推荐答案

通常情况下，您不会以这种方式隐藏它.相反，您应该尝试根本不显示它.在您的表视图控制器的 numberOfRowsInSection 方法中，尝试如下操作:

Normally, you wouldn't hide it this way. Rather, you should try not displaying it at all. In your table view controller's numberOfRowsInSection method, try something like this:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    //... code regarding other sections goes here

    if (section == 1) { // "1" is the section I want to hide
        if (self.cellShouldBeVisible) {
            return 0; // show no cells
        } else {
            return 1; // show one cell
        }
    }
}

(当然你可以用你自己的代码替换 self.cellShouldBeVisible)

(you can replace self.cellShouldBeVisible with your own code of course)

如果您想从显示单元格变为不显示单元格，请将 self.cellShouldBeVisible 设置为所需的 BOOL 值并调用 [self.tableView reloadData];

If you want to go from displaying to not displaying the cell, set self.cellShouldBeVisible to the desired BOOL value and call [self.tableView reloadData];
