Can I launch one app from other app on iPhone

ios, launch, url-scheme

Solution

Yes you can achieve this using custom URL Schemes. See Communicating with Other Apps.

App B will need to register a custom URL Scheme which App A uses to launch B and pass it commands.

The following code fragment illustrates how one app can request the services of another app. “todolist” in this example is a hypothetical custom scheme registered by App B.

NSURL *myURL = [NSURL URLWithString:@"todolist://www.acme.com?Quarterly%20Report#200806231300"];
[[UIApplication sharedApplication] openURL:myURL];

Problem

I want to create app which have to launch another app and run some features in last. I mean my app A call app B and run in B some method. Can I do this? I know that I want to use URL scheme, but can I run some method in another app? Thanks!
