change NSTabViewItem from other NSView

i have little problem, want change view of nstabview tab view...if create action with

code:

selectnexttabviewitem

on window controller (where define nstabview outlet) work perfectly...if this

code:

appcontroller *controller = [[appcontroller alloc] init]; [controller.tabview selectnexttabviewitem:nil];

also if do

code:

- (void) next {     [self.tabview selectnexttabviewitem:nil];  }     appcontroller *controller = [[appcontroller alloc] init];     [controller next];

where error?

 

are sure want creating new appcontroller object? think you'd wanting access exiting appcontroller object.
