Is there any difference between CGImageGetWidth(workingImage.CGImage) and workingImage.size.width?

Question

Is there any difference between CGImageGetWidth(workingImage.CGImage) and workingImage.size.width ? Is the first faster or safer? I know that in the second case I get the value directly.

Answer 1

Actually both of them returns the same result. CGImageGetWidth(Image.CGImage) returns the Bitmap image width, Image.size.width returns the UIImage width. If you ask about safe/fast, i think first one will be faster, because it comes from ApplicationServices framework and the second one is from UIKit framework. Hope this helps you..
