问题
I am just curious to learn if I can send file from one ios device to another using wifi or 3G network. I am not sure this is possible or not.
I gone through apple's documentation of CFNetwork reference and I found cfftp reference. I am not able to understand it clearly as it is saying that we can implement read stream from remote server.
I want to read file from one device to another device and write the same using wifi of both devices same as the way we can do using Bluetooth.
- Is it possible to send file using wifi and 3G network by connection only 2 devices? (No mediator)
- Am I looking for right direction?
- If no please guide me to right direction.
- Is there any class for wifi and 3G file transfer in ios?
thanks in advance.
回答1:
To do transfers between two devices without a mediator, at least one device must run some kind of a server (like http://code.google.com/p/ios-ftp-server/, for the client see SimpleFTPSample). But then you also need to discover ip addresses (maybe with ZeroConf). A lot of hassel, if possible at all; both clients must be in the same network and therefor won't work on 3G.
If you are ok with a mediator, things get much simpler. I have created an Open Souce App called cross copy which uses http REST commands to transfer files between devices (and hence also provides a web app for the desktop). Obviously there are other nice mediator-based solutions: DropBox, Bump, Hoccer, etc
