Question

我已经通过代码在应用程序中进行了注册，但如果我向上和向下滚动不可见的单元格会被其他单元格的设置覆盖......有没有人经历过这样的事情？我很确定我错过了一些配置，但我不知道哪个。

这是我的代码。它的代码很多......对不起。但我真的不知道从哪里开始

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (section == 0) {
        return 4;
    } else if (section == 1) {
        return 4;
    } else {
        return 5;
    }
}

    return 3;

    } else  {

    }

}

为单元格使用不同的标识符：

static NSString *CellIdentifier = @"anmeldenCell";

或为他们准备重置功能。</ p>

您的问题是细胞在各部分之间重复使用。你在这里添加子视图[cell.contentView addSubview：gender];并且你永远不会删除它 - 所以它将被添加到同一个单元格+这个视图的单元格也将被用于其他部分。

最佳方法是为每个部分准备自定义单元格，并为它们使用不同的CellIdentifier。此外，当您重复使用它们时，可以正确地查看它，而不是多次添加子视图。

顺便说一句。使用枚举来增加可读性，而不是1,2,3,4使用kSectionMyProfile等...

表视图中不可见的单元格被覆盖
