Make UISearchController search bar automatically active

那年仲夏 提交于 2019-12-04 03:41:05
I've implemented a UISearchController with its search bar in a navigatiom bar and I would like to make the search bar active when the view is loaded. When I say active, I mean that the keyboard appears and the user can type his/her search without tap the search bar. I initialised the UISearchController with the following code: - (void)viewDidLoad { self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil]; [self.searchController setSearchResultsUpdater:self]; [self.searchController setDimsBackgroundDuringPresentation:NO]; [self.searchController

UISearchBar cancel button not responding

情到浓时终转凉″ 提交于 2019-12-04 03:33:35
I have implemented searchbar which shows cancel button once user has focus in searchbar. For this I have written searchBar.showsCancelButton = YES; in my searchBarTextDidBeginEditing method. In searchBarSearchButtonClicked , I resign the keyboard so that user can view full tableview. Problem: At this point the searchbar cancel button is not responding. It only responds once searchbar gets focus again. Is this the default property of search bars cancel button or am I missing something in my code. I want to use cancel button without giving the focus in searchbar again. This is search bar cancel

Hide empty cells in UITableView

跟風遠走 提交于 2019-12-04 00:26:36
问题 I have a searchable tableview, but would like to only display the number of cells that are returned once a user starts a search. For instance, if a user types in a charecter and there is only one cell that matches the search, the remaining cells the remaining cells of the table are empty. I was wondering if there is a way to hide those empty cells. I was also wondering if there is a way to hide the table view if a person's search does not match any data (by default, it displays a table of

Custom UISearchController Animation

假装没事ソ 提交于 2019-12-04 00:09:11
问题 The Bottom Line Question: How do I override the default animation for the dismissal of a searchBar belonging to a UISearchController? Standard Search Controller Behavior: Okay so I am trying to create a custom animation for when the UISearchBar that is attached to a UISearchController becomes active. It seems the standard animation expects for the searchBar to begin with a width that takes up the screen. When the animation begins it shrinks the searchBar and fades in a cancel button to the

UISearchBar - what is “search results button” for?

依然范特西╮ 提交于 2019-12-03 23:32:21
(Duplicate of this question , but I figured I could try again, since that one wasn't answered...) The UISearchBar on the iPhone has an option showsSearchResultsButton. When you turn it on, it shows a button with horizontal lines inside the search bar, and you can implement a callback that will be called when the user presses it. The thing is, I can't find a single place on the Internet where it says what the intended purpose of this button is. I know I could make it do anything, but I'd like to know what it's actually for. Should it show a history of searches, or all items without filtering,
