uisearchbar

问题 Most of the example I found is in Objective - C which is very hard for me to understand can someone provide an example regarding this question in Swift . Here is one solution but it is in Objective C . 回答1: func searchBar(searchBar: UISearchBar, textDidChange searchText: String) { print("after every text gets changed") timer.invalidate() timer = NSTimer.scheduledTimerWithTimeInterval(5, target: self, selector: #selector(ViewController.output), userInfo: searchText, repeats: false) } func

问题 I have an instance of a UISearchBar added to the title view of a UINavigationBar. When there is text already set and the search bar starts editing it resizes its contents to allow space for the Cancel button, although, the resulting animation stretches the text, as showed in the gif below Is there anything that can be done to avoid this defect effect?

问题 As shown below, my UISearchBar is getting resized when I tap on the search field. It animates nicely to cover the navigation bar, and then pop... it shrinks. The setup The UISearchBar is inside a vanilla UIView set as the tableHeaderView . I'm using a UIView (as opposed to setting the UISearchBar as the header) because I would like to put additional views in the header. The view is defined in a XIB file and the UISearchBar is anchored to all of its borders. The constraints don't seem to

问题 We have a UITableView with a searchbar added with the searchDisplayController . We want to have translucency off throughout the app. I have the translucency off for the navigation bar and other bars, but not the search bar when it uses the display controller. In one part of the app when we use the search bar but not the display controller, the translucency is set correctly. How can I set the translucent property of the UISearchBar with the display controller to be NO? EDIT: this is my code in

问题 I read all questions on stackoverflow but none of them could solve my problem. I created a UICollectionView and and anchored a searchBar inside of the navigationBar without using Storyboards! class UserSearchController: UICollectionViewController ,.. {.. lazy var searchBar: UISearchBar = { let sb = UISearchBar() sb.placeholder = "Enter username" sb.barTintColor = UIColor.gray UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).backgroundColor = UIColor.rgb(red: 230, green:

问题 What I am trying to do : I want to move the x and y coordinates of my search bar on a touch event. I have placed my code in viewDidLoad to test it out. However I am getting an error. Error: Property 'frame' not found on object of type 'UISearchBar'.

问题 I have a searchBar showing as part of the tableViewHeader as created in the storyboard. However I would like to hide it under some circumstances. To accomplish this, I set the tableHeaderView.frame to a height of 0. To show it again, I set the tableHeaderView.frame to its original height.

I tried [self.searchBar sizeToFit] after it is shown without any success. I

问题 I have an issue. I am using the parse framework and I need to add a search bar for my PFQueryTableViewController. I need to rewrite the below methods "number of sections", "number of rows in section" as well as "cell for row at index path". After rewriting the above methods I'm finding that even through I enabled the pagination function, the "load more" label doesn't appear. Only the first 10(I set 10 per page) records are displayed.
