title: OpenUrl and itms-services with credentials
body: <p>I want to install an app from inside another app. I know it is possible with the following code:</p>
  
  <pre><code>NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@",@"itms-services://?action=download-manifest&amp;url=",self.plistURL]];
  [[UIApplication sharedApplication] openURL:url];
  </code></pre>
  
  <p>My problem is that that the .plist is located in an area on the server where the user has to enter user credentials to access it. So when I execute this code, the user is asked for the credentials in Safari. But I don't want that. I want the app to enter the credentials.</p>
  
  <p>I already tried to open the custom url scheme with an AFNetworking operation but it seems that it can´t handle custom url schemes because I get the error:</p>
  
  <p><code>"Unsupported url"</code></p>
  
  <p><strong>So my question is:</strong> is there any way to use itms-services with user credentials or is there a workaround?</p>
  
  <p>I also considered that maybe downloading the plist and executing it from an internal url could solve the problem, but I wanted to make sure that there is no easier way.</p>
  
  <p>Thanks for reading my question!</p>
