I am creating app and I need in detail page for item add some bar image buttons to rightBarButtonItems of navigation bar. I know that there are several predefined styles but I am not sure which images to use for share button and for button which runs navigation. How they should look like that user immediately knows purpose. For which use there is action style in predefined styles? Thanks
The Share icon is:
As defined here:
If by "running the navigation" you mean showing other sections of the app/site vs going backwards or forwards (the chevron left or right), then you can use what many applications tend to use which is the three horizontal stacked lines or what some refer to as the "hamburger" button. The "hamburger" button has become synonymous with showing/hiding the navigation options/sections of the app or page. When the user clicks it, a dropdown appears or the screen slides out to reveal different options.
Hope this helps.
There are icons that have been so widely adopted now that they have become useful for situations like this because everyone knows what they mean; though you could just say "Share" in the titlebar and that would to the trick.

As for your other question about navigation you would want a chevron arrow pointing to the left on the left side of your titlebar like this:
