iOS Navigation Breadcrumb Trail

Question

Basically, I have a client that wants a breadcrumb trail implemented in the navigation bar. I realize Apple doesn't recommend this behavior, but the app I'm building is for internal use only and won't be submitted to the App Store.

I need something along the lines of what AirVideo uses in their iPad App. Are there any navigation controllers that provide this functionality or any other code available?

Answer 1

I think you'd have to create your own custom View Controller that holds a reference to the other views, and draws the buttons how you want.

Answer 2

I have done similar, but unfortunately I cannot share any code, as it is bound by NDA. But I can guide you for an easy solution.

• Use UIWebView for breadcrumb.
• Use CSS to show your items (like http://www.jankoatwarpspeed.com/examples/breadcrumb/#) which are enumerated from UIViewController stack
• Give links, custom schema linkes, like (controller://1, controller://2 etc)
• handle UIWebView requests, and use popToViewController of UINavigationController to change to selected controller

that's it

hope this helps
