iOS Drawing Bar Chart

[dipaliP]

Hi All
I want to draw bar chart using Xcode 10.5.
I am using Cocoa Touch Application for it. I am confused about how to use NSBezier, as the default framework bundle (iPhone OS2.0sdk) does not contain AppKit framework.

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.

Thank you for reply.

Thank you for reply.
Is there any other way to draw bar chart using Coregraphics or any other framework?????

Have you tried read the documentation? I'm not about to do your research for you.

Maybe a new Forum makes sense: "iPhone Programming for Noobs" or better "iPhone Programming for the lazy ones" or "iPhone Programming Self-Help Group"... There all noobs can ask questions and other noobs may answer them.

Please stop asking questions like "how do I enter text in the Xcode editor" or "How do I start Xcode"? ... Aaah!!!!

You could try building your own bar chart drawing routines using the CG graphics primitives (drawing rectangles, etc.)

Maybe a new Forum makes sense: "iPhone Programming for Noobs"

Apple already has one:
Apple.com > Support > Discussions > Developer Forums > Software Development 101
This is already mentioned in the Sticky FAQ here.

context variable not initializing.
As i am drawing it on view i haven't pushed CGContext.
I think there would be any other way to initialise context variable.

I am using following statement to initialize.
CGContextRef context = UIGraphicsGetCurrentContext();

Are you drawing inside the drawRect method of your view, or drawing to a backing bitmap?

.

 

[dipaliP]

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.

 

[firewood]

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

Is that view visible?

.

 

[dipaliP]

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.

finally solved

The code whatever i wrote that was ok, but i didn't check nib file.
Now its solved........
Thanks everyone for your help...........
