IOS - how to make default Back button invoke unwind segue -


Is it possible to open the default navigation 'back' button to cgi? I know that it is possible by dragging a standard button on the green out icon, but the default navigation 'back' button is not visible on the storyboard.

It seems that after adding a new contact to the iPhone's Contacts app, it takes you to the screen displaying all information entered, here & # 39; & lt; Back button 'button appears to display a unique segue for the contact list screen. Anyone know how this is done?

I think I can add a standard button and start opening it, but in '& lt;' There is no symbol which I would like to do.

As I know there is no way to set up another task for it, the default back button I spent a lot of time doing this You can create a custom button that looks like the default but the default button can be changed to the next iOS version. To open the operation, you can simply edit a viewControllers array of your navigation controller. For example, in your navigation controller's stack you have 4 view controllers and you want to go back from 4 to 2. Paste it into viewDidLoad: 4 Controller's Method: 

  NSMutableArray * viewControllers = [self.navigationController.viewControllers mutableCopy]; [Remove ViewControllers ObjectEightman: 2]; Self.navigationController.viewControllers = viewControllers;

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
