all,
I got most of my app done... major problems worked out down to 2 problems but the first one is kicking my rear end all over the place.
I am trying to get a tableview to populate with JSON data and can get the screen to give me the table with the keyboard (which is a whole another problem) but I can't get it to populate the screen with my json data so that I can move on the didselectrow process for the next view controller because I can't get the screen to count my array and then populate it with the data that I need it to in order to move on. I have done several different tutorials on youtube and can get them all to work now I am just trying to put the pieces together in order to make my app work the way that I need / want it to in order to move on.
DevicetableView.h
DeviceTableView.m
I finally got the system to pass the variables from one controller to the next and I appreciate all the help that you guys gave me on that,so that now works so that I can build my json URL string properly with auth but this me and my partner have been beating our heads against the wall and running in circles just confused.
thanks in advance
