I'm transitioning from an iPhone app to iPad, in the iPhone version I have a view hierarchy similar to this:
That is, an
UITableView, while tapping on a cell the app navigates to another view with it's details. From that view, it's also possible to enable the edition of the current item.
On the iPad, I've a split view that is intended to be hidden when device in portrait, as Mail app does:
I don´t know what following options should be more appropriate, from the point of view using UX and from the point of view of the iOS HIG:
a) A form sheet modal view, similar to the one that is displayed in iTunes for iPad when a movie or another thing is selected. Then, when tapping the "Edit item" button, I don´t know if I'd navigate to the "New Item" form inside that same modal view, or display another modal view on top of this one (in iPhone, such "New Item" form is a modal view):
b) A popover. Then, I don´t know if I should keep the edition form inside the popover, or display it in a modal view:
Another consideration: tapping the image placeholder, a camera view should appear to let the user take a picture. A thumbnail is shown in such placeholder.
Thanks in advance
EDIT: To just display the details of a cell, without having the need to enable an edition mode nor any user interaction, which option should be the best? A modal view, a popover, or a full screen navigation?
