Iphone ViewXcode似乎不工作

海,， 我已经创建了一个基于选项卡的iRestaura项目。我使用5个选项卡栏项。选项卡栏名称之一是Customer。当我点击customer时，会以编程方式使用3 viewcontroller创建另一个选项卡栏。当我使用view didload方法时，tabbarcontroller已成功创建。但当我使用view时，tabbar控制器并不是由tabbar创建的。在这两种情况下，以编程方式创建的其他三个viewcontroller“没有显示视图”都不起作用。但在所有情况下，我都需要使用ViewDidAspect方法。 请任何人都能帮我。。。 下面给出了不起作用的VIEWDIDEDISPENCE方法

- (void)viewDidAppear:(BOOL)animated 
{
    [super viewDidAppear:animated];
    UITabBarController *tabBarController1=[[UITabBarController alloc] init];

    CustomerListViewController *customerListViewController=[[CustomerListViewController alloc] init];
    customerListViewController.title=@"Customer List";
    UIImage *anImage1 = [UIImage imageNamed:@"customer.png"];
    UITabBarItem *theItem1 = [[UITabBarItem alloc] initWithTitle:@"CustomerList" image:anImage1 tag:0];
    customerListViewController.tabBarItem = theItem1;


    SelectedCustomerViewController *selectedCustomerViewController= [[SelectedCustomerViewController alloc] init];  
    selectedCustomerViewController.title=@"Selected Customer";
    UIImage *anImage3 = [UIImage imageNamed:@"selectedCustomer.png"];
    UITabBarItem *theItem = [[UITabBarItem alloc] initWithTitle:@"Selected Customer" image:anImage3 tag:1];
    selectedCustomerViewController.tabBarItem = theItem;

    InvoiceListViewController *invoiceListViewController=[[InvoiceListViewController alloc] init];
    invoiceListViewController.title=@"Invoice List";
    UIImage *anImage2 = [UIImage imageNamed:@"invoiceNo.png"];
    UITabBarItem *theItem2 = [[UITabBarItem alloc] initWithTitle:@"Invoice List" image:anImage2 tag:2];
    invoiceListViewController.tabBarItem = theItem2;

    NSMutableArray *controllers=[[NSMutableArray alloc] init];
    [controllers addObject:customerListViewController];
    //  [controllers1 addObject:vc1];
    [controllers addObject:selectedCustomerViewController];

    [controllers addObject:invoiceListViewController];
    ///[controllers1 addObject:vc4];
    tabBarController1.viewControllers=controllers;

    [self.navigationController setNavigationBarHidden:YES animated:YES];
    [[self view] addSubview:tabBarController1.view];
    for (int t=0; t<[controllers count]; t++)
    {
        NSLog(@"controller%@",[controllers objectAtIndex:t]);
    }

}

试试这个：

首先在Tabbar controller.m文件上使用以下函数：

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [viewController viewWillAppear:YES];
}

在Tabbar controller.m文件的viewDidLoad函数中，使用localNavigationController.delegate=self；如下例所示

UserListing *nearBy = [[UserListing alloc] init];
nearBy.tabBarItem.image = [UIImage imageNamed:@"icoTabNearby.png"];
nearBy.tabBarItem.title = @"Nearby";
localNavigationController = [[UINavigationController alloc] initWithRootViewController:nearBy];
localNavigationController.delegate = self;

希望它对你有用。

hai，谢谢你的回答。实际上我已经试过了。这仅适用于我的“客户”选项卡，但在这里，我正在“客户”中创建其他3个uiview控制器。t您必须使用localNavigationController.delegate=self；分别适用于所有ViewController
