objective c - Error Message no visible @interface for UIToolbar declares the selector 'setItems:animated:' -


i'm building uisplitviewcontroller code:

- (void)splitviewcontroller:(uisplitviewcontroller *)svc      willhideviewcontroller:(uiviewcontroller *)aviewcontroller           withbarbuttonitem:(uibarbuttonitem *)barbuttonitem        forpopovercontroller:(uipopovercontroller *)pc {     barbuttonitem.title = @"customers";     nsmutablearray *items = [[self.toolbar items] mutablecopy];     [items insert0bject:barbuttonitem atlndex:0]:     [self.toolbar setitems:items animatd:yes];      masterpopovercontroller = pc; }  - (void)splitviewcontroller: (uisplitviewcontroller *)svc      willshowviewcontroller: (uiviewcontroller *)aviewcontroller   invalidatingbarbuttonitem: (uibarbuttonitem *)button {     nsmutablearray *items = [[self.toolbar items] mutablecopy];     [items removeobject:button];     [self.toolbar setitems:items animatied:yes];     masterpopovercontroller = nil; }

i'm getting same error on 2 different lines: on line

masterpopovercontroller = pc;

and

[self.toolbar setitems:items animatied:yes];

xcode shows me error

no visible @interface 'uitoolbar' declares selector 'setitems:animatd' (or 'setitems:animatied' in second)

how correct this?

enter image description here

replace current code with:

[self.toolbar setitems:items animated:yes];
