在Button Click上移动到iOS中的另一个视图控制器

Question

我是iOS新手,我仍在努力掌握一些事情.我在XCode 5中尝试这个简单的程序,当用户点击按钮时,他将被重定向到另一个视图控制器.我做了其他论坛告诉其他人做的事情,但我似乎遇到了一个错误.

这是我的代码:

在ViewController.m中:

- (IBAction)button1:(id)sender {

    WebServiceViewController *wc = [[WebServiceViewController alloc] 
           initWithNibName:@"WebServiceViewController" 
           bundle:nil];

    [self.navigationController pushViewController:wc animated:YES];
}

我在标题中放置了一个导入"WebServiceViewController.h".

这是错误(不是IDE错误消息,但也不是成功):

这是一个例外:

此外,我正在使用故事板.我有一个用户登录的初始场景.这个场景嵌入了一个导航控制器.登录后,我不会使用segue,因为可以加载几个视图控制器,具体取决于用户登录的类型.我正在尝试执行这个简单的程序,因为我将要使用它将来会更复杂.

我显然错过了一些东西.我希望有一个人可以帮助我.我会非常感激的.

编辑:

这对我有用

WebServiceViewController *wc = [[UIStoryboard storyboardWithName:@"Main" bundle:nil]
  instantiateViewControllerWithIdentifier:@"WebServiceViewController"];
  [self.navigationController pushViewController:wc animated:YES];

storyboardWithName取决于故事板的名称.

Answer 1

试试这个:

WebServiceViewController *wc = [[UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil] instantiateViewControllerWithIdentifier:@"WebServiceViewController"];

还将IdentityboardId设置为Identity Inspector中的WebServiceViewController
