uisearchbar

问题 I have a UITableViewController subclass, displayed in a modal view on an iPad. The view controller has a UISearchDisplayController subclass with a UISearchBar included in the header view of the table. The subclassed UISearchDisplayController is called NoAnimationSearchDisplayController and I have overridden the - (void)setActive:(BOOL)visible animated:(BOOL)animated method to prevent the search bar from animating into the navigation bar when it's set to active. The method override is below...

问题 i creating a search bar which should behave like iPhones contact search bar.currently it does partially. here is my code -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { NSRange whiteSpaceRange = [result rangeOfCharacterFromSet:[NSCharacterSet whitespaceCharacterSet]]; if (whiteSpaceRange.location != NSNotFound) { NSString * stringAfterSpace = [result substringFromIndex:whiteSpaceRange.location]; NSString *

问题 In iOS 11 height of UISearch bar has increased , but I want the same height as in iOS 10. How to do that ? I am using below code to create the searchController. searchController = UIUtils.searchControllerInitialize(self) searchController.searchResultsUpdater = self searchController.delegate = self searchController.searchBar.delegate = self viewTemp = UIView(frame: CGRect(x: 0.0, y: 64.0,width: UIScreen.main.bounds.size.width , height: 44)) viewTemp.addSubview(self.searchController.searchBar)

问题 Hi can I remove clear button (X button)present in UISearchBar? I didn't find any delegate for that. There is one for cancel button. Thanks 回答1: You can not directly access the clearButton of UISearchBar . You have to loop through the subviews of the UISearchBar to find the UITextField , and set its clearButtonMode property to UITextFieldViewModeNever . Note: This is not a permanent solution because this may not work in future if the implementation of UISearchBar changes by the subsequent iOS

问题 I have a UISearchDisplayController that I am currently regretting implementing. The problem is that my search controller accesses a web service and then updates a UITableView by calling [tableView reloadData] . Every time a user enters a key, it searches. I've been able to partially relieve the symptoms by requiring at least three characters before calling the ASIHTTPRequest but there must be a better way. Basically I want the UISearchDisplayController to wait for N seconds OR for the user to

问题 I Have a search bar that searches an array, and updates a UITableView with the results. The table view is a list of books, with titles and authors: Right now, the search bar only searches the titles but I would like to make it search the authors as well. Here is the search code I have (I got it from http://blog.webscale.co.in/?p=228). - (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText { [tableData removeAllObjects];// remove all data that belongs to previous

问题 I am very new to iOS development, very excited though. I have built an app the uses storyboards and populates a UITableView with the contents of a plist file. I managed to get everything running great so far, but now I want to add a search bar much like the one in the contacts app (essentially that's what my app is, just filled with a company directory). I keep reading here and there that there is a very simple way to do this by setting the delegate and data source for the searchbar, but I

问题 I have made a UITableView Controller with a UISearchBar as the Table's header. I have then embedded this View Controller into a UINavigationController, as the root view controller. Now, when I tap on the Search Bar, the SearchBar seems to disappears and displays a white screen. The keyboard appears, but there is no Search Bar. The Table View can scroll, but the search bar has simply vanished. When I implement this UITableViewController without the Navigation Controller, it works perfectly.

问题 In my app i am using UISearchBar in xib with Xcode 6. And i have given bar tin color is clear color. It's working on iOS 7.1 below. But main problem is in iOS 8.0 it's not working clear color. It's displaying black color. See Image : Any one having adventurous of this issue. 回答1: I had the same problem in search bar so i changed the Search style from default to Minimal . And it changed the bar style. 回答2: You can add a 1x1 pixel transparence image as background image to UISearchBar. It would

问题 I am trying to duplicate the UISearchBar animation seen in mobile Safari. Instead of only moving the left margin, the UISearchBar Expands off the screen and then "jumps" into the proper location. The downsizing is similarly uneven. How can I make this animation even like the UISearchBar in mobile safari? searchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0,0,175,44)] autorelease]; searchBar.delegate = self; searchBar.showsCancelButton = YES; searchBar.autoresizingMask =
