ios - 以编程方式将文本字段添加到uitableviewcell不起作用

Question

新秀ios的问题.我正在尝试使用表视图控制器创建一个注册表单.我正在尝试在cellForRowAtIndexPath方法中以编程方式向每个单元格添加文本字段,但我的所有文本字段似乎都在第一个单元格上创建 - 一个与另一个单元格重叠.这是我的代码.

这是我的细胞渲染方式.我认为我正在做一些愚蠢的事情,重复使用细胞.我确实在stackoverflow上检查了一些其他类似的线程,但没有一个帮助.你能告诉我我错过了什么,或者这是否应该是这样做的.您的意见非常感谢.

谢谢,迈克

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

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"signUpFields" forIndexPath:indexPath];

// Configure the cell...
if (indexPath.row == 0){
    //self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(5, 0, 280, 21)];
    self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
    self.firstName.placeholder = @"First Name";
    self.firstName.autocorrectionType = UITextAutocorrectionTypeNo;
    [self.firstName setClearButtonMode:UITextFieldViewModeWhileEditing];
    //cell.accessoryView = self.firstName;
    [cell.contentView addSubview:self.firstName];

试试这个..

     - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *CellIdentifier = @"Cell";
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        }

       if (indexPath.row == 0){
    //self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(5, 0, 280, 21)];
    self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
    self.firstName.placeholder = @"First Name";
    self.firstName.autocorrectionType = UITextAutocorrectionTypeNo;
    [self.firstName setClearButtonMode:UITextFieldViewModeWhileEditing];
    //cell.accessoryView = self.firstName;
    [cell addSubview:self.firstName];
}

if (indexPath.row == 1){
    self.lastName = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
    self.lastName.placeholder = @"Last Name";
    self.lastName.autocorrectionType = UITextAutocorrectionTypeNo;
    [self.lastName setClearButtonMode:UITextFieldViewModeWhileEditing];
    //cell.accessoryView = self.lastName;
    [cell addSubview:self.lastName];
}

if (indexPath.row == 2){
    self.emailId = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
    self.emailId.placeholder = @"Email Id";
    self.emailId.autocorrectionType = UITextAutocorrectionTypeNo;
    [self.emailId setClearButtonMode:UITextFieldViewModeWhileEditing];
    //cell.accessoryView = self.emailId;
    [cell addSubview:self.emailId];
}

if (indexPath.row == 3){
    self.password = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
    self.password.placeholder = @"Password";
    self.password.secureTextEntry = YES;
    self.password.autocorrectionType = UITextAutocorrectionTypeNo;
    [self.password setClearButtonMode:UITextFieldViewModeWhileEditing];
    //cell.accessoryView = self.password;
    [cell addSubview:self.password];
}

self.firstName.delegate = self;
self.lastName.delegate = self;
self.emailId.delegate = self;
self.password.delegate = self;


cell.selectionStyle = UITableViewCellSelectionStyleNone;

        return cell;
    }

无需在表视图中再次添加文本视图,这是错误的.试试这个,这对你有用,但更好的是你应该创建一个自定义Cell并使用.这是最好的方法,因为你可以使用你想要的任何Cell.
