uisearchbar

问题 I'm developing a iPad-only app, and I've got a UITableView inside a UIViewController. I setted a UISearchController as the header of the UITableView. This search control has three scopes. I want the scope selector to be below the search bar . With the following piece of code, I'm able to get it at init, but when I start with the input, the selector goes to the right, and remains there . Here is an animation: And here is the relevant code: self.searchController = [[UISearchController alloc]

问题 I am trying to create an app which has a simple root view controller with a textfield and a button. I want to create a custom table view based on the input of the user in the text field. Imagine this : An App that shows you a list of bikes based on the search input in the text field. Say the user inputs : "Blue Bike" in the text field, the next view will be the one with a table view controller showing all the cells that have Blue or Bike as words in the title.

问题 In interface builder, a UISearchBar seems styled to appear (as you would expect, considering how it is named) in a toolbar, whereas as UITextField is styled to look good on a blank page. Is there a way to make a UISearchBar that does not need to be in a "bar" - such as if you wanted to have multiple search-enabled textfields on a page? My ultimate goal is to have a page full of UITextFields - each of which pops up a predictive search popover as the user fills out the form. I can do the

问题 I'm very new to Xcode so please excuse my ignorance. I have a searchBar and a tableView on a ViewController. I have an IBOutlet for the searchBar and I specified searchBar.delegate = self in viewDidLoad . For some reason textDidChange is not getting called when I type in the search bar. Can anyone help me with this? Thank you. 回答1: I got it working. Even though I specified searchBar.delegate = self in viewDidLoad , it did not work until I specified the searchBar delegate in the storyboard

问题 I'd like to put a search bar in my navigation bar, like safari has. If I add a UISearchBar to my view, it ends up underneath the navigation bar instead. How can I put a search bar in (not under) a unnavigationbar? 回答1: I do it this way: UISearchBar * navSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 232, 44)]; navSearchBar.delegate = self; self.navigationItem.titleView = navSearchBar; [navSearchBar release]; I hope it helps! 回答2: Try putting UISearchBar or UITextField in

问题 I am using UISearchBar to search names in UITableView cells. How to retain the cell state when charachters are entered in UISearchBar? I allocated the checkbox in cellForRowAtIndexPath and suppose I made the selection as shown in the screenshot below. Now if I start searching with letter 'S', checkBox state is 'unchecked' as can be seen below. How do I retain the checkBox state even if the cells are "filtered" while searching. I am aware that cellForRowAtIndexPath is invoked every time when

问题 First of all, quote form iOS User Interface Guidelines When a search bar is present, a scope bar can appear near it. The scope bar displays below the search bar, regardless of orientation, unless you use a search display controller in your code (for more information on the way this works, see UISearchDisplayController Class Reference). When you use a search display controller, the scope bar is displayed within the search bar to the right of the search field when the device is in landscape
