Do you mean NSBezierPath? I cannot find any reference in the documentation to NSBezier. Anyway you can't use any AppKit classes on the iPhone.

context variable not initializing.
As i am drawing it on view i haven't pushed CGContext.

CGContextRef context = UIGraphicsGetCurrentContext();

I am adding new view in nib file and displaying that view on some event of previous view's control. Its goes fine up to displaying that newly added view but control does not enters into view's drawrect: method.
When i tried it with default view it displays all lines.

Did you send a setNeedsDisplay message to the view instance whose drawRect you want called?
Is that view visible?

I am displaying a view on one view.
When click event occurs on first view i am replacing existing view with another view and i want to draw some lines on newly appeared view.
i called setNeedsDisplay, but its not reaching there in drawRect method.
