslam6 addObject:soapResults];
                      NSLog(@"hello %@",aslam6);
                    soapResults = nil;
                }
            }
    }

使用上面的代码我可以得到下面这样的数据

 OutPut
 CreateBy  SalesDailyAmount  PurchasesDailyAmount
     1           100                0.0000
     1           100                0.0000
     2           200                0.0000
     2           200                0.0000
     2           200                0.0000
     3           150                0.0000
     3           150                0.0000

但是我想在下面这样显示

        CreateBy  SalesDailyAmount  PurchasesDailyAmount
  2012-09-19 ->Want to display      1           100                0.0000
  2012-09-20 ->Want to display      2           200                0.0000
  2012-09-21 ->Want to display      3           150                0.0000

我不想显示多次。在 2012-09-19 有 2 个表，但都有相同的数据，但我不想显示多次。同样，2012-09-20 在这里也有 3 个表，我不想显示 3 次，我想在一行中显示 3 个表数据。总的来说我想说的是现在在数组中存储如下数据Array ={100,100,200,200,200,150,150} 但我不想这样 我想这样存储 Array ={100,200,150}请告诉我如何为此编写逻辑。

为了从数组中获取唯一值，请使用以下方法。

// Your array containing all values
NSArray *dataListArray = [[NSArray alloc] initWithObjects:@"100", @"100", @"200", @"200", @"200", @"300", @"300", @"300", nil];

// Array containing unique data.
NSArray *uniqueDataArray = [[NSSet setWithArray:dataListArray] allObjects];
