#1

You can use:

您可以使用:

CGRect smallestRectangle = CGRectUnion(view1.frame, view2.frame);

According to the docs, this function

根据文档,这个功能

Returns the smallest rectangle that contains the two source rectangles.

返回包含两个源矩形的最小矩形。

#2

here are some steps that should work to find the rectangle you want

这里有一些步骤可以找到你想要的矩形

• find the left most origin.x... = new origin.x

找到最左边的origin.x ... = new origin.x

• find the top most origin.y... = new origin.y

找到最顶层的origin.y ... = new origin.y

• find the largest (origin.x + size.width)... = new size.width

找到最大的(origin.x + size.width)... = new size.width

• find the largest (origin.y + size.height)... = new size.height

找到最大的(origin.y + size.height)... = new size.height
