[Question] Syntax problem?

[Lavare]

What is the syntax of the code?

[self addSubview:({

        UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, scrollW, scrollH)];

        [self addSubviewToScrollView:scrollView];

        scrollView.delegate                       = self;
        scrollView.scrollsToTop                   = NO;
        scrollView.pagingEnabled                  = YES;
        scrollView.showsHorizontalScrollIndicator = NO;
        scrollView.contentOffset                  = CGPointMake(scrollW, 0);
        scrollView.contentSize                    = CGSizeMake((self.count + 2) * scrollW, 0);

        self.scrollView = scrollView;
    })];

C++ Lambda syntax? If remove the self.scrollView = scrollView; compiler to the error. The return value is not automatically speculated?

In fact, I don't really know its syntax name, I also think it's a lambda syntax. And we have to return a right value in this func:)

For me, self.scrollView = scrollView; as a return value of the syntax is unfamiliar, can provide information see more? : ]

scrollView;
