I have never tried the code in the above answer, but the following works for me:

    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"app-scheme://"]] ) {
        NSLog(@"This app is installed.");
    } else {
        NSLog(@"This app is not installed.");
    }

This method requires the app to have a scheme though. I don't know about the one above.

Use NSWorkspace's fullPathForApplication: to get an application's bundle path. If that method returns nil, the app is not installed. For example:

NSString *path = [[NSWorkspace sharedWorkspace] fullPathForApplication:@"Twitter"];

BOOL isTwitterInstalled = (nil != path);

URLForApplicationWithBundleIdentifier is another method you may use.
