My iOS app is a mobile version of a management program I had developed for a company as a desktop application. So its main tasks are saving data in a database and retrieve them when needed with the option to edit them. So I guess that the GUI is mainly composed by forms to fill in and tables to show data. So I am asking you if you could link me some tutorials or give me some tips on how to realize them in a nice way but not too complex. I'd rather avoid simply creating a blank view controller and inserting labels and text fields without a minimum of criterion. I am very new to iOS and XCode and, as I have not too much time, I am asking directly your opinion instead of spending hours in looking for tutorials.
UPDATE!
I mean that I would like to get something similar, for a mobile iOS device, to the following screenshots (from the desktop application I mentioned above)
