问题描述
什么时候UIView的bounds.origin不是(0, 0)?
When would an UIView's bounds.origin not be (0, 0)?
本段对我有帮助:
但是它仅描述了我自己设置bounds.origin值时的情况.
在其他情况下，bounds.origin != (0, 0)的值是什么?
But it describes only the case when I had set the value of bounds.origin myself.
In what other cases the value of bounds.origin != (0, 0)?

在大多数情况下，这种情况不会发生.如果您使用宽度和/或高度为负的值初始化视图，则会获得宽度为负X和/或高度为负Y的原点.
In most cases this won’t happen. If you initialize your view with a negative width and/or height, you’ll get an origin with a negative X of the width and/or negative Y of the height.
