无法从xib调用故事板

Question

我是iOS开发的新手。我正在尝试从xib文件连接到storyboard。我的xib视图控制器有一个“登录”，成功后应该连接到storyboard。我已经在Google和StackOverflow上搜索了解决方案，我正在使用到处都提供的这段代码：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    YourViewController * yourView = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"identifier ID"];

我已经为我的Storyboard创建了一个标识符。不过，无论我尝试什么方法都无法重定向到Storyboard。当登录完成后，我回到我的主视图控制器（xib），而应该重定向到Storyboard。下面是我在名为ProfileTabView.m的文件中的代码：

-(void) loginViewDidFinish:(NSNotification*)notification
{
    [[NSNotificationCenter defaultCenter] removeObserver:self];

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    ProfileTabView * yourView = (ProfileTabView *)[storyboard instantiateViewControllerWithIdentifier:@"myID"];

}

我已经在登录成功后被调用的函数中实现了这段代码。然而，“Storyboard”故事板从未被调用过。我是否做得对？我应该在其他地方写这段代码吗？

非常感谢任何帮助 :)

你需要通过push/present/addSubview的方式将"yourView".view添加到视图层次结构中。这段代码在loginViewDidFinish中的哪个部分？ - San

还有一步：呈现新的视图控制器...

-(void) loginViewDidFinish:(NSNotification*)notification
{
    [[NSNotificationCenter defaultCenter] removeObserver:self];

    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    ProfileTabView * yourView = (ProfileTabView *)[storyboard instantiateViewControllerWithIdentifier:@"myID"];

    // it might be better to rename 'ProfileTabView' as 'ProfileTabViewController'
    // and 'yourView' as 'profileTabVC', by convention.  Anyway ...

    [self.presentViewController:yourView animated:YES completion:^{}];
}

如果您的登录VC在导航控制器中，那么您将推送新的视图控制器：

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

Answer 2

-(void) loginViewDidFinish:(NSNotification*)notification
{
NSNotificationCenter.defaultCenter().removeObserver(self)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier("ViewControllerID") as UIViewController
    self.presentViewController(vc, animated: true, completion: nil)
}
