“Auto Layout still required after executing -layoutSubviews” with UITableViewCell subclass

by

I encountered the same problem while manually adding constraints in code. In code, I was doing the following:

{
    [self setTranslatesAutoresizingMaskIntoConstraints:YES];
    [self addSubview:someView];
    [self addSubview:someOtherView];
    [self addConstraint:...];
}

Hypothesis

From what I can tell, the issue is that when you disable translatesAutoresizingMaskIntoConstraints, UITableViewCell starts to use Auto Layout and naturally fails because the underlying implementation of layoutSublayersForLayer does not call super. Someone with Hopper or some other tool can confirm this. Since you’re using IB you’re probably wondering why this is an issue… and that’s because using IB automatically disables translatesAutoresizingMaskIntoConstraints for views that it adds constraints to (it will automatically add a width and height constraint in their place).

Solution

My solution was to move everything to the contentView.

{
   [self.contentView addSubview:someView];
   [self.contentView addSubview:someOtherView];
   [self.contentView addConstraint:...];
}

I’m not 100% sure if this will work in Interface Builder, but if you push everything off of your cell (assuming that you have something directly on it) then it should work. Hope this helps you!
