将搜索添加到 tvOS UITableView
Add Search to tvOS UITableView
我的 tvOS 应用程序上有一个包含 400 多个对象的 TableView，它确实需要具有搜索功能。
在阅读了 Apple 的一些示例代码后，这就是我所拥有的。 SecondViewController 是主要 TableView 所在的位置，而我只是将 resultsViewController 的名称保留为与 Apple 相同的名称。在主要的我有：
-(void)viewDidLoad {
[super viewDidLoad];
_resultsTableController = [[APLResultsTableController alloc] init];
_searchController = [[UISearchController alloc] initWithSearchResultsController:self.resultsTableController];
self.searchController.searchResultsUpdater = self;
[self.searchController.searchBar sizeToFit];
self.tableView.tableHeaderView = self.searchController.searchBar;
// we want to be the delegate for our filtered table so didSelectRowAtIndexPath is called for both tables
self.resultsTableController.tableView.delegate = self;
self.searchController.delegate = self;
self.searchController.searchBar.delegate = self; // so we can monitor text changes + others
// Search is now just presenting a view controller. As such, normal view controller
// presentation semantics apply. Namely that presentation will walk up the view controller
// hierarchy until it finds the root view controller or one that defines a presentation context.
//
self.definesPresentationContext = YES; // know where you want UISearchController to be displayed
}
- (void)viewWillAppear:(BOOL)animated {
if (self.searchControllerWasActive) {
self.searchController.active = self.searchControllerWasActive;
_searchControllerWasActive = NO;
if (self.searchControllerSearchFieldWasFirstResponder) {
[self.searchController.searchBar becomeFirstResponder];
_searchControllerSearchFieldWasFirstResponder = NO;
}
}
NSBundle *bundle = [NSBundle mainBundle];
self.files = [bundle pathsForResourcesOfType:@"pdf" inDirectory:@"AIMPDF"];
NSString *documentsDirectoryPath = [self.files objectAtIndex:thepath.row];
self.title = @"Devo Songs";
self.filenames = [[documentsDirectoryPath lastPathComponent] stringByDeletingPathExtension];
NSLog(@"%@", filenames);
if ([self savedSearchTerm])
{
//[[[self searchDisplayController] searchBar] setText:[self savedSearchTerm]];
}
NSMutableArray *names = [NSMutableArray arrayWithCapacity:[self.files count]];
for (NSString *path in self.files) {
[names addObject:[[path lastPathComponent] stringByDeletingPathExtension]];
}
self.files = names;
self.tableView.backgroundColor = [UIColor whiteColor];
self.parentViewController.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"iphonebackground.png"]];
[super viewDidLoad];
UIBarButtonItem *plan = [[UIBarButtonItem alloc] initWithTitle:@"Plan Devo" style:UIBarButtonItemStylePlain target:self action:@selector(picking)];
self.navigationItem.rightBarButtonItem = plan;
[super viewWillAppear:animated];
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[searchBar resignFirstResponder];
}
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController {
// update the filtered array based on the search text
NSString *searchText = searchController.searchBar.text;
NSMutableArray *searchResults = [self.files mutableCopy];
// strip out all the leading and trailing spaces
NSString *strippedString = [searchText stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
// break up the search terms (separated by spaces)
NSArray *searchItems = nil;
if (strippedString.length > 0) {
searchItems = [strippedString componentsSeparatedByString:@" "];
}
// build all the "AND" expressions for each value in the searchString
//
// hand over the filtered results to our search results table
APLResultsTableController *tableController = (APLResultsTableController *)self.searchController.searchResultsController;
tableController.filteredProducts = searchResults;
[tableController.tableView reloadData];
}
- (void)handleSearchForTerm:(NSString *)searchTerm
{
[self setSavedSearchTerm:searchTerm];
if ([self searchResults] == nil)
{
NSMutableArray *array = [[NSMutableArray alloc] init];
[self setSearchResults:array];
array = nil;
}
[[self searchResults] removeAllObjects];
if ([[self savedSearchTerm] length] != 0)
{
for (NSString *currentString in [self files])
{
if ([currentString rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location != NSNotFound)
{
[[self searchResults] addObject:currentString];
}
}
}
}
在结果视图控制器中，我有：
@implementation APLResultsTableController
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.filteredProducts.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *filename = [[[self.filteredProducts objectAtIndex:indexPath.row] lastPathComponent] stringByDeletingPathExtension];
NSInteger row = [indexPath row];
NSString *contentForThisRow = nil;
contentForThisRow = filename;
static NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
[[cell textLabel] setText:contentForThisRow];
cell.textLabel.font = [UIFont fontWithName:@"Helvetica Neue" size:90];
cell.textLabel.textColor = [UIColor blackColor];
cell.backgroundColor = [UIColor lightGrayColor];
return cell;
}
@end
我在主 TableView 的顶部添加了搜索栏，但是当我开始输入字母时没有任何变化。
Apple 在 iOS 8 中弃用了 UISearchDisplayController，并在 iOS 9 中将其删除，这就是它在 tvOS 上不可用的原因。
您需要使用 UISearchController, which you initialize and present in code. Apple provides an example of how to do this in SearchViewController.swift, in the UIKitCatalog tvOS 示例代码。
好的，所以在我的头撞到砖墙上的 all-day 事件之后，我终于把它设置好了。请注意，我讨厌 Apple 的教程和示例代码如何让它变得过于复杂。他们添加了一个 APLProducts 的 NSObject，一个 BaseTableView，并在他们的教程中创建了几个复合的 NSPredicates，以便在 TableView 中使用搜索。本来可以简单得多。
最后只需要3个类:
原始表格视图
结果表视图

在 OTV 中，我为 SearchController 和一个名为 searchResults 的 NSMutableArray 声明了 属性。我所有的 PDF 文件都在目录 AIMPDF 中。我根据这些文件制作数组，删除显示扩展名。正是在代码的“搜索更新”部分，Apple 对他们试图做的所有事情都失去了控制。看在上帝的份上，让教程变得简单。
