推送DetailViewController和UITableView的问题

Question

更新

DetailViewController *wordDetail = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
wordDetail.wordWordString = [[NSString alloc] initWithString:[[myArray objectAtIndex:indexPath.row] objectForKey:@"word"]];
wordDetail.wordDefinitionString = [[NSString alloc] initWithString:[[myArray objectAtIndex:indexPath.row] objectForKey:@"definition"]];
wordDetail.title = [[myArray objectAtIndex:indexPath.row] objectForKey:@"name"];

[self performSegueWithIdentifier:@"showDetail" sender:self];

这是我对segue的新准备（你的意思是我不再需要它，如果我使用上述方法，或者根本不是吗？我实际上现在确定我的所有标识符是否正在排队......你是什么？想？

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
if ([[showDetail] isEqualToString:@"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSDate *object = _objects[indexPath.row];
[[segue destinationViewController] setDetailItem:object];

图可能也有助于查看我的DetailViewController.m ......

-(void)setDetailItem:(id)newDetailItem
{
if (_detailItem != newDetailItem) {
    _detailItem = newDetailItem;

    // Update the view.
    [self configureView];
}

if (self.masterPopoverController != nil) {
    [self.masterPopoverController dismissPopoverAnimated:YES];
}        
}

-(void)configureView
{
//Update the user interface for the detail item.

if (self.detailItem) {
    self.detailDescriptionLabel.text = [self.detailItem description];
}
}


- (void)viewDidLoad
{
    wordWordLabel.text = wordWordString;
    wordDefinitionLabel.text = wordDefinitionString;

    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self configureView];
}

您的第一部分代码很好。然而，它正在创建一个DetailViewController然后推动它。这意味着从来没有一个Segue，所以你的第二个代码根本不重要。您需要决定使用哪个。

[self.navigationController pushViewController:wordDetail animated:YES];

该行在堆栈上推送viewController。 OR

[self performSegueWithIdentifier:@"showDetail sender:self];

将在名为showDetail的故事板中使用segue。你不能同时拥有这两者，你需要选择。
