有没有人知道如何有条件地"停止"segue过渡:

我的表格视图单元格表示可以在深入"详细"视图中查看的产品......或者不能!(这取决于几件事)

现在我的应用程序认为所有产品都"解锁":

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow];
    ListaProdottiController *prodottiViewController = [segue destinationViewController];
    prodottiViewController.blocco = [self.fetchedResultsController objectAtIndexPath:selectedRowIndex];
}

此时如何取消行选择=>向下钻取？

我有3个segues到3个不同的视图.2实现没有问题,是在创建第三个问题时.

我有以下didSelectRowAtIndexPath方法:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    NSLog(@" ----------  did select row");

    if(indexPath.section == 0){
        if(indexPath.row == [self.data count]-1){
            //prior to adding this, everything works
            [self performSegueWithIdentifier:@"MoreComments" sender:self];
        }else{
            [self performSegueWithIdentifier:@"FriendView" sender:friend];
        }
    }else if(indexPath.section == 1){
        if(indexPath.row == [self.data2 count]-1){
            [self performSegueWithIdentifier:@"MorePosts" sender:self];
        }else{
            [self performSegueWithIdentifier:@"FriendView" sender:friend];
        }
    }
}

我有以下prepareForSeque方法:

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if([segue.identifier isEqualToString:@"MorePosts"]){
        MorePostsViewController *mfamvc = segue.destinationViewController;
        mfamvc.data = self.data;
    }else if([segue.identifier isEqualToString:@"FriendView"]){
        FriendViewController *fvc = segue.destinationViewController;
        fvc.friend = friend;
    }else if([segue.identifier isEqualToString:@"MoreComments"]){
          MoreCommentsViewController *mcvc …
