I have a UISearchBar. I want the the keyboard to go away as soon as user hits search...i did try resignFirstResponder but that didn't work. any help would be appreciated

- (void)viewDidLoad {
    [super viewDidLoad];

    self.title = NSLocalizedString(@"Songs", @"Search for songs");


    NSMutableArray *array = [[NSArray alloc]initWithObjects: @"Book_1", @"Book 2", @"Book _ 4", nil];
    self.booksArray = array;
    [array release];
    search.delegate=self;
    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

谢谢TC

推荐答案

请确保注意以下事项.(希望您在谈论键盘的搜索按钮.)

Please make sure of following things.(I hope you are talking about search Button of keyboard.)

1. 您已将searchBar的IBOutlet与它的变量search连接起来.
2. 您不会在代码的任何地方取消引用搜索变量(重新分配它).
3. 您的- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar方法与searchBar所在的viewcontroller位于相同的位置.
4. 请NSLog(@搜索栏实例:％@"，搜索);在viewDidLoad方法和searchBarSearchButtonClicked中，并验证两个实例是否相同(如果不相同)，则您正在search中重新分配代码中的某个位置.
5. 在[searchBar resignFirstResponder]; NSLog之后(@"isFirstResponder:％d"，[searchbar isFirstResponder])；和NSLog(@"Next Responder : %@",[searchBar nextResponder]);
6. 是- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar点击键盘的搜索按钮时调用方法?确保在searchBar后面无意添加了键盘responder(例如textField，textView或其他searchBar).请同时通过xib进行检查.

1. You have connected your IBOutlet of searchBar with its variable search.
2. You are not de-referring search variable anywhere in your code(reassigning it).
3. Your - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar method is in same viewcontroller as searchBar is in.
4. Please NSLog(@"Search Bar Instace : %@",search); in viewDidLoad method and searchBarSearchButtonClicked and verify that both instances are same if not then you are search is getting reassigned somewhere in code.
5. Just after [searchBar resignFirstResponder]; NSLog(@"isFirstResponder : %d",[searchbar isFirstResponder]); and NSLog(@"Next Responder : %@",[searchBar nextResponder]);
6. Is - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBarmethod is being called when you tap search Button of keyboard? Make sure there are no keyboard responder(like textField,textView or other searchBar) is added behind your searchBar may be unintentionally. Please check it through xib also.

谢谢
