I see... thank you everyone!

The key phrase here is in the link provided by Ken Thomases (I was looking for 
this before I asked question):

No. The "get" prefix is used for return-via-pointer. For example,
-[NSString getCharacters:range].

Usually Cocoa method names drop the “get” prefix, so ideally the name would 
just be “imageWithTag:”.

But yes, there’s no need to say “copy” since you’re not creating copies of the 
images. (And even if you were, you could just autorelease them before returning 
them, so the caller wouldn’t have to worry about releasing them; so you 
wouldn’t need to call it out in the method name.)

question about "read-only" rule for Memory Management

2010-04-26 Thread Philip Mobley 
Assume that an array of images is loaded at the start of the app.  

There are a number of views which will be displaying multiple "copies" of the 
image, but they will be accessing the image array as a read-only property, and 
I do not plan to have these views adjust the reference count for each image.  

Question:  is the BELOW method named appropriately?

- (UIImage *) getImageWithTag:(NSString *)tag;
