问题 I'd like to change the text from ¨Cancel¨to ¨Done¨ of the Cancel button inside the UISearchBar in iOS 8. I am using UISearchController. I've tried different approaches for iOS 6 and iOS 7 and they do not work. Has anybody done this? 回答1: Objective-C: [searchBar setValue:@"customString" forKey:@"_cancelButtonText"]; Swift: searchBar.setValue("customString", forKey:"_cancelButtonText") 回答2: This worked for me in ios8, did not try in ios7, but should do the trick, beware of placing this line in

问题 I'm trying to create custom scope buttons, but i'm having trouble actually linking them to my buttons. This is what I have extension HomeViewController: UISearchResultsUpdating { func updateSearchResults(for searchController: UISearchController) { let searchBar = searchController.searchBar let scope = titles[searchBar.selectedScopeButtonIndex] filterContentForSearchText(searchText: searchController.searchBar.text!, scope: scope) } } extension HomeViewController: UISearchBarDelegate { func

问题 I recently started to rewrite my iOS app to use the new UISearchController and a universal storyboard. My app is available for both devices ( iPhone and iPad ) so the change to the universal storyboard using the UISplitViewController was a big advantage. But sadly the UISearchController isn't working as expected. I added the UISearchController with the following lines: self.searchController = UISearchController(searchResultsController: nil) self.searchController.searchBar.sizeToFit() self

问题 I am having trouble using navigationItem.searchController in iOS 13. The search bar of the search controller is initially closed, but it won't collapse back after I scroll the table view. It 'bounces' back when I try to hide the bar. Also, the navigation bar turns white after the search bar appears. (The navigation bar has a custom tint color; see the attached screenshots.) Note that this wasn't the case in iOS < 13. Is this a bug in iOS 13? If it is, is there a work around to keep the tint

问题 I am using the UISearchController and the search function works except for two things. Perhaps they are related: a) The keyboard does not show. So I cannot press the "Search" button b) In my main TableView I access the prototype cell that has the style "Subtitle". When the search is going on, the cell that shows is "Basic" style. In both cases (TableViewController and SearchViewController) I use the same cell identifier. Any ideas? Here some of the code: class OverviewTableViewController:

问题 I made a view controller with a UISearchController and a UITableView . There are two different kind of search you can select from the search scope buttons : groups and people. Both searches work and show results on the table. However, if you click on each cell they should direct you to different dynamic pages (a dynamic group page or a dynamic person profile page). The one for groups works, while the one for profiles doesn't. Meaning whenever I click on the a person cell from the results that

It means, I can still typing, and I can see the results but, don't see
