ios - 自定义单元格文本字段索引在滚动时发生变化

Question

我在自定义单元格中有一个 UITextField。一旦我在第一个和第二个单元格中输入了值，并且当我滚动 UITableView 文本字段索引正在更改(第一个单元格值更改为最后一个单元格)。谁能帮我解决我的问题？

这是我的代码:

static NSString *cellIdentifier = @"TableCellID";

CustomTableViewCell *cell = (CustomTableViewCell *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil) {        
    cell = [[CustomTableViewCell alloc] init]; // or your custom initialization
}

cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;

cell.txt_TCelltext.tag=indexPath.row;
cell.txt_TCelltext.placeholder=@"0.00";

[cell.txt_TCelltext setDelegate:self];

这是因为细胞复用。尝试从字典(或)数组填充 UITextField 数据。试试这个:

- (UITableViewCell *)tableView:(UITableView *)tableViewLocal
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Your Code

    UITextField *textField = [[UITextField alloc]init];
    textField.delegate = self;
    textField.tag = indexPath.row;

    if ([myTextFieldDictionary objectForKey:[NSString stringWithFormat:@"%ld", (long)textField.tag]])
    {
        textField.text = [[myTextFieldDictionary objectForKey:[NSString stringWithFormat:@"%ld", (long)textField.tag]];
    }
}

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    [myTextFieldDictionary setValue:textField.text
                             forKey:[NSString stringWithFormat:@"%ld", (long)textField.tag]];    
}
