不存储IndexPath.row值

Question

Im trying to store the indexPath.row value but on the next view Im getting 0.

In selectedRecipiesViewController I always get a zero. Here is my code.

MainRecipieViewController.h

@property (assign)   int storageString ;

MainRecipieViewController.m

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (!self.selectedRecipiesViewController) {
        self.selectedRecipiesViewController = [[[SelectedRecipiesViewController alloc] initWithNibName:@"SelectedRecipiesViewController" bundle:nil] autorelease];
    }

    if(indexPath.row == 0) {

        self.selectedRecipiesViewController.passingArray = soupArray; 
    }
    if (indexPath.row == 1) {

        self.selectedRecipiesViewController.passingArray = seaFoodArray;
    }      
    if (indexPath.row ==2) {
        self.selectedRecipiesViewController.passingArray = meatMuttonArray;
    } 

    storageString = indexPath.row;
    NSLog(@"storageString %i",storageString);


    [self.navigationController pushViewController:self.selectedRecipiesViewController animated:YES];
    [tableView reloadData];
}

SelectedRecipiesViewController.m

- (void)viewWillAppear:(BOOL)animated {
     NSLog(@"next view %i" ,self.vc.storageString);
   }

Answer 1

Doesn't appear that you're setting it in the target view controller. Also, it seems that you've created the property storageString in the incorrect header file ( MainRecipieViewController.h ).

SelectedRecipiesViewController.h

@property (assign) int storageString;

Then try using this before you push the view controller:

[self.selectedRecipesViewController setStorageString:indexPath.row];

Finally...

SelectedRecipiesViewController.m

- (void)viewWillAppear:(BOOL)animated {
    NSLog(@"next view %i", self.storageString);
}
