Autolayout : Need constraints for y position or height

Question

And my applied constraint is

I am also including sample project here with above issue.

Answer 1

Just one Constraints required

Provide SubHeading label height >= ( Greater than equal to ) Constraints

Because of you have applied aspect ratio of UIImageView of 4:3 so it required to fixed other items height and Y position before it apply a ratio to it. By giving height to subheading Autolayout is able to calculate approx value min required in image ratio

Hope it is helpful to you

Answer 2

I am attaching two images, one is output and another one is the constraints of views (UILabel, UIImageView). For testing purpose, I put long texts in UILabel, after testing I reduced the text to 'Heading it is' and 'Sub heading it is'. Let me know, if its working of not.enter image description here
