I'm going to become a little crazy for this solution.. I have a TableView with his list of item (an Array from csv Parsing), I need to pass some data from this Array to the list of a Detail TableView when I select a cell..
I reed a bit of solutions and I tried them, but this should be the best solution and the code is conform to the guides.. But when I select a cell I have an "EXC_BAD_ACCESS" but I can't understand where is the zombie object, so I post all class:
#import "inRaggioViewController.h"
#import "iR-DetailViewController.h"
@implementation inRaggioViewController
@synthesize lista, record;
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableArray *listaNonOrdinata = [[NSMutableArray alloc]init];
self.navigationItem.title = @"Tipologia";
NSString *fileString = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Lista1" ofType:@"csv"] encoding:NSUTF8StringEncoding error:nil];
record = [fileString csvRows];
dettaglio = [[NSMutableArray alloc]init];
id doppio = nil;
for (int i=1; i < record.count; i++) {
for (int j=0; j < listaNonOrdinata.count; j++) {
doppio = [[record objectAtIndex:i] firstObjectCommonWithArray:listaNonOrdinata];
if (doppio == nil) {
// [dettaglio addObject:[NSNumber numberWithBool:NO]];
} else {
// [dettaglio addObject:[NSNumber numberWithBool:YES]];
}
}
if (doppio == nil) {
[listaNonOrdinata addObject:[[record objectAtIndex:i]objectAtIndex:0]];
}
}
//Ordino array in ordine alfabetico
lista = [[NSArray alloc]init];
lista = [listaNonOrdinata sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
[listaNonOrdinata release];
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return lista.count;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSString *cellValue = [lista objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
// NSLog(@"dettaglio bool Value: %s",[[dettaglio objectAtIndex:indexPath.row]boolValue] ? @"YES" : @"NO");
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.
NSLog(@"Selezionata riga %i",indexPath.row+1);
iR_DetailViewController *detailViewController = [[iR_DetailViewController alloc]init];
// ...
// Pass the selected object to the new view controller.
detailViewController.navigationItem.title = [self.lista objectAtIndex:indexPath.row];
[detailViewController.lista addObject:[[self.record objectAtIndex:indexPath.row+1]objectAtIndex:1]];
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
}
#pragma mark -
#pragma mark Memory management
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Relinquish ownership any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
// Relinquish ownership of anything that can be recreated in viewDidLoad or on demand.
// For example: self.myOutlet = nil;
}
- (void)dealloc {
[dettaglio release];
[record release];
[lista release];
[super dealloc];
}
@end
The strange thing is that list object work fine in the other methods, only in the selection method it gives problem...
Sorry for my bad english, I don't speak english well. Thanks at all for advice!
I'VE RESOLVED! Thanks to all, the problem was that I must retain list and record objects at the end of viewDidLoad!
