【问题描述】：

我在表格视图单元格上使用自定义 UIImageView 和 UITextField。一切正常，但是当我选择任何单元格时，imageview 会被隐藏，但 textfield 会显示。那么问题是什么，我该如何解决呢？

这是我在 tableview 上使用图像和文本字段的代码 -

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    static NSString *cellidentitifier = @"cell";
    UITableViewCell * cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentitifier];
    if (cell ==nil)
    
        cell = [tableView dequeueReusableCellWithIdentifier:cellidentitifier];

    
    else
    
        [cell prepareForReuse];
    

    UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(30, 10, 68, 70)];
    imgview.backgroundColor = [UIColor blackColor];
    imgview.userInteractionEnabled = NO;
    imgview.layer.cornerRadius =YES;
    [cell.contentView addSubview:imgview];

    _nameTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 10, 160, 20)];
    _nameTF.placeholder =@"Name";
    _nameTF.layer.borderWidth = 1.0;
    [cell.contentView addSubview:_nameTF];
    _nameTF.delegate = self;
    _nameTF.userInteractionEnabled = NO;
    _nameTF = nil;

    _addressTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 34, 160, 20)];
    _addressTF.placeholder = @"Address";
    _addressTF.layer.borderWidth= 1.0;
    [cell.contentView addSubview:_addressTF];
    _addressTF.delegate = self;
    _addressTF.userInteractionEnabled = NO;
    _addressTF = nil;


    _PhoneTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 58, 160, 20)];
    _PhoneTF.placeholder = @"Phone";
    _PhoneTF.layer.borderWidth= 1.0;
    [cell.contentView addSubview:_PhoneTF];
    _PhoneTF.delegate = self;
    _PhoneTF.userInteractionEnabled = NO;
    _PhoneTF = nil;

    _slotTF = [[UITextField alloc]initWithFrame:CGRectMake(30, 84, 250, 18)];
    _slotTF.placeholder = @"Slot";
    _slotTF.layer.borderWidth= 1.0;
    [cell.contentView addSubview:_slotTF];
    _slotTF.delegate = self;
    _slotTF.userInteractionEnabled = NO;
    _slotTF = nil;

    return cell;

【参考方案1】：

试试这个

 UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(30, 10, 68, 70)];
    imgview.backgroundColor = [UIColor blackColor];
    imgview.layer.borderWidth = 1.0;
    imgview.userInteractionEnabled = NO;
    imgview.layer.cornerRadius =YES;
    [cell.contentView addSubview:imgview];

然后你选择了一个单元格，你发现imgview还在 因此，我认为选择一个单元格时，此单元格的背景颜色变为gray.so，覆盖了IMGView的BlackColor。它不是隐藏的
