我被建议为每个部分创建多个子类，因为我正在创建一个包含许多不同内容的表视图，问题是无论我做什么，它都会随机地复制每个单元格的内容。我做错了什么？
identifier0 = @"Cell0";
identifier1 = @"Cell1";
identifier2 = @"Cell2";
[self.tableView registerClass:[accountTableViewCell class] forCellReuseIdentifier:identifier0];
[self.tableView registerClass:[NotificationTableViewCell class] forCellReuseIdentifier:identifier1];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//section 0
self.emailTextField.delegate = self;
self.cellName = [[UILabel alloc] initWithFrame:CGRectMake(20, 12, 130, 20)];
self.cellName.textColor = [UIColor colorWithRed:0.137 green:0.145 blue:0.157 alpha:1];

{

答案 0 :(得分：0)
您看到重复内容，因为您将自定义contentView的子视图作为UITableViewDataSource的属性。例如，你对第0节中的每个单元使用self.cellName。假设你在第0节中有5个cellName类型的单元格。如果你想在所有5个单元格上有一个自定义UILabel，那么你需要分配/ init 5单独的UILabel对于每个单元格，关键部分是每个标签需要5个单独的指针。现在你使用的是self.nameLabel。有很多方法可以解决这个问题。一种方法是将自定义子视图作为两个UITableViewCell子类的属性。
