我有2页.第一个是tableView,第二个是当我点击任何单元格时进入下一页(视图)的模式segue.我想在导航栏的下一页中添加后退按钮.这是我在视图页面中的代码: ViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.lable.text = obji.Name;
    self.lable2.text = obji.Descript;

    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(Back)];
    self.navigationItem.leftBarButtonItem = backButton;
}

- (IBAction)Back
{
    //I dont know that how return pervious page
}
