Question

Im looking for some help regarding to put a save like confirmation if some changes where made to a UITextField and UISegmentedControl.

Can I prevent the UINavigationController from pop the view? And then pop based on buttons in a AlertView?

I use the UITextField and UISegmented control to POST data to a webservice.

I perhaps need to use a modalView for this? but wanted first to see if someone have another idea, because I would like to keep navigation clicks down if possible.

Any suggestions for this?

Thanks,

Why not just using a UIAlertView?

EDIT: On second thought, and re-reading your question + comment, I would recommend to use a Modal View with classics OK/Cancel buttons + a UIAlertView(s) for confirmation(s). (UIAlertView “poping” on OK/Cancel is easy to do via UIAlertViewDelegate)

That’s what Modal views are for, block UI until some user action has been completed. Like a form. This is how I do all my forms, and how Apple does (just look at the create mail screen for an example, or any form of iOS apps)

Adding a “Magical” action requiring user interaction on the back button of a navigation controller is bad in terms of user experience, if you hit back, you expect the view to pop, nothing else. I would then be surprised if Apple SDK even allows to cancel that event…
