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.

问题 I am trying to create a dictionary type app with section header, title text, and subtitle text. I managed to get everything to work using the following code. The only thing I can't figure out is how to filter the UISearchBar to show the results of the String [Coptic] within the array. Is this even possible the way I organized everything or do I need to restructure? Does anyone have any suggestions? I left the code for the updateSearchResults blank on the bottom because I don't know what to

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'm having a problem getting a UISearchDisplay's text value to be set programatically on load of the view by another view and my question is have I overcomplicated my problem and missed something or am I on the right track of thinking. Here's the situation: I have a UITabBarController as my root view, there are 2 tabs, both have a UINavigationController setup so I can push views as needed. Tab 1 has a UITableViewController which is populated with a list of categories. Tab 2 has a MapView in

问题 Currently I am coding the search capability of a UISearchBar using data from a DB that's displayed in a table. I figure out the search results and save them to NSMutableArray *searchResults . Here's how that looks: - (void) searchGrapesTableView { [searchResult removeAllObjects]; numSearchWines=0; for (NSString *str in listOfWines) { NSRange titleResultsRange = [str rangeOfString:searchBar.text options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) { [searchResult addObject:str];
