I have the following code:
CGImageRef cgImage = [originalImage CGImage];
I know that CGImage is a read-only property of UIImage class.
Does the line
free originalImage's memory?
I'm tracing down a bug in my program and this line seems to be a hot candidate if I'm trying to access originalImage later.
I've found the answer myself: Because the call
CGImageRef img = [[UIImage imageNamed:@"pic.png"] CGImage];
does not contain one of the words create, copy or alloc, I am not responsible for freeing this memory.
