RISOLTO: Gestire più tableview

[charliec]

Ciao a tutti, all'interno di una view ho tre tableview che dovranno contenere informazioni diverse.

Ho notato impostando le informazioni di header e una valore fittizio sulla prima table queste vengono riportate sulle altre due; evitando la presentazione della prima table le altre due si presentano senza header e senza dati, pur in presenza delle istruzione per inserire dei valori.

Il codice è stato generato da un'applicazione per iPhone che permette il disegno di una applicazione e la generazione del codice.

Di seguito il codice generato in automatico e non modificato da me.

@implementation ScoreView

// Delegates currently only work with one table view, please create a custom
// implementation to handle additional table views
cell.textLabel.text = [tv_ScoresCellTextValues objectAtIndex:indexPath.row];

// Make sure we don't go past end cell detail text values array
if (indexPath.row < [tv_ScoresCellDetailTextValues count]) {
	cell.detailTextLabel.text = [tv_ScoresCellDetailTextValues objectAtIndex:indexPath.row];
}

// Check if this is the selected row
// Note: This goes against Apple UI guidelines, consider removing this or using checkmark accessories
if (indexPath.row == tv_ScoresSelectedRow - 1) {
	[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
}

cell.accessoryType = UITableViewCellAccessoryNone;

return cell;
}

// Handle user selecting row event
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
switch (indexPath.row) {
	default:
		break;
}
}

Penso che il problema sia nella parte del codice che gestisce il numero delle righe e delle informazioni della tabella, la parte dopo il tag #pragma mark TableView Delegates

Un ringraziamento per l'aiuto.

Risolto!!!

All'interno dei metodi presenti #pragma mark TableView Delegates ho aggiunto il controllo su quale tabella si opera, in questo modo è stato possibile gestire le tre view.

Di seguito il codice del primo metodo, gli altri metodi seguono lo stesso principio

- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {

[i]if (table == self.tv_Scores)[/i] {
	return [tv_ScoresCellTextValues count];
}
else {
	[i]if (table == self.tv_ScoresA)[/i] {
		return [tv_ScoresACellTextValues count];
	}
	else {
		return [tv_ScoresBCellTextValues count];
	}
}
}

Le parti in corsivo rappresentano i controlli inseriti. Le tre TableView sono identificate con tv_Scores, tv_ScoresA e tv_ScoresB.

Un saluto a tutti, spero sia utile.
