title: iOS taking photo programmatically
body: <p>I know this is possible, saw this in some apps (iGotYa is I believe the most famous).
  I know how to set up everything for taking photos, saving it and everything.
  But how can it be done programmatically? just having the user click some button (in the regular view controller) and it will automatically take a picture using the front camera and saving it (or not, just getting it as a UIImage)</p>
  
  <p>Thanks!</p>
