ios - loadNibNamed from storyboard -

this scenario: simple app 2 viewcontroller classes , storyboard 1 viewcontroller. viewcontroller 'super' inherits uiviewcontroller , implements -loadview , other view controller, 'sub', inherits 'super'. view controller class in storyboard 'sub'.

in code:

@implementation sosuperviewcontroller - (void)loadview {     self.view = [[uiview alloc] initwithframe:[[uiscreen mainscreen] bounds]];     self.view.backgroundcolor = [uicolor redcolor];     nslog(@"%@=> %@", nsstringfromclass([self superclass]), nsstringfromselector(_cmd)); }  @end  @implementation sosubviewcontroller - (void)awakefromnib {     //outlets lazy loaded self.view not set here     [super awakefromnib];      nslog(@"%@=> %@", nsstringfromclass([self class]), nsstringfromselector(_cmd)); }  @end 

the class view controller in storyboard sosubviewcontroller. when executing app can see -awakefromnib invoked in 'sub' controller , later -loadview invoked in 'super' controller , result screen red set in -loadview in 'super'.

the first question is: there way avoid -loadview in 'super' called letting 'sub' view storyboard?

if using xibs instead storyboards implement -loadview in 'sub' view xib file, like:

- (void)loadview {     self.view = [[[nsbundle mainbundle] loadnibnamed:@"soview" owner:self options:nil] firstobject]; } 

but can't know name of nib file using storyboards, instead need uses nibbundle , nibname properties if set:

- (void)loadview {     if (self.nibbundle && self.nibname) {         [self.nibbundle loadnibnamed:self.nibname owner:self options:nil];     } } 

but crashes:

the second question is: possible load nib using storyboards without xib file?

as curiosity, discovered value of self.nibname vxz-lx-hvc-view-kh9-bi-dss #object id viewcontroller in storyboard#-view-#object id view in viewcontroller# kind of right.

you can't.

loadnibnameis supposed load nib called soview.xib in case.

if want load views, can create view in separate xib files, when we're dealing storyboards, add uiviewcontroller inside them (which of course, can contains custom views).

to instantiate method storybard use method :

[self.storyboard instantiateviewcontrollerwithidentifier:@"mycontrollerid"];
