Answer 1

The only way I know to start external application is to use UIApplication openUrl. The documentation says

An object representing a URL (Universal Resource Locator). UIKit supports the http:, https:, tel:, and mailto: schemes.

If you meant e-mail application, you can pass link according to mailto: scheme. The simplest example is @"mailto:[email protected]".

Answer 2

You need to use -[UIApplication openURL:]. For example, you can use

[[UIApplication sharedApplication] openURL: [NSURL URLWithString: @"http://www.stackoverflow.com"]]

Note this will also switch to the new app. An application can register the URL schemes it supports using its plist.

thanks a lot for your response.
