Necesito ayuda en Bump Api enviando imágenes

Question

necesito ayuda aquí. Me gustaría transferir imágenes Jpg o PNG de un iPhone a otro a través de Bump. Me encontré con el éxito y el fracaso donde las imágenes no se envían en absoluto.

a continuación son un archivo NSObject que se llamará cuando el usuario seleccione una imagen de UIimagepicker.

el receptor no enviará ningún dato, solo lo recibirá.

Por favor, ayúdame a echarle un vistazo al código y darme cualquier comentario o punto.

agradecemos y apreciamos su ayuda.

He encontrado que la transferencia de imágenes, o cualquier cantidad de datos por encima de ese límite de 256k, a través de Bump es muy LENTA. Tienes que reventar la carga en pedazos y luego hay un retraso entre cada envío y recepción. Si usted tiene su propio servidor web aquí es lo que haría:

1. tengan la aplicación subir la imagen a su servidor web a través de algún tipo de servicio web
2. tener el servicio Web devuelve un ID o ruta de acceso al archivo subido
3. bulto que se INFORMACIÓN SOBRE que es sólo unos pocos k en el mejor de
4. tengan la parte receptora de la aplicación buscar a la imagen de su servidor web

¡Se sorprenderá de cuánto más rápida será su transferencia!
