Using Autolayout to Center Three Objects

Question

Using Autolayout to Center Three Objects

I have a view containing three labels.

The first mark is located at the very top. The third mark is placed 50 pixels below.

What I'm trying to do always puts the second mark in the center of the two using autostart, but I can't figure out how to do this.

The problem is that the second mark is not in the center of the view.

I tried to set the two vertical spacing limits to less than or equal to the initial value, but that didn't work.

Can this be done only with autorun? I was thinking of adding another view, but that doesn't seem like a good solution.

Thank.

, ; layoutSubviews ( viewDidLayoutSubviews, UIView), 2 1 3 ( [super layoutSubviews]).

EDIT: .

- (void)layoutSubviews {
    [super layoutSubviews];

    _label2.center = CGPointMake(_label2.center.x, (CGRectGetMaxY(_label1.frame) + CGRectGetMinY(_label3.frame)) / 2);
}
