Question

So I have a question about auto-release pool. I created one use it as following:

dispatch_async(dispatch_get_main_queue(), ^{
            NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
            NSMutableAttributedString * attributedString = [NSMutableAttributedString attributedStringWithString:object.text];
            [attributedString setFont:[UIFont fontWithName:@"HelveticaNeue" size:15]];
            [self.titleLabel_ setAttributedString:attributedString];
            [self.titleLabel_ setLinkColor:self.textColor_];
            [self parseTagsInComment];
            [pool release];
        });

Is this a wrong use of an auto-release pool because I already have an auto-released object?

Answer 1

YES this is right. All the autoreleased objects within the pool will get release message after [pool release];
Thus flushed from the memory if their retain count becomes 0 as in your case NSMutableAttributedString and UIFont will be released.
