ios how to draw a line on a image in drawrect method

Question

I have a UIImageView called imgView which was added by

[self.view addSubview:imgView];

when I draw line in view's drawrect method, the line shows below imgView, but i want it shows on imgView. ps: i also tried

 [self.view insertSubview:imgView atIndex:0];

which hides the imgView i.e I could see it on the view

[self.view addSubview:imgView];

and

[self.view sendSubviewToBack:imgView];

that also didn't work.

What could be wrong?

Draw your image in the drawRect method, then draw the line.

[img drawAtPoint:your_point]; // Code to draw the line

I know it's late, but still, could be usefull to someone.

The reason why line is under image - is because everything you do in drawRect, will be below every subview. So if you would want a line on top of image, you would need to add to imageview an UIView subview class, in which You have corresponding drawrect with line drawing.
