2.UISearchBar得到焦点并开始编辑时,执行该方法

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar{ [search setShowsCancelButton:YES animated:YES]; [self.navigationController setNavigationBarHidden:NO animated:YES]; //显示遮盖层 [self controlAccessoryView:0.55]; rerutn YES;}

3.取消按钮被按下时执行的方法

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{[search resignFirstResponder];[search setShowCancelButton:NO animated:YES];搜索相关数据[collectionView searchDataBySearchString:search.text];[self.navigationController setNavigationBarHidden:NO animated:YES];//隐藏遮盖层[self controlAccessoryView:0];}

4.当搜索内容变化时,执行此方法(实现时时搜索)

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{搜索相关数据[collectionView searchDataBySearchString:search.text];[self.navigationController setNavigationBarHidden:NO animated:YES];//隐藏遮盖层[self controlAccessoryView:0];}

5.键盘中,搜索按钮被按下执行的方法

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{[search resignFirstResponder];[search setShowCancelButton:NO animated:YES];搜索相关数据[collectionView searchDataBySearchString:search.text];[self.navigationController setNavigationBarHidden:NO animated:YES];//隐藏遮盖层[self controlAccessoryView:0];}
