sectionsTitle
「Category1」または「Category2」と書くと、セクションCategory1またはCategory2が見つかりますが、ここから、このすべてのセクションでNAMESで検索する必要があります。
NSDictionary *dict = [[tableData objectForKey:[sectionsTitle objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];
[NSString stringWithFormat:@"%@", [dict objectForKey:@"Name"]];
名前で検索するには、コードで何を変更する必要がありますか? 今、私はNSArray、NSMutableArray、およびNSDictionaryのすべてと混同しています:(
次のようにデータをロードします。
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *path = [[documentPaths lastObject] stringByAppendingPathComponent:@"data.plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];
NSMutableDictionary *resultDic = [[NSMutableDictionary alloc] init];
NSMutableArray *resultArray = [[NSMutableArray alloc] init];
sectionKeys = [NSMutableArray new];
sectionsTitle = [NSMutableArray new];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"blueKey"])
{
ann = [dict objectForKey:@"Category1"];
[resultArray addObject:@"Category1"];
[resultDic setValue:ann forKey:@"Category1"];
[sectionKeys addObject:@"Section 1"];
}
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"yellowKey"])
{
ann = [dict objectForKey:@"Category2"];
[resultArray addObject:@"Category2"];
[resultDic setValue:ann forKey:@"Category2"];
[sectionKeys addObject:@"Section 2"];
}
self.tableData = resultDic;
self.sectionsTitle = resultArray;
[myTable reloadData];
これは私がデータをフィルタリングする方法です:
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:@"SELF contains[cd] %@",
searchText];
searchResults = [sectionsTitle filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
これは私のテーブルがどのように見えるかです:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
if (tableView == self.searchDisplayController.searchResultsTableView) {
return 1;
}else{
return sectionKeys.count;
}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if (tableView == self.searchDisplayController.searchResultsTableView) {
return @"Search";
}else{
return [sectionKeys objectAtIndex:section];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
} else {
int num = [[tableData objectForKey:[sectionsTitle objectAtIndex:section]] count];
return num;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
} else {
NSDictionary *dict = [[tableData objectForKey:[sectionsTitle objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];
cell.textLabel.font = [UIFont fontWithName:@"Avenir" size: 16.0];
cell.detailTextLabel.font = [UIFont fontWithName:@"Avenir" size: 12.0];
cell.textLabel.text = [NSString stringWithFormat:@"%@", [dict objectForKey:@"Name"]];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@", [dict objectForKey:@"Address"]];
}
return cell;
}
