Question

Did a simple application for line drawing with UIBezierPath, but now need a way to erase the line drawn with UIBezierPath. Is there a way to implement eraser feature for removing the line painting?

Answer 1

If you are using an image as background then you can set the same image as brush pattern to draw the bezierpath it will virtually give you the eraser effect. It works for me. 🙂

    brushPattern=[[UIColor alloc]initWithPatternImage:[UIImage imageNamed:@"image.jpg"]];
    // Here image.jpg is you background image
