我为我的桌子创建了自定义单元格。基本上我的细胞上有UIButton。我正在重复使用那些细胞。
但是我对这些按钮有困难,因为当重复使用单元格时,它的所有元素也会重复使用,但我希望这些按钮对每个单元都是唯一的。
也许有人可以为此功能提出解决方案?

如果您的自定义单元格中有属性button
,那该怎么办?
- (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;
}

使用两种方法
创建一个buttonView UIVIEW文件-(NSInteger) getGridIndex
{
return gridIndex;
}
-(void) setGridIndex:(NSInteger)value
{
gridIndex = value;
}
现在使用cellforrowatindexpath方法
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];
}
现在按钮操作:
-(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.
}
