Question

我是Swift Development的初学者，我一度陷入困境。我有一个ViewController1（入口点），导航控制器和ViewController2。 ViewController2包含 XLPagerTabStrip ，并嵌入在Navigation Controller中。我可以使用下面的代码从ViewController1移动到Navigation控制器。

boolean clicked = false;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup  container,Bundle savedInstanceState) {
View view =  inflater.inflate(R.layout.camera_connection_fragment, container, false);
Button button = (Button) view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
    //Put your logic in the if(clicked) control.
    clicked = true // you can delete this line
    (your logic)
  }
});

return view;

}

@Override
   protected void onStart() {
    super.onStart();
    //You can delete the below if check and move your logic to onClick method
    if(clicked) {
     (your logic)
    }
}

现在问题是我无法从导航控制器移回ViewController1。

能够从 ViewController1 - ＆gt;移动NavigationController - ＆gt; ViewController2

但无法撤回，即 ViewController1＆lt; - NavigationController＆lt; - ViewController2

先谢谢。

Answer 1

尝试任何一个

window.$ = window.jQuery = require('jquery');

Answer 2

在您的代码中删除此行：

self.present(navigationController, animated: true, completion: nil)

当你想要回去时，只需致电：

navigationController?.popViewController(animated: true)

Answer 3

看起来你在一行中遗漏了自己，所以如果你把它更新为这样：

self.navigationController.pushViewController(viewController, animated: true)

现在应该可以工作......

从导航控制器返回View Controller？
