objective c - Segue between UIViewControllers without Storyboard OR XIB -

i have nifty project downloaded github (here) , playing around it. project has no storyboard or xibs whatsoever, , 1 viewcontroller, defined viewcontroller.h file , viewcontroller.m file.

perhaps noob question, can have viewcontroller1.h/m programmatically segue viewcontroller2.h/m without using xibs or storyboards? found lot of code on , elsewhere allowing 1 segue programmatically 1 view within storyboard, 1 xib or scoreboard xib (though not opposite) nothing on how segue 1 totally code-based vc another. code found requires define view in terms of bundle location of storyboard or xib file, want use neither.

note: accepted answer did because of ingenuity/interesting-ness, sake of simplicity ended opting answer same question (mine duplicate appears): ios: present view controller programmaticallly

you can use [viewcontroller presentviewcontroller:anothercontroller animated:yes completion:nil]; present view controller modally.

another alternative use uinavigationcontroller , [viewcontroller.navigationcontroller pushviewcontroller:anothercontroller animated:yes];

the second method work if viewcontroller in stack of navigationcontroller
