the below code

-(void) mapview:(gmsmapview *)mapview didlongpressatcoordinate:(cllocationcoordinate2d)coordinate{ slidervc = [self.storyboard instantiateviewcontrollerwithidentifier:@"sliderviewcontroller"]; slidervc.view.backgroundcolor = [uicolor yellowcolor]; self.modalpresentationstyle = uimodalpresentationcurrentcontext; [self presentviewcontroller:slidervc animated:yes completion:null]; }

code new viewcontroller (.m) only:

when creating new view controller, have instantiate nib file, like:

slidervc = [[sliderviewcontroller alloc] initwithnibname:@"sliderviewcontroller" bundle:nil]

or if utilize storyboards:

slidervc = [self.storyboard instantiateviewcontrollerwithidentifier:@"sliderviewcontroller"];

otherwise there no connection file created in interface builder , ios doesn't know ui elements load view controller.

update: have set string:

ios objective-c uiviewcontroller
