Come verificare la versione dell'app e richiedere l'aggiornamento degli utenti?

Question

Come posso verificare se l'utente ha la versione corrente della mia app e anche far apparire un messaggio per richiedere loro di aggiornare la versione dell'app?

Qualcosa di simile a quello che vedresti qui sotto.

Answer 1

È necessario disporre di un servizio Web sul server (o qualcosa di simile) che le vostre richieste app all'avvio, per sapere quale è l'ultima versione disponibile. (Se non hai ancora un WS e non vuoi implementarne uno, puoi anche semplicemente usare un file XML o di testo che contiene anche la versione)

Quindi confronta questa versione recuperata dal tuo server con la versione corrente dell'applicazione, utilizzando [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"].

Se sono diversi, è possibile visualizzare l'alertview e reindirizzare a itms-apps://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=[APPID]&mt=8 (sostituendo APPID con il tuo ID iTunes Connect App), che è il collegamento che renderà il vostro iPhone aprire l'applicazione AppStore direttamente sulla pagina di aggiornamento dell'applicazione

Answer 2

Un mio amico ha appena lanciato un servizio, CleverStork, che fa esattamente quello che vuoi.

Non l'ho usato da solo, ma la mia comprensione è che richiede agli utenti - tramite avvisi in-app - di scaricare nuove versioni della vostra app. Offrono piani gratuiti ea pagamento.

Answer 3

di controllare per vedere se avete la versione più recente appena interrogare iTunes per i dati delle app utilizzando la seguente query (nota: cambiare l'id per abbinare l'identificativo del tuo app dalla iTunesConnect):

Ciò restituisce un dizionario JSON che è molto facile da convertire in un NSDictionary da utilizzare direttamente nel codice, quindi tutto ciò che devi fare è estrarre il valore per la chiave "versione" e confrontarlo con il numero di versione dell'app (vedi chiave/valore della versione in grassetto sotto):
