如何实现具有固定右边距和灵活左边距的UIView？

Question

I want to make a view with fixed width, fixed right margin, and flexible left margin. From the document, I chose to use UIViewAutoresizingFlexibleLeftMargin , but it presents flex margin left proportionally meanwhile flex margin right, and fixed width. That is not like what the document says, How can we make a UIView with fixed right margin and flexible left margin and fixed width? Thank you!

Answer 1

In the documentation it says:

UIViewAutoresizingFlexibleLeftMargin
The view resizes by expanding or shrinking in the direction of the left margin.

I suppose you are not expecting the view to resize, but with this flag it will to precisely that.

In fact, your problem has nothing to do with resizing, because you do not want to resize the view. Instead you should make sure the frame.origin.x is set properly by overriding layoutSubviews .

Answer 2

The correct way to do this is using AutoLayout in interface builder, without any code.
