i am pushing visit view whenever i press visit button ,but when i press visit button in visit view is gets pushing new view on existing visit view ,so whenever i press back is not getting me to previous view suddenly …
so i want to eliminate these condition
I’m having a hard time parsing that question, but it sounds to me as though you might be looking for the
topViewControllerandvisibleViewControllerproperties of UINavigationController.
