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
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 .
