Zoom map to display overlay in entire display area - iphone

I have added overlay on map. I don't know how to make map zoom upto certain level so overlay will display over entire display area. Here I need what should be zoom level so my overlay will display in entire display area or any other way to do it. For clarification I don't want to restrict the user to scroll outside of this overlay area.Any help will be appreciated. Thanks in Advance.

Please try the following code
[<mapView> setVisibleMapRect:[<overlayView> boundingMapRect]];
Thanks,

Ideas for custom, zoomable floorplan with interactive markers?

I'm looking to implement a widget that shows a floorplan with a custom image. It needs to have markers that show specific points on the plan, and the markers should pan and zoom with the floorplan so they remain in the same position relative to the plan. Imagine a normal map with markers, but I want to show a floorplan image instead of map data.
I've seen this video which uses a GridView:
https://www.youtube.com/watch?v=RZMqaHSs6CM however I don't think it's the best solution for my scenario, as my floorplan images may have different numbers of markers that won't fit in to the grid resolution/dimensions.
Any ideas which widgets/libraries would help me achieve this?
Please let me know if you want more clarity on my goal
Thanks!

Mall Map Integration into iPhone Application

Hello everyone i am stuck into one problem. I am working on Application in which Mall Map required to integrate.
I need to display Mall map like this:
I have done proper r&d but not found any solution yet.
Can it be possible if yes then how can i implement this ?
Any hint or suggestion will be appreciated.
Thanks.
You could display the map in a UIImage and place this image in a UIScrollView. After that you need to divide the image into region rectangles, each identifying one room.
When the user taps the UIScrollView you need to determine which region he tapped on.
Using your room grid you can detect which room he tapped on. Of course this is easier for not zoomed images.
In a zoomed state you need to convert the touched point to the "unzoomed touched point" and check this point for the grid.

I just don't know where to start from, do I use UIWebView or MapKit?
Any help will be appreciated.

What we did in our app is use a UIImageView on a UIScrollView. You need to take a screenshot of the object you will map on the google-map and precisely draw your overlay over it. Also you need to take the top left coordinate and bottom right coordinate of the screenshot you took from the map. Then put the overlay image inside an imageview, image view on scrollview, and scale your coordinate system on the scrollview with the coordinates you took from the map. Now you can precisely plot POI-s on your overlay. A note: The first thing we did is we overlaid the g-map with custom image view but it was really slow when scrolled, so don't even try it. Good luck with coding.
[EDIT] you take a large screenshot of an area on google map like this

How to do circular scroll view?

I am doing an application in which i have to show a semi circle on which there should be different options in scroll view. That means on that image of semicircle i have to show scroll in circular way .
How can i do that??
Can anyone please guide me ?
You mean you'd need to rotate the contents inside the semi-circle like in a "wheel of fortune" kind of way?
I don't think you can do that with a regular UIScrollView, you'd have to handle the touches and do the rotation yourself.
I'd recommend you start by taking a look at the "Touches" code sample from the UIKit docs:

Zoom Image and store the visible Image

I am working on module where I need to perform following activities.
Select image from Library.
Show that image.
Zoom that image.
Save the Zoomed portion or visible portion on the view.so that final image will get saved with zoomed.
I have covered 1,2,3 and struggling with 4
Does anyone have idea about this?
Thanks,
Sagar
If I understand you correctly, you want to save image that appears on the screen after zooming? To do that you can use CGImageCreateWithImageInRect function.
