在firstviewcontroller的表視圖和tabBarController的secondviewcontroller之間傳遞數據

Question

我想要將選定的行文本從第一個選項卡的表格視圖傳遞到第二個選項卡的視圖標籤。我嘗試這一點，但它不工作：S stringdir是一個的NSString

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
SecondViewController *detailViewController = [[SecondViewController alloc]initWithNibName:@"SecondView" bundle:nil]; 
// ... 
// Pass the selected object to the new view controller. 
[self.navigationController pushViewController:detailViewController animated:YES]; 
detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]]; 
NSLog(@"şişşşt %@ ", detailViewController.stringdir); 

[detailViewController release]; 
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
SecondViewController *detailViewController = [[SecondViewController alloc]initWithNibName:@"SecondView" bundle:nil]; 

detailViewController.stringdir= [ws2.CustomerName objectAtIndex:[indexPath row]]; 
NSLog(@"şişşşt %@ ", detailViewController.stringdir); 

// Pass the selected object to the new view controller. 
[self.navigationController pushViewController:detailViewController animated:YES]; 

[detailViewController release]; 
}
