如何获取UIImageView坐标？

Question

I have to calculate an angle beetween two UIImageView and i don't find how to get the UIImageViews coordinates(the four corners coordinates). Is there a property for that?

thanks

Answer 1

You should be able to find any angle with trigonometric functions.

For example, this will find the angle between the centers of two UIImageViews that share a superview:

angle = tan((imageView1.center.y-imageView2.center.y),
            (imageView1.center.x-imageView2.center.x));

It is important that they are in the same superview, otherwise the coordinates will be different. To find angles you need to have an understanding of basic trigonometry .

Answer 2

self.frame将为您提供带有视图坐标的CGRect。
