Question

I am calling [array addObjectsFromArray:dictionary.allValues]
Will each copied object have retain count incremented for it?
My understanding that when I do [array addObject:obj] , it will retain obj for me untill I delete obj from array or release array itself. Was wondering if its the same with addObjectsFromArray

Thanks.

NSMutableArray memory management

Regarding the object creation methods, all of the convenience methods (array:, arrayWithObjects:, arrayWithArray:, etc.) return autoreleased objects. However, their corresponding init methods (init:, initWithObjects:, initWithArray:, etc.) do not – if you call them, you are responsible for calling release on the returned object
