Question

i have a UILabel (name : lbl) and a UIView , except main view (name : myView)
i added my label to myView as subview

now ! i want to get the position of the label in main view ! not in myView

this is my project :

http://www.mediafire.com/?w63bnurf28n8cnb

i dont want to use this code :

CGPoint pos;
pos.x=myView.frame.origin.x+lbl.frame.origin.x  ;
pos.y= myView.frame.origin.y+lbl.frame.origin.y ;

because if i want to rotate the myView using CGAffineTransformMakeRotation this code does not work !

i want position of the label in main view !!

Answer 1

UIView has methods build in for converting points up and down the view hierarchy 🙂 Either of these should do the trick.

    [mainView convertPoint:lbl.center fromView:myView];
    [myView convertPoint:lbl.center toView:mainView];
