- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"Categorycell";

    Categorycell *cell = (Categorycell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Categorycell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }
    [tableView setSeparatorColor:[UIColor clearColor]];
    cell.selectionStyle=UITableViewCellSelectionStyleNone;
cell.cell_btn.tag       = indexPath.row*10+1;

    [cell.cell_btn addTarget:self action:@selector(btnDown:) forControlEvents:UIControlEventTouchUpInside];

    cell.cell_ReadBtn.tag       =indexPath.row*10+1;
    [cell.cell_ReadBtn addTarget:self action:@selector(btnRead:) forControlEvents:UIControlEventTouchUpInside];

    cell.cell_Progress.tag= indexPath.row*10+1;

    if(!bIspress)
    {
    cell.cell_Progress.hidden=YES;
    }
    NSString *comicbook_id = [arr_comic_id objectAtIndex:indexPath.row];
    NSString  *filePath = [NSString stringWithFormat:@"book_%@.pdf",comicbook_id];
    NSLog(@"Book Name : %@",filePath);
    if(![appDelegate check_Book_available:filePath])
    {
        NSLog(@"Book Name Not : %@",filePath);
    cell.cell_ReadBtn.hidden=YES;
        cell.cell_btn.hidden= NO;
    }
    else
    {
        cell.cell_btn.hidden=YES;
        cell.cell_ReadBtn.hidden=NO;

    }
    cell.tag=indexPath.row*10+1;
    return cell;
}



-(void)btnDown:(UIButton*)sender
{
    NSLog(@"Called when press");


   // sender.hidden = YES;
    dlIndex = sender.tag/10;
    bIspress=true;
    NSLog(@"INDEX : %d : %d",dlIndex,[sender tag]);
// Categorycell *cell = (Categorycell *)[self.tbl_view dequeueReusableCellWithIdentifier:@"Categorycell"];

    NSString *str_id=[arr_comic_id objectAtIndex:dlIndex];

    dlCell = (Categorycell *)[[sender superview]superview];
    NSLog(@"INDEX progress : %d : Cell Tag : %d",dlCell.cell_Progress.tag,dlCell.tag);

     NSIndexPath *path = [tbl_view indexPathForCell:dlCell];
    if(dlCell.cell_Progress.tag==dlCell.cell_btn.tag)
    {

         [self Apicall_background];

    }

//    cell_Progressview = (UIProgressView* )[dlCell.contentView viewWithTag:dlIndex*10+1];
//    cell_Progressview.hidden = NO;




}

Answer 1

试试这个

-(void)btnDown:(UIButton*)sender
{

     //your code

     if(dlCell.cell_Progress.tag==dlCell.cell_btn.tag)
     {

          [self Apicall_background];
          CGPoint center = CGPointMake(CGRectGetMidX(dlCell.bounds),
                                       CGRectGetMidY(dlCell.bounds));


          dlCell.cell_Progress.center = center;

     }
}
