iOS中TableView中的分页问题

Question

I have one tableview.In tableview each page there is 16 data.

For that I am calling one webservice

First I am passing Pagin Zero.

      [self callAPI:0];

-(void)callAPI:(int)page1{
   [dictParams setObject:[NSString stringWithFormat:@"%d",pagin]  forKey:@"pagin"];
 }

When I scrolldown new data is reloading.But when scroll up to tableview last data is not showing. Here is my code:

perPage = 16;

this is my code for paging

 - (void)scrollViewDidScroll:(UIScrollView *)scrollView
    {
    if(self.tblArticle.contentOffset.y >= (self.tblArticle.contentSize.height - self.tblArticle.bounds.size.height))
    {
        if(isPageRefreshing==NO){
            isPageRefreshing=YES;
            [self callAPI:perPage];
        }
    }
      else {
      }
    }

My requirement is first time pagin value is zero.Each time it will be pagin value + 16

when I scrollup I am not getting last data in tableview.

Can you help me to find out solution?

Answer 1

You have one array from which you fill tableview. So you have to insert every new data to that array.

eg, in success response of Api,

[yourArr addObjectFromArray:_responseArr]

• then reload tableview
