This is tricky to word but I have a view controller (vc1) that contains a container view (I\'m using storyboards). Within that container view is a navigation controller and

1) on VC2 expose a property for passing in a reference to VC1

//VC2.h
#import "VC1.h"

@interface VC2 : NSObject
@property (strong, nonatomic) VC1 *parent;
@end

2) on VC1, pass self into the property exposed in VC2 in your prepareForSegue method after you setup your segue's identifier to "ToVC2". Then pass the reference like so:

//VC1.m
@implementation VC1 
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if([segue.identifier isEqualToString:@"ToVC2"]) {
    VC2 *vc2 = segue.destinationViewController;
    vc2.parent = self;
}
}
