Launch OF_IOS_APP from IOS App & come back to the original one

I’ve a general question about IOS OS launching Apps.

The particular case is launching an existing IOS Apps from a OFIOSApp. Vice-versa is also an interesting case: There OF calling internal App like IOS camera or Gallery… and when is finished the particular App, do came back to OF…

I could not try IOS OF examples yet, but I would like to do it soon. Is there any OF example opening another App ? May be iosStoryBoardExample?

If this is possible, once the launched App finishes… Is this going to return automatically to the first one? I’ve listened Android does, so wondering about IOS behavior.
