tabBarController set to nil when changing view but always in the window


I'm currently using a tableview inside a navigation controller, inside a tab bar controller. When i'm on the detail view of the table view, i want to "swipe" between Detail view, so i have implemented a UISwipeGesture with UIViewAnimations to swipe right/left. Everything is working, but I have a little problem... When i'm on a Detail View loaded from the table view, the self.tabBarController element is here, i have my tab bar so i can add an actionsheet on it. But when i swipe, the self.tabBarController is nil now... I don't know why... Maybe because of the navigation Controller ?

Here is my code :

- (id) init
{
    if (self = [super init]) {
        CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
        UIScrollView *scrollView=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, fullScreenRect.size.width, 367.)];
        scrollView.contentSize=CGSizeMake(320,100);
        scrollView.delegate = self;
        self.view=scrollView;
        self.myView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 367.)];
        self.ButtonSizeM.tag = 0;
        self.ButtonSizeP.tag = 0;
        self.ContentIV = [[UIImageView alloc] init];
    }
    return self;
}

- (void) handleSwipeLeft {
   if (!((self.ancient.tableView.indexPathForSelectedRow.section == ([self.ancient numberOfSectionsInTableView:self.ancient.tableView] - 1)) && (self.ancient.tableView.indexPathForSelectedRow.row == [self.ancient tableView:self.ancient.tableView numberOfRowsInSection:(self.ancient.tableView.indexPathForSelectedRow.section)]-1)))
    {
        NSIndexPath *whereToGo;
        if (self.ancient.tableView.indexPathForSelectedRow.row == [self.ancient tableView:self.ancient.tableView numberOfRowsInSection:(self.ancient.tableView.indexPathForSelectedRow.section)]-1) {
            whereToGo = [NSIndexPath indexPathForRow:0 inSection:(self.ancient.tableView.indexPathForSelectedRow.section)+1];
        }
        else {
            whereToGo = [NSIndexPath indexPathForRow:(self.ancient.tableView.indexPathForSelectedRow.row)+1 inSection:self.ancient.tableView.indexPathForSelectedRow.section];
        }

        CCFASimpleDetail *nextView = [[CCFASimpleDetail alloc] init];
        nextView = [self.ancient tableView:self.ancient.tableView prepareViewForIndexPath:whereToGo];
        [nextView performSelectorOnMainThread:@selector(affichageEnPlace) withObject:nil waitUntilDone:YES];

        float width = self.myView.frame.size.width;
        float height = self.myView.frame.size.height;

        [nextView.view setFrame:CGRectMake(width, 0.0, width, height)];

        [self.view addSubview:nextView.view];
        [UIView animateWithDuration:0.5f delay:0 options:UIViewAnimationCurveEaseInOut animations:^{
                [nextView.view setFrame:self.view.frame];
                [self.myView setFrame:CGRectMake(-width, 0.0, width, height)];
            } completion:^(BOOL finished) {

                [self.myView removeFromSuperview];
                [self.ancient.tableView selectRowAtIndexPath:whereToGo animated:NO scrollPosition:UITableViewScrollPositionTop];
            }
         ];
    }
}

I you could help me to find my tab bar after swiping :) ?


Solution

  • I just solved my problem by adding

    [self.ancient.navigationController popViewControllerAnimated:NO];
    [self.ancient.navigationController pushViewController:nextView animated:NO];
    

    on the completion block !
