I want to Show UIAlertView asking “Save” or “Don’t save” on Back Click to previous view in navigation based iPhone Application.

Should I write it on, ViewWillDisappear of current View ? Is that proper ?
Or any other way ?

    First of blindly showing the UIAlertView for saving. I suggest have a BOOL flag in your code by default FALSE which means data not saved. If the user saved his data then make this flag TRUE. So when the view is about to popViewController then check this flag. If FALSE only then show the alertView.

    If I am not wrong, generally when you are about to pop a viewController, you link it to some button right? in that IBAction method put this check.
