Ho bisogno di aiuto su Bump Api che invia immagini

Question

ho bisogno di aiuto qui. Mi piacerebbe trasferire immagini Jpg o PNG da un iPhone a un altro tramite Bump. Ho riscontrato il successo e il fallimento in cui le immagini non vengono inviate affatto.

di seguito sono un file NSObject che verrà chiamato quando l'utente ha selezionato un'immagine da UIimagepicker.

il destinatario non invierà alcun dato ma riceverà solo.

per favore aiutatemi a dare un'occhiata al codice e datemi qualsiasi commento o punto.

grazie e apprezzato il vostro aiuto.

Ho trovato che il trasferimento di immagini, o qualsiasi quantità di dati oltre il limite di 256k, tramite Bump è molto lento. Devi sbrogliare il carico utile in blocchi e poi c'è un ritardo tra quando ogni blocco viene inviato e ricevuto. Se si dispone di un proprio server web ecco cosa farei:

1. avere l'applicazione caricare l'immagine sul server web tramite una sorta di servizio web
2. avere il servizio web restituire un ID o un percorso per il il file caricato
3. urto che INFORMAZIONE sU che dista solo pochi k nella migliore delle ipotesi
4. Avere la parte ricevente delle app recuperare l'immagine dal vostro web server

Saresti stupito di quanto sarà più veloce il tuo trasferimento!
