Problem
You would like to directly manipulate the array
of view controllers associated with a
specific navigation controller
Solution
Use the viewControllers
property of the UINavigationController class to access
and
modify the array of view controllers associated with a navigation
controller
- (void) goBack { /* Get the current array of View Controllers */ NSArray *currentControllers = self.navigationController.viewControllers; /* Create a mutable array out of this array */ NSMutableArray *newControllers = [NSMutableArray arrayWithArray:currentControllers]; /* Remove the last object from the array */ [newControllers removeLastObject]; /* Assign this array to the Navigation Controller with animation */ [self.navigationController setViewControllers:newControllers animated:YES]; }
