Guys, i have a little issue here. Im doing a search to my UITableView. I search “iPhone”, it returns to me one result. Its ok. iPhone just has one result. But when i search for iPad, that has two results, it gives me 2 results, but the first row stills displaying iphone info. The second display the iPad correct information.
When i click on search bar again to search another word, it gives me the two desired rows of ipad. But when i press the cancel button, it returns to the iPhone and iPad rows.
What im doing wrong?
Thanks
Cell and Table Methods:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.listCod count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = @"SearchResult";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell =
[[[UITableViewCell alloc]
initWithFrame:CGRectMake(0, 0, 180, 200)
reuseIdentifier:MyIdentifier]
autorelease];
UIColor *bkgColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"SearchViewTableCellBackground.png"]];
UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ];
backgroundView.backgroundColor = bkgColor;
cell.backgroundView = backgroundView;
// Foto do produto
UIView *teste = [[UIView alloc] init];
teste.frame = CGRectMake(5, 5, 100, 100);
teste.backgroundColor = [UIColor blueColor];
[cell addSubview:teste];
// Label de Marca
UILabel *marca = [[UILabel alloc] init];
marca.frame = CGRectMake(115, 10, 195, 25);
marca.backgroundColor = [UIColor clearColor];
marca.textColor = [UIColor grayColor];
NSString *marcaString = [self.listMarca objectAtIndex:indexPath.row];

// Label do nome do produto

//Preco

// Manda preco e parcela pra tratar

And the search bar methods:
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
[searchBar setShowsCancelButton:YES animated:YES];
self.theTableView.allowsSelection = NO;
self.theTableView.scrollEnabled = NO;
[theTableView setRowHeight:110];
}
- (void)searchDisplayController:(UISearchDisplayController *)controller
willShowSearchResultsTableView:(UITableView *)tableView
{
[tableView setRowHeight:[[self theTableView] rowHeight]];
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
[self.tableData removeAllObjects];
[self.theTableView reloadData];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
searchBar.text=@"";
[searchBar setShowsCancelButton:NO animated:YES];
[searchBar resignFirstResponder];
self.theTableView.allowsSelection = YES;
self.theTableView.scrollEnabled = YES;
}
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
return NO;
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
// Converte a String do campo de busca
NSString* buscaGet =
[searchBar.text stringByAddingPercentEscapesUsingEncoding:
NSASCIIStringEncoding];
// Conecta com a URL
NSString *endereco = [[NSString alloc] initWithFormat:@"http://localhost/icomm/test.php?nome=%@", buscaGet];
// Lê o resultado
TBXML * tbxml = [[TBXML tbxmlWithURL:[NSURL URLWithString:endereco]] retain];
TBXMLElement * rootXMLElement = tbxml.rootXMLElement;
TBXMLElement * item = [TBXML childElementNamed:@"produto" parentElement:rootXMLElement];
listCod = [[NSMutableArray alloc] init];
listMarca = [[NSMutableArray alloc] init];
listName = [[NSMutableArray alloc] init];
listPreco = [[NSMutableArray alloc] init];
listParcela = [[NSMutableArray alloc] init];
while (item) {
// Seta a id do produto
TBXMLElement * codigo = [TBXML childElementNamed:@"item" parentElement:item];
NSString * codProd = [TBXML textForElement:codigo];
[self.listCod addObject:codProd];
// Seta a marca do produto
TBXMLElement * marca = [TBXML childElementNamed:@"marca" parentElement:item];

// Seta o nome do produto

];
}
NSLog(@"%@", self.listName);
[searchBar setShowsCancelButton:NO animated:YES];
[searchBar resignFirstResponder];
self.theTableView.allowsSelection = YES;
self.theTableView.scrollEnabled = YES;
//Remove tudo da table e recarrega
[[[self searchDisplayController] searchResultsTableView] performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];
[tableData removeAllObjects];
[theTableView reloadData];
}
Thanks for all.
You are only setting your labels up inside the
if (cell == nil)part of your code. This only gets called the first time a cell is created; after that the cell is dequeued for reuse and you don’t create a new cell. If you want to dequeue your cells like that, you need to set the text (and any other property of the label that might change) outside of that if statement. In order to get references to your labels, you will need to use tags andviewWithTag:.Or if you want to simplify things, don’t dequeue your tableCells; though this could lead to performance issues if you have a lot of cells.
