使用乘数进行尾随但不加前导的快速约束

Question

I have the following two texts the Timer constraint works fine. However when doing the complete same with Score just using leading constraint it's stuck.

Anyone has an idea what I'm missing?

Answer 1

Because leading has zero value unlike trailing which = view width , so applying multiplier to zero results in a zero

You can make it with centerX / trailing also

Answer 2

Just change the leading Constrain of Score to Superview.Trailing instead of Superview.Leading :

And then set the Score constraint multiplier to 6.27. I will update the answer with the calculation I made shortly.

UPDATE:

The multiplier of Score.Leading constant to Superview.Traling constant is : multiplier = View.width / (View.width - View.width / 1.2)

In my case the View width in iPhone X is 414

414 / 1.2 = 345

414 - 345 = 69

414 / 69 = multiplier
