If the other application is developed by you, you can use custom URL schemes to determine whether a specific version is installed.

For each version that you want to check against, you'll have to add a URL scheme to your other app. The idea is that the URL schemes only contain a URL scheme for the current and previous versions.

Version 1.0 would only have com.you.your-other-app.1.0.
Version 1.2, however, then has two or more URL schemes: com.you.your-other-app.1.0 and com.you.your-other-app.1.2.

You can then check if a specific version of that app is installed in any app using the following:

BOOL is10Installed = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"com.you.your-other-app.1.0://"]];
BOOL is12Installed = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"com.you.your-other-app.1.2://"]];

Update:
I use this in two of my apps that communicate between each other in order to determine whether a specific feature is supported or not. This can be quite useful.

You're in a App Sandbox. You can't communicate with other apps than yours.

To get the Version of your running app:

[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]
