Using custom uitableviewcells - ios

Question

I created custom cells for my table. Basically my cells have UIButton on them. I am reusing those cells.
However i have trouble with those buttons, because when cells is reused then all it's elements also is reused but i am seeking that these Button will be unique to every cells.
Maybe someone could propose a solution for this functionality ?

Answer 1

How about this if you have a property button on your custom cell?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath static NSString *CellIdentifier = #"My Cell Identifier";
MyCustomCellClass *cell = (MyCustomCellClass *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[MyCustomCellClass alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell
UIButton *myButtonForThisCell = [MyButtonArray objectAtIndex:indexPath.row];
cell.button = myButtonForThisCell;
return cell;
}

Answer 2

create a buttonView UIVIEW file with two methods as
-(NSInteger) getGridIndex
{
return gridIndex;
}
-(void) setGridIndex:(NSInteger)value
{
gridIndex = value;
}
Now in cellforrowatindexpath method
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryNone;
ButtonView *buttonView=[[ButtonView alloc] initWithFrame:CGRectMake(110, 110, 160, 26)];
buttonView.tag=18;
UIButton *button=[[UIButton alloc]initWithFrame:CGRectMake(55, 0, 60, 26)];
[button addTarget:self action:#selector(ButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[buttonView addSubview:button];
[cell addSubview:buttonView];
}
ButtonView *buttonView=(ButtonView*)[cell viewWithTag:18];
NSArray *d=[buttonView subviews];
UIButton *button=[d objectAtIndex:0];
//here you can change the setting or title of button or whatever u want to do.
[buttonView setGridIndex:indexPath.row];
}
Now in button action :
-(void)ButtonAction:(UIButton*)sender{
ButtonView *view = (ButtonView *)[sender superview];
NSInteger n=[view getGridIndex];
//here n is the indexpath.row at which the button was tapped..you can write its action accordingly.
}
