在firstviewcontroller的表视图和tabBarController的secondviewcontroller之间传递数据

Question

我想要将选定的行文本从第一个选项卡的表格视图传递到第二个选项卡的视图标签。我尝试这一点，但它不工作：S stringdir是一个的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]; 
} 

Answer 1

移动detailViewController.stringdir = ...你推视图控制器导航控制器堆栈之前。

- (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]; 
}
