First : Sorry, I cannot put URLs in this post because the forum robot forbids it (it won't let me submit my post, it says "Your post looks too spamy for a new user, please remove off-site URLs.")
This being said, the eyefi URL scheme works. Thanks for that.
I would like now to be able to call back my iOS app. Remember, I want to use Eye-Fi as a background process only (just like Eye-Fi Helper on Windows or Mac OS X)
Let's call my iOS app iPortrait and let's assume i registered a iportrait:// URL scheme.
That would require you to add some code to Eye-Fi app for it to manage a callback action. So for example, if I call from my app
eyefi://action?callback=iportrait, it will open your app and then your app will call my app thanks to the callback value => iportrait://
This is well explained on the first stackoverflow thread if you search "ios-url-scheme-return-to-safari-when-done" on google (remember, I am not allowed to type URLs in this post, LOL !)
I am not a professional iOS dev but technically it seems only a matter of calling a openURL function.
What do you think about implementing this callback action ?
It would mean a lot to me. It would implement the same logic as the Eye-Fi Helper but for iOS.
