ios - Correct implementation of opening storyboard view controller from UIApplicationShortcutItem in objective-c -


this code have got trying open view controller storyboard. getting error "expected identifier" on

uinavigationcontroller controller = [(uinavigationcontroller)[[mainstoryboard instantiateviewcontrollerwithidentifier: @"arviewcontroller"];

can please help.

- (void)application:(uiapplication *)application performactionforshortcutitem:(uiapplicationshortcutitem *)shortcutitem completionhandler:(void (^)(bool))completionhandler {  nslog(@"%@", shortcutitem.type); if ([shortcutitem.type isequaltostring:@"add own string here"]) {      uinavigationcontroller *navigationcontroller = (uinavigationcontroller *)self.window.rootviewcontroller;     uistoryboard *mainstoryboard = [uistoryboard storyboardwithname:@"main" bundle: nil];     uinavigationcontroller *controller = [(uinavigationcontroller*)[[mainstoryboard instantiateviewcontrollerwithidentifier: @"arviewcontroller"]];     [navigationcontroller pushviewcontroller:controller animated:yes];  } }  @end

the amount , locations of [ , ] didn't match (two [ many, 1 ] many). should be:

uinavigationcontroller *controller = (uinavigationcontroller*)[mainstoryboard instantiateviewcontrollerwithidentifier: @"arviewcontroller"];
