ios - 如何在 UITabbarController 中插入 UIImagePickerController

Question

我有一个基于 UITabBarController 的应用程序.它有 3 个选项卡。在第一个选项卡中(启动应用时默认)，UIImagePickerController将显示选择专辑。但问题是:TabBar将被 UIImagePickerController 覆盖.如何插入UIImagePickerController里面UITabBarController ?非常感谢您的帮助。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，我修改了一些代码如下，标签栏可以显示，但无法点击。怎么做？

- (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];

}

与其将其呈现为模态视图 Controller ，不如将其 View 添加到您当前的 View Controller 中:

- (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，不要忘记对框架进行调整。
