ios - Programmatically moving to other view results in black screen -

i'm using code programmatically move main screen (login page) view behind it, gives black screen;

landingcontroller *landingcontroller = [[landingcontroller alloc] init]; [self presentviewcontroller:landingcontroller animated:yes completion:nil]; 

i've included landingcontroller.h file viewcontroller.h , doesn't give errors.

when remove storyboard id landingcontroller (which isn't referred to) in above code, message:

/users/allendar/desktop/ios apps/#hidden# app/#hidden# app/base.lproj/main_ipad.storyboard: scene unreachable due lack of entry points , not have identifier runtime access via -instantiateviewcontrollerwithidentifier:. 

i'm assuming has call associated controller view, whereas doesn't instantiate view's internals.

i tried other examples triggering storyboard id of landingcontroller, either gives errors or nothing (like code does).

any ideas how can invoke view when triggering controller, or either doing through storyboard id?

try this:

    uistoryboard *storybboard = [uistoryboard storyboardwithname:@"yourstoryboard" bundle:nil]; landingcontroller * landingcontroller  = [storybboard instantiateviewcontrollerwithidentifier:@"storyboard id"]; [self presentviewcontroller: landingcontroller animated:yes completion:nil];
