AutoLayout to keep view sizes proportional

Question

I\'m trying to achieve the following:

• I have 2 views in my xib that need to stay 20 pixels off the edge (both sides and top)
• The 2 views that need to

Answer 1

1. Remove the two width constraints in code, or lessen their priorities in IB, otherwise you are over-constrained.

2. Add a constraint to describe the width ratio between the green view and blue view, in code:

   // Assuming the ratio you want is green_view_width : blue_view_width = 1 : 2
   NSLayoutConstraint *c = [NSLayoutConstraint constraintWithItem:greenView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:blueView attribute:NSLayoutAttributeWidth multiplier:0.5f constant:0.f];
   [commonSuperview addConstraint:c];
