ios - Error when presenting different storyboard programmatically -

-

i have app 2 storyboards. 1 of them main app stuff, , 1 setup storyboard set user profile. right now, have set main interface setup.storyboard. in first view controller in storyboard, in -viewwillappear:animated method, checks nsuserdefault see if setup complete. if is, execute code.

- (void)viewwillappear:(bool)animated {     [super viewwillappear:animated];      if ([[nsuserdefaults standarduserdefaults] boolforkey:@"userhascompletedsetup"]) {          uistoryboard *sb = [uistoryboard storyboardwithname:@"main" bundle:nil];         swrevealviewcontroller *vc = [sb instantiateviewcontrollerwithidentifier:@"initialvc"];         [self presentviewcontroller:vc animated:yes completion:null];     } }

i error warning: attempt present <swrevealviewcontroller: 0x7ff20a595220> on <mposetuponeviewcontroller: 0x7ff20a720b80> view not in window hierarchy!

(i using swrevealviewcontroller in app menu.)

i error, , view controller not switch. there way can switch storyboards based on nsuserdefault? maybe in appdelegate?

just move code viewdidappear:. in viewwillappear:, view not in interface yet (that "will" means), there nothing present from.
