How to plot more plot points in CPTGraph. I want to implement it using NSScrollView. But there is no delegate methods for checking the "scrolling".
Please give me some suggestions for implementing the above.
Do you have to use a scroll view? Core Plot natively supports scrolling. Just set allowsUserInteraction to YES on the plot space. You can set the globalXRange and/or globalYRange to limit the scrolling range. You can also use a plot space delegate to monitor the scrolling and exert more control over the scrolling behavior or perform other actions.

In iOS many control's color property are called tintColor, why not directly use color. By the way, my native language is not English.
Because iOS controls tend to use gradients and other visual effects. So the color you give changes the tint of the various colours used, it doesn't give you the specific color you ask for.

You can use a ground overlay or marker (depending on if you want it to scale with the map or not), but these both use a UIImage, not a UIImageView.

The UIProgressView by default has rounded corners.
How can I get rid of those rounded corners? I wish to have a standard rectangle view.
I have tried progressView.layer.cornerRadius = 0;, but no use.
You have to subclass UIProgressView and override drawRect.
EDIT 08/31/2016:
Here was a tutorial
;-)
Come on: This one is from 2012, the Question is closed, iOS had a few updates and so had the SDK and the ProgressView API, we're (hopefully) using swift now ... and yes: The link is broken. So, feel free to downvote this one, but ask yourself, if a non-broken link would really solve your problem.

I am creating a view based application. I have an image in this app and I have to cut a particular section of the image and animate it little up and down.
How can this be achieved?
set imageview frame and wrirte these two line
[imageview commitanimation]
[imageview setanimationduration:1]
You should duplicated your image and crop it (have a look at this post), then you put the resulting image in a UIImageView or CALayer and animate it as you like.

I want to draw dynamic Pie Chart in Ipad which takes values from database .
Please suggest the way to draw chart ...
See the Drawing and Printing Guide for iOS for specifics on drawing with iOS. Also note, your view won't be taking things from a database. A controller object will get the data from the database, hold it, and tell your view to display it. The view then draws itself to represent the data its controller told it to. This is MVC 101.
