Ios 如果在不可见的情况下旋转，UISearchController的搜索栏将被分离并与TableView重叠

所以我有一个带UISearchController的UITableView。它加载良好，然后我进行搜索并选择结果，将新的视图控制器推送到我的UINavigationController

如果，当新的VC出现在屏幕上时，我旋转我的手机，然后旋转回去，然后再返回…当我回到UITableView时，UISearchBar就不见了。如果要进行故障排除，我隐藏了UINavigationBar，或者查看了视图层次结构，我发现它已上移到导航栏后面并被覆盖

我尝试过各种各样的黑客解决方案，比如在完成加载后移动酒吧的框架，但都没有成功。在这件事上我真的需要帮助，我被难住了。我在谷歌上找到的东西都没有帮助

以下是before、after和view Hierarchy的屏幕截图：

以下是所有与视图相关的代码：

- (void)viewDidLoad {
[super viewDidLoad];


if (!self.title)
    self.title = @"GLOBAL SEARCH";

self.tableView.backgroundColor = [UIColor whiteColor];

//TESTING
//if I don't have this, the bar detaches from the navigation bar
self.edgesForExtendedLayout = UIRectEdgeAll;
self.extendedLayoutIncludesOpaqueBars = YES;
//test


self.definesPresentationContext = YES;

self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchResultsUpdater = self;
self.searchController.delegate = self;
self.searchController.searchBar.frame = CGRectMake(self.searchController.searchBar.frame.origin.x,
                                                   self.searchController.searchBar.frame.origin.y,
                                                   self.searchController.searchBar.frame.size.width,
                                                   44.0);


self.searchController.searchBar.backgroundImage = [[UIImage alloc] init];
self.searchController.searchBar.backgroundColor = kConstantBaseColor;
self.searchController.searchBar.barTintColor = kConstantBaseColor;
self.searchController.searchBar.tintColor = kConstantLabelColor;

 //set color
 [[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setDefaultTextAttributes:@{NSForegroundColorAttributeName:kConstantLabelColor}];


self.searchController.hidesNavigationBarDuringPresentation = NO;
[self.searchController.searchBar setSearchBarStyle:UISearchBarStyleMinimal];
self.tableView.tableHeaderView = self.searchController.searchBar;
self.tableView.clipsToBounds = NO;
self.tableView.tableHeaderView.clipsToBounds = NO;
self.tableView.tableHeaderView.backgroundColor = kConstantBaseColor;

 //put purple block above, in case user scrolls up
CGRect bufferFrame = CGRectMake(self.searchController.searchBar.frame.origin.x,
                                self.searchController.searchBar.frame.origin.y-300,
                                self.searchController.searchBar.frame.size.width*2,
                                300);
UIView *purpleBuffer = [[UIView alloc] initWithFrame:bufferFrame];
purpleBuffer.backgroundColor = kConstantBaseColor;
[self.tableView addSubview:purpleBuffer];
}


- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
[super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];

[coordinator animateAlongsideTransition:nil completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {

}];  
 }

有人有什么解决办法吗？我被难住了，好几天来我一直在用头撞它。非常感谢。
