Best way to add MANY auto layout constraints?

Question

For an app that has many UI elements, such as the piano keyboard, adding constraints to it using Interface Builder may be complicated. Adding one by one? On no, I can't do that. So is there a better way to add so many constraints? Programmatically?

Answer 1

Yes, there are many examples out there of adding autolayout constraints programmatically. See:

Adding Constraints Programmatically on iOS

or

Swift | Adding constraints programmatically

for example.
