we need a native app for ios (in the following text named native-app), this app has to register and save the login (to do it has to use servlet invocation) and launch an url corresponding to an html app.
The native-app has to provide to the html-app the following services: 1) open map 2) open camera and save photo using a servlet.
Moreover 3) the native-app has to call a servlet to get any messages to show as notifications on the mobile phone and 4) has to permit the login (verifying against a servlet) and store locally the account and expose a link "forgot password ?" which get an email and invoke a servlet to renew the account.
We have develope a similar native-app for android and in order to achieve the points 1) and 2) we did in this manner: we create customized url photo:// and map:// used in the html-app; the native app act also as an html listener and when it sees map:// (with coordinate as arguments) open the map and when it sees photo:// (with parameter to invoke the servlet telling where to put the photos taken) open the camera and save the new photos using a servlet, at the end invoke a js method in the current html-app page to tell that upload is finished.
We don't know if in iOS is possible to work in the same manner, but we need points 1) 2) 3) 4) and support to publish the native-app (we already have an apple developer account) and availability for future needings. The code has to be well commented and understandable in the case we should modify by ourselves
