Returning objects from methods in Objective-C

Question

Please explain how to handle returned objects from methods?

Below I get employee details from the GeEmployeetData function with auto-advertisement,

• Do I need to save the returned object in the process method?

• Can I free * emp in a Process function?

  - (void) Process {Employee * emp = [self GeEmployeetData]}

  + (Employee *) GeEmployeetData {

  Employee * emp = [[Employee alloc] init]; // fill the object

  return [emp autorelease]; }

In 99% of cases, you must save objects with auto-implementation returned from other methods if you want to save them.
