Xcode6 添加后退按钮

Question

我一直想弄清楚为什么后退按钮不显示。在我的表格视图（动态填充）中我有

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //NSString *continent = [self tableView:tableView titleForHeaderInSection:indexPath.section];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:
                                @"Main" bundle:[NSBundle mainBundle]];
    UIViewController *myController = [storyboard instantiateViewControllerWithIdentifier:@"EditProfileController"];
    [self presentViewController:myController animated:YES completion:nil];

    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

这有效，我可以打开一个名为 EditProfileController 的视图。在我的 EditProfileController.m 我有这个

#import "EditProfileController.h"

@interface EditProfileController ()

@end


@implementation EditProfileController

- (void)viewDidLoad {
    [super viewDidLoad];
    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStylePlain target:self action:@selector(Back)];
    self.navigationItem.leftBarButtonItem = backButton;
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)Back
{
    [self dismissViewControllerAnimated:YES completion:nil]; // ios 6
}

@end

我希望看到后退按钮，但什么也没显示。

这是故事板

Answer 1

您需要将设置视图控制器替换为导航控制器。然后，将设置视图控制器作为导航控制器的根目录。最后，推送编辑视图控制器。

Answer 2

Select settingsViewController 转到 Edit->embed in->navigation controller。并使用协议和委托将数据传递给详细视图
