iphone - 在 didSelectRowAtIndexPath 中以编程方式编辑 Controller 的标题

Question

之前，我试图使用以下代码转到另一个 Controller 但失败了

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    RowDetail *rd = [[RowDetail alloc]initWithNibName:@"RowDetail" bundle:nil];
    if ([[allRow objectAtIndex:indexPath.row] is Equal:@"One"]) 
    {
        [rd setTitle:[allRow objectAtIndex:indexPath.row]];
    }
    [self.navigationalController pushViewController:rd animated:NO];
}

我正在使用 Storyboard，所以我发现其他代码对我有用，但我无法为我推送的 Controller 设置标题。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryBoard" bundle:nil];
    RowDetail *rd = [sb instantiateViewControllerWithIdentifier:@"RowDetail"];
    if ([[allRow objectAtIndex:indexPath.row] is Equal:@"One"]) 
    {
        [rd setTitle:[allRow objectAtIndex:indexPath.row]];
    }
    [self.navigationalController pushViewController:rd animated:NO];
}

它工作并显示了 RowDetail Controller ，但我无法编辑标题。知道如何做到这一点吗？

编辑:行详细信息.h

#import <UIKit/UIKit.h>

@interface LecturerDetail : UIViewController

@property (weak, nonatomic) IBOutlet UINavigationBar *rowNavBar;

@property (nonatomic, strong) NSString *lecDetailTitle;
@end

对于 RowDetail，我尝试将 IBOutlet 用于导航栏，但失败了。我仍在尝试让标题显示的方法。

在RowDetailViewController中

@property (nonatomic, strong) NSString *rowDetailTitle;
//synthesize in .m file too

然后

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryBoard" bundle:nil];
    RowDetail *rd = [sb instantiateViewControllerWithIdentifier:@"RowDetail"];
    rd.rowDetailTitle = @"yourTitle";
    [self.navigationalController pushViewController:rd animated:NO];
}

然后在 View 中加载 RowDetailViewController.m

self.navigationItem.title = rowDetailTitle;

希望对您有所帮助，请给予反馈，谢谢。

更新:或者只是简单地这样做:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryBoard" bundle:nil];
    RowDetail *rd = [sb instantiateViewControllerWithIdentifier:@"RowDetail"];
    rd.navigationItem.title = @"yourTitle";
    [self.navigationalController pushViewController:rd animated:NO];
}
