I have added a UISearchController to my code using the following method:
我使用以下方法将UISearchController添加到我的代码中:
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.scopeButtonTitles = @[];
self.searchController.searchBar.delegate = self;
self.tableView.tableHeaderView = self.searchController.searchBar;
[self.searchController.searchBar sizeToFit];
self.definesPresentationContext = YES;
This creates my search controller and adds it to the top of my tableView. Annoyingly it starts visible though:
这将创建我的搜索控制器并将其添加到我的tableView顶部。令人讨厌的是它开始可见:
I can hide it by sliding it up under the navigation bar which suggests the underlying functionality of the code is working but I can't get it to start hidden so I can slide it down.
我可以通过在导航栏下滑动来隐藏它,这表明代码的基本功能正在运行,但我无法让它开始隐藏,所以我可以将其滑下来。
I have tried adjusting the edge insets, I have tried setting the navigation bar to translucent, I have tried to go through the search bar tutorials online but nothing seems to be dealing with this issue.
我已经尝试调整边缘插图,我已经尝试将导航栏设置为半透明,我已经尝试通过在线搜索栏教程但似乎没有处理这个问题。
Any help very welcome
