iOS app - Lite version or paid version

Question

In windows phone "App.xaml.cs" file contains the following method to identify whether the app is trial version in Windows Phone app.

private void Application_Launching(object sender, LaunchingEventArgs e)
{
  var license = new Microsoft.Phone.Marketplace.LicenseInformation();
   IsTrial = license.IsTrial(); }

Here IsTrail is the property which returns true or false. Is there any method is available for iOS to detect the lite or Paid version?

Answer 1

There is no concept of trial in iOS App Store. You submit two different apps with different names - lite/pro etc. Since the apps are completely different binaries, you can simply use compile time preprocessor macros to differentiate between PRO and LITE versions.

Eg, in your PRO target, define LITE=0, and in LITE: LITE=1, and in code:

#if LITE
//do something
#else
//do something else
#endif

Just a word of warning: You might want to check Apple guidelines with respect to free/paid apps combo. As @manujmv mentioned, you don't want to use words like "Trial" or "Beta" in your app name. Any app submitted to the App Store should be functionally complete in itself and should be supported without asking user to pay additional $$$ (i.e. no time based expiry).
