使用自动布局使任何视图的宽度等于屏幕宽度

Question

How can I make a view to have the width of the screen view. In Xcode 6 the default "Inferred" simulated metrics for the size is 600x600. When I add the constraints for the view to have the width of the view to be equal to the width of the parent, it keeps the size 600px because I am guessing that it takes the size of the simulated metrics....

How can I have the width to be equal to the screen width? Using "Width Equal" is obviously not an option here. So, what should I do?

Thank you!

删除与宽度相关的任何其他约束，并将前导和尾随设置为0。
