title: Best way to save UIImages in Core Data
body: <p>I'm looking for the best way to store multiple images in one core data object. I tried to store a UIImage object in Core Data directly. Works fine!</p>
  
  <p>Nevertheless, I read in some forums to transform the UIImage data to PNG and store it as binary data. On my iPhone 5s this was very slow.</p>
  
  <p>What are the pros and cons? Are there any other solutions?</p>
  
  <p>Thanks!</p>
