I created a CUSTOM split view (extends a UISplitviewController) in our application so that it would support a smaller left view or a smaller right view.
Guidelines (iOS Human Interface Guidelines)
Avoid creating a right pane that is narrower than the left pane. Although the width of the right pane is up to you, it does not look good to use a width of less than 320 points (which is the width of the left pane).
Avoid displaying a navigation bar in both panes at the same time. Doing this would make it very difficult for users to discern the relationship between the two panes.
In general, indicate the current selection in the left pane in a persistent way. This behavior helps people understand the relationship between the item in the left pane and the contents of the right pane. This is important because the content of the right pane can change, but it should always remain related to the item selected in the left pane.
——-My question is, will my app get rejected in the appstore?. Also take not that I’m displaying a navigation bar on both panes. Because the navigation bar on both panes have a title on it. that’s why I need it
UPDATE- I will continue with this and submit my app after a few months, and inform you if it will be rejected or not. thanks for the replies anyway.
I don’t think so , They have written avoid . I have never heard that apple rejected some app because of their UI design . there are some restrictions on using their custom UI. The popular facebook app uses the chat window on the right hand side … Check here for snapshots
However , If you need 100 % guarantee then you need to mail apple
