问题 I have implemented a UITableView with search bar (and search display) - all works fine, but the table results do not get updated until the search bar cancel button is tapped. Delegate methods: - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { // asynchronous request with [self.tableView reloadData] in the connectionDidFinishLoading [self getProductData:searchBar.text]; [searchBar resignFirstResponder]; [self.tableView reloadData]; } - (void)searchBar:(UISearchBar *)searchBar

问题 I have a question for several days about UISearchBar. I don’t understand how the search bar of Instagram Explorer page works, for example : http://imgur.com/40I38mn I mean, at the beginning the ViewController shows the searchBar, and below a view(tableview?) which has nothing to do with it. And when the user begins a search by touching the search bar, the right tableview with data appears. In reality, are there multiple TableView ? UISearchBar calls an another view ? And… simple UISearchBar

问题 I have an UITabBar controller managing several controllers (using SDK 3.0). One of these is a tableView controller and I need to provide a search capability using the UISearchDisplayController. All of my code is based on Apple TableSearch example. However, when clicking on the tab, the tableView controller appears showing its related content, but no searchBar appears. I have checked the xib in IB to make sure that all of the outlets are properly set, but no matter what I try self

问题 On iOS 7 UISearchBar the placeholder text is centred and I want to disable that and make it always stick to the left like it was before. There is a private method setCenterPlaceholder, on the diffs and calling this with a BOOL will make the trip. https://gist.github.com/nscoding/7220368 Header file @interface NSCodingSearchBar : UISearchBar // Default by the system is YES. // https://github.com/nst/iOS-Runtime-Headers/blob/master/Frameworks/UIKit.framework/UISearchBar.h @property (nonatomic,

问题 Somehow i dun know why does the default animation fails. my Search bar did not shift up as it supposed to be. the view is in UIView, i'm wondering if this is the problem. Included the IB layout 回答1: The searchbar doesn't actually move in the 'push-up' animation. Rather it stays in place while the navbar goes up, thus pulling the rest of the view with it. You should be able to move the search bar manually in code by registering as its delegate (UISearchBarDelegate) and responding to these

问题 I don't know how to modify the original searchIcon 's color. 回答1: You can use a custom image of a white search icon, as the search bar will not modify your supplied image. To set a custom image, use this method. (Link to documentation.) - (void)setImage:(UIImage *)iconImage forSearchBarIcon:(UISearchBarIcon)icon state:(UIControlState)state; Example Code: [searchBar setImage:[UIImage imageNamed:@"SearchIcon"] forSearchBarIcon:UISearchBarIconSearch state:UIControlStateNormal]; In Swift:

问题 I want to show no scope bar when the table is empty (before the search bar edits for the first time), no scope bar when it's editing, and finally show it when editing done. I know about the UISearchBarDelegate protocol, but I don't know how to show/hide the scope bar with animation. I know UISearchBar has setShowsScopeBar: , but no setShowsScopeBar:animated: the way it does for setShowsCancelButton:animated . Edit It's important that to call [searchBar sizeToFit] after showing/hiding the

问题 I am trying to create a table view in which it has list of dishes with sections and when we select a row it should go to new table view which consist list of popular restaurants which serves that specific food. I have created the table view with sections, but my app crashes when I reach at end of the list view. I have added my code below with the snapshot of table view and error. @IBOutlet weak var dishtable: UITableView! @IBOutlet weak var namlbl: UILabel! var Dishes = ["POPULAR Dishes": [

问题 I've added a UISearchBar to a UICollectionView and in the delegate searchBar:textDidChange: filter my model and call [collectionView reloadData] . reloadData (as well as reloadSection, etc) wants to take away firstResponder from the searchbar's textfield, thus dismissing the keyboard. I am trying to build a "live updating" filter and so it's annoying to have the keyboard go away after each character typed. Any ideas? 回答1: In searchBar delegate function , I use performBatchUpdates, first

问题 When I apply UISearchBarStyleMinimal my scope buttons get drawn over the search bar. Here is how it looks like on regular style: And when I apply the style, I get something like this: Does anyone have an idea why this happens, and what can I do to fix it. When I remove the scope buttons it look really nice, but I need the scope button for my app. 来源： https://stackoverflow.com/questions/24571683/uisearchbarstyleminimal-shows-scope-buttons-on-top-of-uisearchbar
