I am trying to build a map based app on iphone. Can the standard pins be replaced by other similarly sized icons?
Yes they can. Set the image property of the MKAnnotationView.

Do you see the cameraOverlayView at all? set the background color to red or something: cameraOverlayView.backgroundColor = [UIColor redColor];
If you don't see the cameraOverlayView at all, then probably you need to set reader. showsZBarControls = NO which will disable the the default controls and use your custom overlay.
If you do see the cameraOverlayView, then the label is probably outside the bounds. Play around with the origin points and get it into position.
BTW I see you're not using ARC, make sure you release instructionLabel!
I have an IOS app in which a custom image is loaded in a view. I want the image to have
the same look and feel, the glossyness, roundness that we find on the Iphone/Ipad home screen
for different apps.
How can I get that effect for a custom image ? Is there any api for that ?
Is it possible to handle the animation of moving icons in an iPhone application? If so, how?
As far as I know, you cannot. The icon motion animation is generated by iOS based on the still icon, and you have no control of it.
I think without .gif image you can not make animated icon and ios will not support that so you have no control on it.
I am trying to create an active image, similar to an image map but capable of zooming in and out using iPhone SDK
What you probably want is a UIScrollView containing a UIImageView and with clickable areas implemented with UIButtons in "custom" mode.
I need to show barcode string(example :1001847983) into barcode image in A UIView. Does the iPhone SDK supports barcode fonts?
I don't need reading the barcode, I just want to show the string in barcode lines.

Can I embed a custom font in an iPhone application?
Then find yourself a barcode font

No, there is no built-in way to display barcodes. You'll have to create a custom view to convert and display them yourself. Simplest way would probably be to make each black line an opaque, empty UIView and add a lot of them with the correct frames to a UIView subclass.
