Can I launch one app from other app on iPhone
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!
Answer
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];
