Unity IOS - Open a In-App Web Browser

Your Unity app will have to talk to your main app delegate (UnityAppController.mm) and then you just use Objective C to create an add a UIWebView in your main window to open up the URL.

For the interface from Unity to iOS you will need to define the following in your .cs:

 [DllImport ("__Internal")]
 private static extern void _Hello (string service);
 
 public static void Hello(string message)
     {
         // Call plugin only when running on real device
         if (Application.platform != RuntimePlatform.OSXEditor)
             _Hello(message);
     }
 
 

Then in your objective C Xcode:

     extern "C" {
         
         void _Hello (const char* message)
         {
             NSLog(@"Hello");
 
 NSString *msg = [NSString stringWithFormat: @"%s", message];
             [GetAppController() hello:msg];
         }
 
     }

In your Objective C main app delegate class proper you can then have:

 -(void)hello:(NSString*)message {
      NSLog(@"hello: %@",message);
 // or just open a new UIWebView here and attach it to the window
 }
