title: ios - Every time application:openURL:sourceapplication is fired, iCloud backup size increase
body: <p>I have an app that opens different files.
  To avoid the app to be reject from Apple, only user data must be backed up on iCloud.
  I have done all to meet "iOS Data Storage Guidelines" requirements.</p>
  
  <p>But I can't resolve this issue:
  Every time the method
  application:openURL:sourceApplication:annotation:
  is fired, the iCloud size for my app increase for exactly the file size.</p>
  
  <p>For testing, now when the openURL method is fired, I simply return YES, so my app do nothing with the incoming URL, but the size still increase.</p>
  
  <p>A summary of what is happening (Example is opening a mail attachment of 3 mb from mail app):<br>
  - Actual size of the app on iCloud: 3Mb<br>
  - Tap on attachment<br>
  - Choose to open with my app<br>
  - openURL event is fired<br>
  - openURL return YES WITHOUT DOING ANYTHING ELSE<br>
  - Actual size of the app on iCloud: 6Mb<br></p>
  
  <p>What I'm doing wrong?</p>
  
  <p>Thanks
  Claudio</p>
