我写了一个 UITableView（我为演示硬编码了一些东西），有 20 行。我将删除按钮的文本更改为“删除”，默认为“删除”。我创建了两个按钮“顶部”和“底部”来将表格视图滚动到顶部和底部。当我滑动第 1 行时，会出现“删除”按钮。之后，我触摸底部按钮将表格视图滚动到底部。然后我触摸顶部按钮再次滚动到顶部。现在，我的删除按钮的文本更改为“删除”（默认）。你能帮我解决这个错误吗？

    [self.view addSubview:uitableView];

    goToTopButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
