J'aurais pensé que 'self.data=' conserverait les objets NSMutableArray autorelease et les objets NSMutableDictionary qu'ils contiennent, mais j'obtiens finalement EXC_BAD_ACCESS lorsque la méthode cellForRowAtIndexPath de la table tente d'accéder aux NSDictionaries dans self.data.
@property (strong, nonatomic) NSMutableArray *data;
- (void) updateReceivedData:(NSData *) jsonData
{
NSMutableArray *fetchedData = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];
self.data = [self convertDates:fetchedData withFormat:kMySQLDateTimeFormat];
[self.tableView reloadData];
}
}
- (NSMutableArray*) convertDates:(NSMutableArray *) array withFormat:(NSString *) format
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:format];
NSMutableArray *newArray = [NSMutableArray arrayWithArray:array];
for (NSMutableDictionary *dict in newArray)
{
for (id key in dict.allKeys)
{
if ([[dict objectForKey:key] isKindOfClass:[NSString class]])
{
NSString *value = [dict objectForKey:key];
NSDate *date = [dateFormatter dateFromString:value];
if (date) [dict setObject:date forKey:key];
}
}
}
[dateFormatter release];
return newArray;
}
BAD_ACCESS ICI jeté ici entre les NSLogs.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSLog (@"Cell was nil");
cell = [[[CustomCell alloc] init] autorelease];
}
NSDictionary *dict = [[NSDictionary alloc] init];
if (_isFiltered){
dict = [self.filteredData objectAtIndex:indexPath.row];
} else {
dict = [self.data objectAtIndex:indexPath.row];
}
NSLog (@"Filling Label 1");
cell.IDLabel.text = [[dict objectForKey:@"Id"] stringValue];
NSLog (@"Filling Label 2");
cell.firstNameLabel.text = [dict objectForKey:@"firstName"];
[dict release];
return cell;
}
