在UITableView中添加数组首尾处的UIbutoton

先修改if条件句,

if ((lastSectionIndex == indexPath.section && lastRowIndex == indexPath.row ) || (indexPath.section == 0 && indexPath.row == 0 ))
{

然后就会这样：

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        UIButton *checkButton1 = [UIButton buttonWithType:UIButtonTypeCustom];
        checkButton1.tag = 100;//not recommended, I would suggest to use custom UITableViewCell class and add this button as subview inside its init method
        [checkButton1 setFrame:CGRectMake(200, 0, 168, 168)];
        [checkButton1 addTarget:self
                     action:@selector(customActionPressed:)
           forControlEvents:UIControlEventTouchDown];
        [checkButton1 setBackgroundImage:[[UIImage imageNamed:@"Up Arrow.jpg"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
        [cell addSubview:checkButton1]; 
    }

   //Adding a UIButton in last row
   NSInteger lastSectionIndex = [editTable numberOfSections] - 1;
   NSLog(@"lastSectionIndex:%d",lastSectionIndex);

   // Then grab the number of rows in the last section
   NSInteger lastRowIndex = [editTable numberOfRowsInSection:lastSectionIndex] - 1;
   NSLog(@"lastRowIndex:%d",lastRowIndex);

   // Now just construct the index path
   NSIndexPath *pathToLastRow = [NSIndexPath indexPathForRow:lastRowIndex inSection:lastSectionIndex];
   NSLog(@"last index:%@",pathToLastRow);

   UIButton *checkButton1 = (UIButton *)[cell viewWithTag:100];//not recommended, I would suggest to use custom UITableViewCell class and add this button as subview inside its init method
   if ((lastSectionIndex == indexPath.section && lastRowIndex == indexPath.row ) || (indexPath.section == 0 && indexPath.row == 0 ))
    {
       checkButton1.hidden = NO;
    } else {
       checkButton1.hidden = YES;
    }
