Objective-C Question

Why my Tabbar's userinteraction is Enabled when come from popviewcontroller to another view?

Please review my code where i am wrong.

first time when my app is launch every thing is fine


tabBars.tabBar.userInteractionEnabled=NO;


This code is working fine means my tabbar userInteraction is OFF. But i will go to another view and simple use the
popViewController
and come to first view my userInteraction is Enabled why?
I am not able to found this problem.

EATabBarVC *tabBars = [[EATabBarVC alloc] init];
UIImage *tabBarImage = [UIImage imageNamed:@"BottomTabBar.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:tabBarImage];
imageView.frame = CGRectMake(self.view.frame.origin.x, 0, self.view.frame.size.width, tabBars.tabBar.frame.size.height);
[imageView sizeToFit];
tabBars.tabBar.userInteractionEnabled=NO;
[tabBars.tabBar insertSubview:imageView atIndex:0];
tabBars.tabBar.tintColor = [UIColor colorWithRed:136/255.f green:159/255.f blue:186/255.f alpha:1];
tabBars.tabBar.tintColor = [UIColor whiteColor];
tabBars.navigationController.navigationBarHidden = YES;
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:3];

EAHomeVC *objEAHomeVC = [[EAHomeVC alloc] init];




UINavigationController *dashboardNavController = [[UINavigationController alloc] initWithRootViewController:objEAHomeVC];

dashboardNavController.navigationBar.hidden = YES;


EAScanLeadsVC *objEAScanLeadsVC = [[EAScanLeadsVC alloc] init];

}
if (IS_IPADAIR2||IS_IPADMINI) {
objEAScanLeadsVC.tabBarItem.titlePositionAdjustment = UIOffsetMake(0.0, -12.0);

}

[objEAScanLeadsVC.tabBarItem setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor colorWithRed:136/255.f green:159/255.f blue:186/255.f alpha:1],NSFontAttributeName : ROBOTOLIGHT(5.39*2.2)}
forState:UIControlStateNormal];
[objEAScanLeadsVC.tabBarItem setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor whiteColor],NSFontAttributeName : ROBOTOLIGHT(5.39*2.2) }
forState:UIControlStateSelected];

UINavigationController *scanNavController = [[UINavigationController alloc] initWithRootViewController:objEAScanLeadsVC];
//scanNavController.title = @"Scan Lead";
scanNavController.tabBarItem.titlePositionAdjustment = UIOffsetMake(0.0, -3.0);
if (IS_IPHONE6PLUS) {
scanNavController.tabBarItem.titlePositionAdjustment = UIOffsetMake(0.0, -6.0);

}
if (IS_IPADAIR2||IS_IPADMINI) {

}

forState:UIControlStateNormal];
[scanNavController.tabBarItem setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor whiteColor],NSFontAttributeName : ROBOTOLIGHT(5.39*2.2) }
forState:UIControlStateSelected];

[tabBars addCenterButtonWithImage:[UIImage imageNamed:@"TabBarScan.png"] highlightImage:[UIImage imageNamed:@"TabBarScan.png"]];






[localViewControllersArray addObject:dashboardNavController];
[localViewControllersArray addObject:scanNavController];


tabBars.viewControllers = localViewControllersArray;
tabBars.view.autoresizingMask=(UIViewAutoresizingFlexibleHeight);
tabBars.navigationController.navigationBar.hidden = YES;
[tabBars.tabBar setItemWidth:self.view.frame.size.width/3];
[tabBars.tabBarItem setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor colorWithRed:136/255.f green:159/255.f blue:186/255.f alpha:1],NSFontAttributeName : ROBOTOLIGHT(5.39*2.2) }
forState:UIControlStateNormal];
[tabBars.tabBarItem setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor whiteColor],NSFontAttributeName : ROBOTOLIGHT(5.39*2.2) }
forState:UIControlStateSelected];

return [[EABaseCenterVC alloc]
initWithRootViewController:tabBars];

Answer

Add this code its may be helpful.

- (void)viewWillAppear:(BOOL)animated
{
[[[[self.tabBarController tabBar]items]objectAtIndex:0]setEnabled:FALSE];
[[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:FALSE];
}
- (void)viewDidAppear:(BOOL)animated
{
[[[[self.tabBarController tabBar]items]objectAtIndex:0]setEnabled:FALSE];
[[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:FALSE];
}
