Appirater doesn't work for me? Although I followed the instructions and doublechecked

I want my app to ask the user to rate/write review in the app store, thats why I tried to implement Appirater from Arash Payan. But it simply doesn't work - no warning is shown, doesn't matter how often I try.

What I did:

• downloaded Appirater from https://github.com/arashpayan/appirater/

• followed theses steps provided in the ReadMe:

  1. Add the Appirater code into your project
  2. Add the CFNetwork and SystemConfiguration frameworks to your project
  3. Call [Appirater appLaunched:YES] at the end of your app delegate's application:didFinishLaunchingWithOptions: method.
  4. Call [Appirater appEnteredForeground:YES] in your app delegate's applicationWillEnterForeground: method.
  5. (OPTIONAL) Call [Appirater userDidSignificantEvent:YES] when the user does something 'significant' in the app.
  6. Finally, set the APPIRATER_APP_ID in Appirater.h to your Apple provided software id.

I also changed the alert message, because my language is not english. I changed the times of use to 5 times...

What did I do wrong/how can I fix it? Thanks a lot!

I have no idea why, but after doing a software update to my iPhone, cleaning the project MANUALLY, it worked again!
