unarchiveObjectWithFile retain / autorelease needed?
- by fuzzygoat
Just a quick memory management question if I may ... Is the code below ok, or should I be doing a retain and autorelease, I get the feeling I should. But as per the rules unarchiveObjectWithFile does not contain new, copy or alloc.
-(NSMutableArray *)loadGame {
if([[NSFileManager defaultManager] fileExistsAtPath:[self pathForFile:@"gameData.plist"]]) {
NSMutableArray *loadedGame = [NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForFile:@"gameData.plist"]];
return loadedGame;
} else return nil;
}
or
-(NSMutableArray *)loadGame {
if([[NSFileManager defaultManager] fileExistsAtPath:[self pathForFile:@"gameData.plist"]]) {
NSMutableArray *loadedGame = [[NSKeyedUnarchiver unarchiveObjectWithFile:[self pathForFile:@"gameData.plist"]] retain];
return [loadedGame autorelease];
} else return nil;
}
gary
