搜索键在ios中按下时没有任何反应

本文介绍了搜索键在ios中按下时没有任何反应的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我是iOS开发的新手。我想在我的应用中添加一个搜索栏。当触摸搜索栏时，键盘会弹出。但是当我按下搜索按钮时，它不会关闭键盘。我的控制器.h文件如下。 @ interface SearchViewController： UIViewController< ; UITableViewDelegate，UITableViewDataSource，UISearchBarDelegate> { IBOutlet UISearchBar * searchBar; IBOutlet UITableView * tableView; NSMutableArray * listOfItems; NSMutableArray * copyListOfItems; NSArray *歌曲; BOOL搜索; BOOL letUserSelectRow; } @property（强大的，非原子的）NSArray *歌曲; @property（强，非原子）UITableView * tableView; @property（强，非原子）UISearchBar * searchBar; @end 我在.m文件中实现了以下方法。但他们没有调用。 - （ void ）searchBarSearchButtonClicked ：（UISearchBar *）searchBar { NSLog（ @ 搜索点击）; [self.searchBar resignFirstResponder]; } - （ void ）searchBarCancelButtonClicked：（UISearchBar *）searchBar { NSLog（ @ 取消点击）; } 有人能解释一下原因吗？解决方案 我没有看到任何引用链接到搜索按钮的UIButton类或IBOutlet或者捕获按钮点击事件的IBAction方法。 我想你会发现以下链接很有用： http://klanguedoc.hubpages.com/hub/IOS-5-Tutorial-on-How-To-Dismiss-the-UI-Keyboard [ ^ ] 如果您在阅读上述链接中的文章后仍然遇到问题，只需在.h文件中添加一个喊叫：） 添加委托并初始化声明 @ interface RestaurantViewController：UIViewController< ui searchdisplaydelegate，> UISearchDisplayController * resName_search; UISearchBar * mySearchBar; .m文件中的 mySearchBar = [[UISearchBar alloc] init]; [mySearchBar setDelegate： self ]; // [mySearchBar setShowsCancelButton：YES animated：NO]; resName_search = [[UISearchDisplayController alloc] initWithSearchBar：mySearchBar contentsController： self ]; resName_search.delegate = self ; resName_search.searchResultsDataSource = self ; resName_search.searchResultsDelegate = self ; [ self .view addSubview：resName_search.searchBar]; [resName_search.searchBar setFrame：CGRectMake（ 0 。 0 ，barOriginY + 79。 0 ， 106 。 0 ， 40 。 0 ）]; - （ BOOL ）searchBarShouldBeginEditing：（UISearchBar *）searchBar { NSLog（ @ 输入文字点击）; 返回 是; } - （ BOOL ）searchBarShouldEndEditing：（UISearchBar *）searchBar { NSLog（ @ 取消点击）; 返回 是; } I'm really new to iOS development. I wanted to add a search bar to my app. When touching on the search bar key board pops up. But when I press the search button it doesn't dismiss the keyboard. My controller .h file is as belows.@interface SearchViewController :UIViewController<UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate>{ IBOutlet UISearchBar *searchBar; IBOutlet UITableView *tableView; NSMutableArray *listOfItems; NSMutableArray *copyListOfItems; NSArray *songs; BOOL searching; BOOL letUserSelectRow;}@property(strong,nonatomic)NSArray *songs;@property(strong,nonatomic)UITableView *tableView;@property(strong,nonatomic)UISearchBar *searchBar;@endI have implemented the following methods in .m file. But they don't invoke.-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{ NSLog(@"search clicked"); [self.searchBar resignFirstResponder];}-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{ NSLog(@"Cancel Clicked");}Can anybody explain me the reason? 解决方案 Hi,I don't see any reference to a UIButton class or IBOutlet linked to the search button or an IBAction method that will capture the button click event.I think you will find the following link useful:http://klanguedoc.hubpages.com/hub/IOS-5-Tutorial-on-How-To-Dismiss-the-UI-Keyboard[^]If you still have problems after going through the article in above link, just put a shout :)in .h file add delegate and initialize declare@interface RestaurantViewController : UIViewController <uisearchdisplaydelegate,> UISearchDisplayController *resName_search; UISearchBar *mySearchBar;in .m file mySearchBar = [[UISearchBar alloc]init]; [mySearchBar setDelegate:self];// [mySearchBar setShowsCancelButton:YES animated:NO]; resName_search = [[UISearchDisplayController alloc] initWithSearchBar:mySearchBar contentsController:self]; resName_search.delegate = self; resName_search.searchResultsDataSource = self; resName_search.searchResultsDelegate = self; [self.view addSubview:resName_search.searchBar]; [resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar{NSLog(@" enter text clicked"); return YES;}-(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar{ NSLog(@"cancel clicked"); return YES;} 这篇关于搜索键在ios中按下时没有任何反应的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
