objective c - Class method that returns object and transfers ownership -

[this memory management clarification/question]

• i have class method returns nsmutablearray*.
• i want caller own , have call release.
• i don't want use autorelease because want freed memory caller done.

is ok long start name new or alloc, correct?

e.g.

+ (nsmutablearray*) newarrayfromdb {   nsmutablearray* myarray = [[nsmutablearray alloc] init];   //stuff populate array   return myarray; } 

then caller call with:

 nsmutablearray* test = [thatclass newarrayfromdb];   //use test   [test release]; 

the static analyzer seems think ok...but wanted second opinion...

thanks feedback....

yes, you're doing correct - you're following rules in object ownership policy correctly.

the point might question i don't want use autorelease because want freed memory caller done. default autorelease pool drained every time through main run loop, in cases memory released anyway. and, if caller needs force release sooner, can allocate/drain autorelease pool manually. of course, 1 approach create 2 convenience methods + newarrayfromdb: , +arrayfromdb; 1 autoreleases , 1 doesn't.
