Storyboard warning: attribute of the first base layout before iOS 8.0

Question

I can’t figure out how to get rid of this warning, I use a storyboard with many viewControllers (with shortcuts, text fields and lots of restrictions), they are all created in much the same way.

When I click on the warning, it highlights the UILabel inside the scrollView:

There are many limited UILabels in this scrollView, I tried everything I could find, including: Unavailable attribute: The first attribute of the baseline layout in iOS versions prior to 8.0

This warning does not crash my application, I tried the simulator and iPhone 4 (ios 7.1.2). But I'm worried about approving the AppStore.

I think the problem is that you have a lot of restrictions that use NSLayoutAttributeFirstBaseline , and when you click on the warning, Xcode indicates an invalid restriction.

To define a constraint search in Xcode using "firstBaseline". Change all restrictions that are used by NSLayoutAttributeFirstBaseline .

Note. You may need to customize your views. In my case, NSLayoutAttributeBaseline worked well.
