问题描述
我很难在UITableViewController的viewDidLoad方法中添加子视图（UIView）
I have difficulty adding a subview (UIView) from within the viewDidLoad method of a UITableViewController
这可行：
[self.view addSubview:self.progView];
但你可以通过UIView progView看到表格单元格出血。
But you can see the table cell lines bleed through the UIView progView.
我尝试过这种方法：
[self.view.superview insertSubview:self.progView aboveSubview:self.view];
这是尝试将progView，UIView添加到当前视图上方的superview。当我尝试这个时，UIView永远不会出现。
Which is an attempt to add the progView, UIView to the superview, above the current view. When I try this, the UIView never appears.
- 更新 -
以下是最新的尝试：
UIView *myProgView = (UIView *)self.progView; //progView is a method that returns a UIView
[self.tableView insertSubview:myProgView aboveSubview:self.tableView];
[self.tableView bringSubviewToFront:myProgView];
结果与[self.view addSubview：self.progView]相同; UIView出现但似乎在桌子后面。
Result is the same as [self.view addSubview:self.progView]; The UIView appears but seemingly behind the Table.
推荐答案
我尝试了上面的方法，但没有让它发挥作用。我还发现它需要太多的配置和代码，因为它需要从头开始设置表视图（这可以在故事板中轻松完成）。
I tried the approach above, but did not get it to work. I also found it to require too much configuration and code, since it requires setting up the table view from scratch (something that is easily done from within the storyboard).
，我添加了一个视图，我想将我的UITableView添加到UITableViewController的UINavigationController视图中，如下所示：
Instead, I added the view that I wanted to add above my UITableView into the UITableViewController's UINavigationController's view, as such:
[self.navigationController.view addSubview:<view to add above the table view>];
这种方法要求你在UINavigationController中嵌入UITableViewController，但即使你不想要导航控制器，你仍然可以使用这种方法，只需隐藏导航栏。
This approach requires that you have embedded the UITableViewController in a UINavigationController, but even if you do not want a navigation controller, you can still use this approach and just hide the navigation bar.
