我很难在UITableViewController的viewDidLoad方法中添加子视图(UIView)

这有效:

[self.view addSubview:self.progView];

但是你可以通过UIView progView看到表格单元格出血.

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.

- 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.

我对 React Native 并不陌生，已经研究这个问题有一段时间了，但我现在面临的问题几乎是新的。我厌倦了这个问题。我面临的问题是，我无法在 iOS 模拟器上运行该应用程序。我几乎尝试了所有方法来解决这个问题，但都无法解决。

我的考验：

1. 删除Pods然后Podfile.lock做pod install然后react-native run-ios
2. 删除node_modules然后package-lock.json然后Pods，Podfile.lock然后做npm install-> pod install->react-native run-ios
3. 打开 Xcode，清理 Build，然后react-native run-ios
4. 运行react-native start --reset-cache然后react-native run-ios
5. 做pod update然后react-native run-ios

它仍然失败，并且在控制台上抛出了很多错误。我对这种情况感到困惑和恐惧。直到早上一切都工作正常，但现在什么都不起作用了

我得到的错误：
