我正在分组表视图中做一个表单。在这种形式中,我有UIswitches和textfields。但在向下滚动后,细胞样式正在发生变化。
这是我的cellForRowAtIndex
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = nil;
    static NSString *MyIdentifier = @"GenericCell";
    cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
    }
        NSString *text = nil;
    if(indexPath.section == CREDENTIALS_SECTION){
        if (indexPath.row == 0) {
            NSLog(@"tot hier login");
            UITextField *login = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
            login.adjustsFontSizeToFitWidth = YES;
            login.placeholder = @"example@gmail.com";
            login.keyboardType = UIKeyboardTypeEmailAddress;
            login.returnKeyType = UIReturnKeyNext;
            login.backgroundColor = [UIColor clearColor];
            login.tag = 0;
            login.delegate = self;
            [login setEnabled: YES];
            [cell addSubview:login];
        }else if (indexPath.row == 1){
            NSLog(@"tot hier pass");
            UITextField *pass = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
            pass.adjustsFontSizeToFitWidth = YES;
            pass.placeholder = @"Required";
            pass.keyboardType = UIKeyboardTypeDefault;
            pass.returnKeyType = UIReturnKeyDone;
            pass.secureTextEntry = YES;
            pass.backgroundColor = [UIColor clearColor];
            pass.tag = 0;
            pass.delegate = self;
            [cell addSubview:pass];
        }
        if (indexPath.row == 0) { // Email
            text = @"Email";
        }
        else if(indexPath.row == 1) {
            text = @"Password";
        }
    }else  if(indexPath.section == METHODS_SECTION){
        UISwitch *toggleSwitch = [[UISwitch alloc]initWithFrame:CGRectMake(220, 10, 100, 30)];
        toggleSwitch.tag = indexPath.row;
        [toggleSwitch addTarget:self action:@selector(toggleSwitched:) forControlEvents:UIControlEventValueChanged];
        [cell addSubview:toggleSwitch];
        if (indexPath.row == 0) { // Web
            text = @"Web applicatie";
        }
        else if(indexPath.row == 1) { //Mobile
            text = @"Mobiele applicatie";
        }
        else if(indexPath.row == 2) { //Mail
            text = @"E-mail";
        }
    }else  if(indexPath.section == PHONE_SECTION){
        UITextField *phoneText = [[UITextField alloc] initWithFrame:CGRectMake(20, 10, 185, 30)];
        phoneText.adjustsFontSizeToFitWidth = YES;
        phoneText.font = [UIFont fontWithName:@"Arial-BoldMT" size:18];
        phoneText.keyboardType = UIKeyboardTypeNumberPad;
        phoneText.delegate = self;
        phoneText.textColor = [UIColor blackColor];
        phoneText.text = _person.phone;
        [cell addSubview:phoneText];
    }else  if(indexPath.section == REMARK_SECTION){
        UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(20, 10, 280, 260)];
        textView.text = _person.remark;
        textView.delegate = self;
        textView.font = [UIFont fontWithName:@"Arial" size:15.0];
        textView.backgroundColor = [UIColor clearColor];
        [cell addSubview:textView];
        text = @"";
    }else  if(indexPath.section == BUTTON_SECTION){
        cell.backgroundColor = [UIColor redColor];
        text = @"test";
    }
    cell.textLabel.text = text;
    return cell;
}经过一番搜索,我发现有更多的人有这个问题。问题就在这段代码中。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = nil;
    static NSString *MyIdentifier = @"GenericCell";
    cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
    }
        NSString *text = nil;但我找不到解决办法。希望有人能帮忙!
亲切的问候!
澄清
好了,这里你看到了我表格的截图。下面是一个红色的单元格(保存按钮),当我向下滚动时,其他的单元格会得到一个红色的背景。一些单元格,文本属性的变化。

最简单的解决办法是:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"GenericCell"] ;
    //some more code
    return cell;
}这将从表视图中删除可重用性,但是由于它是一个有限的设置视图,所以可以使用。我仍然建议从赫尔曼·克莱克的解决方案中拿出一两个。
