为什么我的 Tabbar 的用户交互在从 popviewcontroller 到另一个视图时启用？

Question

请检查我的代码哪里有错。

第一次启动我的应用时一切正常

tabBars.tabBar.userInteractionEnabled=NO;

此代码工作正常意味着我的标签栏用户交互已关闭。但是我会转到另一个视图并简单地使用 popViewController 并首先查看我的 userInteraction 已启用，为什么？我找不到这个问题。

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];
    objEAScanLeadsVC.delegate = self;
    objEAScanLeadsVC.tabBarItem.titlePositionAdjustment = UIOffsetMake(0.0, -3.0);
    if (IS_IPHONE6PLUS) {

        objEAScanLeadsVC.tabBarItem.titlePositionAdjustment = UIOffsetMake(0.0, -12.0);

    }

                                                forState:UIControlStateSelected];

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






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


    tabBars.viewControllers = localViewControllersArray;

    return [[EABaseCenterVC alloc]

Answer 1

iOS 和其他第 3 方组件具有一些内置行为，可以在 viewWillAppear 或类似的东西上启用它。试着把你的线

tabBars.tabBar.userInteractionEnabled=NO;

在

- (void)viewWillAppear:(BOOL)animated

或

- (void)viewDidAppear:(BOOL)animated

的视图中您想要禁用

的交互

Answer 2

你上面的代码是否在viewDidLoad()中，如果是，那么将其从那里移除并添加到viewWillAppear()中。

试试吧，也许对你有用。

Answer 3

添加此代码可能会有帮助。

- (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];
}
