你好 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一起放置。它正在重复行，当我开始编辑文本字段时，它不清除占位符它重写。而且我用开关还当我滚动第一行自动显示开关，我用在最后一行。whats错我的代码？ 这里是我的代码...Iphone中的分组表视图，带有一个部分
- (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.
