I am sending a zip file containing images and text file as an email attachment in ipad. Now my required functionality is that I want to launch my app when user taps on attachment for downloading and save the zip file in documents folder of app. How can I accomplish this task?
You cannot launch your iPhone/iPad Application by clicking on the attachment link in email. However, you can open your app by setting custom URL for your app.
For more information on setting custom URL for your app, you can check the question below, May be this way you can achieve your target :

I'm specifically looking to see if SugarWod has implemented a Custom Url, and if so, what it is. They have no developer documentation available and their support has yet to respond back.
If that's unknown, is there a list of sites that currently implement a Custom Url, so that another iOS app can open it?
Or is there a way to see find the Custom Url of an app, if it exists, from your device, iTunes, etc?
Thanks a lot.
It supports a custom URL which starts with sugarwod://
You can easily find this out for any app you have the IPA file of.
1. Rename the extension of the app from .ipa to .zip
2. Extract the zip file
3. Go to the Payload folder of the app
4. Right click on the single file there and choose "show package contents"
5. Open the Info.plist in Xcode and look for the URL types
If there are supported URL's, they can be found there.

I need to select the file which is downloaded through mail. That text document need to be loaded into my app.
Is there any chance to do?
Apps on iOS are sandboxed, so they can not access any files outside of there own sandbox.
There is no user accessible file system thus you can not select a file that is downloaded through mail.
There is the option to allow your app to open files, by extension. You register your to, for example open txt files. Then when you have a txt file in your mail you wil be prompt that you can open the file in your app.
You can find all you need in this Apple document: Registering the File Types Your App Supports
Only if declare that your application can handle that document type then the user will get the chance to open the file with your app When they select from the mail app. This will call delegate method from you app where you can do with the file as you wish.
First you need to declare to the iOS system that your application can handle that file type.
you do this by adding by adding key:values to your applications-info.plist
This guide is what you need to follow

I would like to know if it is possible to let another iOS app open a file my app has created and then the other app edits and saves it just in the original location where my app had saved it at creation time. Or, instead, are files opened with the NSUrl in UIApplicationLaunchOptionsURLKey just read-only so they just can be saved in the other app sandbox?
You can't edit other apps sandbox, it's private to your own app (except for the Documents folder, that a user can access from iTunes).
You also don't have access to the file system of the phone.
Welcome to iOS :)
The best way to achieve this is a custom URL scheme. The other option would be iCloud, but I think the URL scheme is the way to go here.
Edit I see the link doesn't work correctly, not sure why, just scroll the page down to the Communicating with Other Apps paragraph.
I have a problem that PDF file editing . From my app, when an OpenIn menu is shown, I'll choose an application to open the file PDF Expert in iphone device( ex:UIDocumentInteractionController to share with PDF Expert) and the PDF file is opened for edit in PDF Expert. But after editing, how can I send it back to my app or get the link where that editable PDF is saved ? How can I get this file?
You can't, unless you app registers it self that it can also open PDF file. Then if PDF Expert has an option the open the file in an other app the user will be able to open it your again.
There is not build in feature in the iOS SDK that lets you get a file from an other app.
