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.

I want to implement a feature in app in which when the user takes a picture through the app, what he sees on the screen is:
the normal viefinder, showing the image the user will capture
an extra layer, not completely transparent probably an alpha of 0.4. this layer consists of an outline of a face. this is so that the user can align his image with the outline.
After this when the user takes the picture all the app does is show just the face(part of the picture inside the outline) with an animated body.
I am not sure if adding that extra layer(point 2) is possible.
also it is not important for the outline to be an outline of a face, could be an outline of a human body instead or of a tree or anything.
Try a little google. You are looking for an overlay.

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.

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.

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 pretty new on this platform. i am working on a project in which i have to perform following task.
1.) show an image on UIIMageView which is selected from photolibrary.(completed.)
2.) take a UILAbel and show the pixel of selected Image. (That's what i want to know who to do.)
3.) save in photolibrary(completed).
Thanks in advance.
HI you said u want to get the area of the image then what about the periperals means by using gestures u want to get measure the area of the image or you want measure someother way please let me know.
if based on finger moments you want to measure the area ok fine you can by using the locationinview method you can find the gesture starting point location values and gesture ending point locationvalues based on these you can find the area.
