您好 我正在使用分组tableview来填充文本字段中的条目。我使用一节和9行。 并将一个标签和文本字段与占位符放在一起。它是重复的行，当我开始编辑文本字段时，它不清除占位符它是否覆盖。我也使用开关当我滚动第一行自动显示我在最后一行使用的开关。我的代码错了什么??? 这是我的代码......
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 9;
}
// Customize the appearance of table view cells.
