如何在单击按钮时获取UIImageView的Height，Width，X和Y并将其传递给Other ViewController？

Question

I'm creating an iOS app(objective c) and in this app I'm setting UIImageview (movable) on UIView (like Sticker). What I want to do next is when User click on button that time a new ViewController will open and that time UIImageview should be on same position(same height & width) like it's last position, height and width on previous ViewController . But I don't know how to save position of UIImageview and use it on other ViewController . I know how to use properties from other ViewController but not getting any idea of this specific one.

Answer 1

Write below code in button action method:

// Convert the co-ordinates of the view into the window co-ordinate space

   CGRect frame = [yourImgView.superview convertRect:yourImgView.frame toView:self.view];

Now, frame will be your UIImageview frame in your full viewController view, which you can pass to next viewController and use there.

Answer 2

I Think You just need to pass the Frame of the image view before you create the new controller as property in the controller to set new the image view with that frame.

ViewController1 :

let imageViewFrame = yourimageView.frame

Viewcontroller2 :

var imageFrame : CGRect?

Viewcontroller2.imageFrame =  imageViewFrame

newImageView.frame = imageFrame
