Answer 1

You can use the ImageIO Framework like explained in QA1654:

To access the image properties you:

1. create a CGImageSourceRef for your image.
2. get a copy of the image properties dictionary by calling CGImageSourceCopyPropertiesAtIndex.
3. access the values in the dictionary by calling CFDictionaryGetValue with the property key that you are interested in. The available keys are located in the CGImageProperties Reference.
