iphone - Drawing in Custom ScrollView -

-

i'm trying draw in scrollview on top of image using multi-touch. circles drawn, under image. in code create custom scrollview:

@interface appscrollview : uiscrollview {

//objects draw circles nsmutabledictionary *circlesinprocess; nsmutablearray *completecircles;

}

@end

in appscrollview.m override touches commands store touches , add 

    (void)drawrect:(cgrect) rect

method draw circles in scrollview. include

    [self setneedsdisplay]

to display circles. in app controller, declare new custom scrollview object:

    iboutlet appscrollview *scrollview;

later add image scrollview using:

    [scrollview addsubview:myimage];

the image visible, when try draw circles on top of it, drawn under image. let me know if have suggestions?

suggestion: draw image onto scrollview (instead of adding image view subview) , draw circles on top of that.
