How to get UIImageView program codes?

I want to get the coordinates of a UIImageView programmatically. How to do it?

For example, I have a square. I want to get the coordinates of all angles. How should I act?

NSLog("%f", ImageView.frame.origin.x); NSLog("%f", ImageView.frame.origin.y);

I get the stupid coordinate of the square.

I have to say that the square (image) rotates and therefore I have to get its coordinates.

Coordinates in coordinate space?

Each UIView has its own coordinate space. You can refer to the size of the view in your own coordinate space by requesting its bounds .

The size and position of the view in the parent view is called frame . In your example, you request the top left corner of the image in its coordinate space of the parent view.

If this is what you want to do, try the following:

 frame.origin.x frame.origin.y frame.size.width frame.size.height

Adding them together, you can get any coordinate: for example, the x coordinate of the upper right will be

 frame.origin.x + frame.size.width
