Here is my alternative solution.

Find a UIView as a pivot, set its top layout constraint a fixed vertical space to container's top.

Control-Drag this layout constraint as an IBOutlet, such as

@property (weak, nonatomic) IBOutlet NSLayoutConstraint *topLayoutConstraint;

Finally, just override viewWillLayoutSubviews method of UIViewController like following

- (void)viewWillLayoutSubviews
{
    [super viewWillLayoutSubviews];

    self.topLayoutConstraint.constant = [self.topLayoutGuide length] + YOUR_TOP_CONSTRSINT;
}

All the other views' top constraint are based this pivot view, all done :)
