Question

我有一个基于UITabBarController的应用。它有3个标签。在第一个标签中（默认启动应用时），系统会显示UIImagePickerController以选择相册。但问题是：TabBar将涵盖UIImagePickerController。如何在UIImagePickerController内插入UITabBarController？非常感谢帮助。这是我的代码：

//第一个标签的viewController.m

- (void)loadView 
{

    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    [self presentModalViewController:imagePicker animated:NO];
    [imagePicker release];

}

再次尝试后，我按如下方式修改了一些代码，可以显示标签栏，但无法点击。怎么办？

- (void)loadView 
{

    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:imagePicker animated:NO];
    CGRect rect = CGRectMake(imagePicker.view.frame.origin.x,        
                             imagePicker.view.frame.origin.y, 
                             imagePicker.view.frame.size.width, 
                             imagePicker.view.frame.size.height-self.tabBarController.tabBar.frame.size.height);

    imagePicker.view.frame = rect;
    [imagePicker.view addSubview:self.tabBarController.tabBar];
    [imagePicker release];

}

不要将其显示为模态视图控制器，只需将其视图添加到当前视图控制器：

- (void)loadView {
    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    [self.view addSubview:imagePicker.view];
    [imagePicker release];    
}

如果需要，请不要忘记对框架进行调整。
