i want add one-time, mandatory email sign @ beginning of basic app. so, if user has never used app before, send them "sign up" page enter email, hit "submit" , sent home page of app. if user has opened app before, , therefore entered email, should sent straight app's home page.
how can go this?
also, addition, how can store emails have been submitted through app in spreadsheet or like?
you should use nsuserdefault store status check in appdelegate's didfinishlaunchingwithoption status true in user defaults user have opened app before. if status not true firsttime user.
so, if firsttime set rootviewcontroller signup viewcontroller. , set status true in userdefaults.
if not first time set rootviewcontroller homeviewcontroller.
do stuff in didfinishlaunchingwithoption method of appdelegate got called first when app launch.
that`s it.
