Ownership regarding to returned Quartz objects
- by huggie
I have recently asked about autoreleasing a returned quartz object:
http://stackoverflow.com/questions/2819548/autorelease-for-cgmutablepathref
Dave DeLong answered my question that there is no autorelease for quartz (or any NS foundation objects) and I should use the Create Rule. However the naming convention on the document says,
The Core Foundation naming conventions, in particular use of the word “create”, only apply to C functions that return Core Foundation objects. Naming conventions for Objective-C methods are governed by the Cocoa conventions, irrespective of whether the method returns a Core Foundation or Cocoa object.
By this account since my function is a message in an objective C object it doesn't seem proper to name it createSomething. I still want to return this object. What's the best way to approach this? Should I use the Get Rule and then have the caller explicitly retain it? But this is not within Cocoa convention. What's the proper way to handle this?
