弹出不足以删除视图控制器

Question

I am experiencing an issue and I believe it's due to me incorrectly removing my view. I will try to explain and hope all can follow. I have a UISplitview app which essentially has two views. The main detail view, and a view which is essentially a map. Upon selecting a certain string in the table this code is called (this code is in the detailview but the rainObject is passed in from a UIViewController .

-(void)setReceivedRainObject:(id)receivedRainObject{
    if ([receivedRainObject isEqualToString:@"Test"]){
        mapViewController *mapView=[[mapViewController alloc]initWithNibName:@"mapViewController" bundle:nil location:0];
        [self.navigationItem setHidesBackButton:NO animated:NO];
        [self.navigationController setNavigationBarHidden:NO animated:YES];
        [self.navigationController pushViewController:mapView animated:NO];
    }
}

So the above code loads my map fine in the detailscreen as expected. However, when I click the first option (test) from the left view controller, it calls a new view controller (viewcontroller2 with a row named test2) and that second controller calls a third( viewcontroller3 with a row named test3) On the viewDidDisappear of viewcontoller3 and in the viewWillAppear of test I have this code

 [self.detailViewController.navigationController popViewControllerAnimated:NO];

So when I drill down to viewcontroller, when I click the backbutton, it pops off one map, and when testview loads it pops the second. leaving my detail view showing exactly how I started. However, I've noticed that if I clicked the "test" button twice, and try to go back, there is an "extra screen" that was supposed to be remove with pop. Would like to know how to remove this mass of views or to stop the program from adding so many. Thanks

Just use

mapViewController *mapView=[[mapViewController alloc]initWithNibName:@"mapViewController" bundle:nil location:0];
[self.navigationController pushViewController:mapView animated:YES];

to navigate through the view controllers.
