iphone - ModalView slide off screen -


i creating user registration functionality in application , needed direction in how implement it. currently, main screen has sign button. when user clicks sign button, modalview slides bottom , presents user required textfields registration. user fills out form , clicks submit button on top right of nav bar ( added nav bar modalview). when user clicks submit button, modalview "disappear" , display activity indicator while validation takes place. if user registers, activity indicator should disappear , new screen slide in right. if submission failed reason, modal view should "re-appear" information user entered.

right problem hiding modalview during validation , sliding in new screen on successful registration. approaches this?

thanks in advance!

here method creates modalview:

- (void)getsignupview:(id)sender {      signupviewcontroller *signupviewcontroller = [[signupviewcontroller alloc]                                                   initwithstyle:uitableviewstylegrouped];      uinavigationcontroller *navigationcontroller = [[uinavigationcontroller     alloc] initwithrootviewcontroller:signupviewcontroller];     [self presentmodalviewcontroller:navigationcontroller animated:yes];      [signupviewcontroller release];  }

i suggest add activity indicator view navigation controller , set animation no. if validation successful pop out view , add new controller animation set yes.

if unsucessfull pop till root view controller. piece of code suggests aware of method calls so. let me know if need additional code.
